Even in the nervous system of a single species such as humans, hundreds of different types of neurons exist, with a wide variety of morphologies and functions. These include sensory neurons that transmute physical stimuli such as light and sound into neural signals, and motor neurons that transmute neural signals into activation of mucles or glands; however in many species the great majority of neurons receive all of their input from other neurons and send their output to other neurons.

Some research suggests that restless legs syndrome may be due to nerve impairment in the spinal cord. It had been thought that such abnormalities were likely to originate from nerve pathways in the lower spine. However, some patients with RLS commonly have symptoms in the arms suggesting that the upper spine may be involved as well. One 2001 study suggested that in patients with RLS and PLMD there is an abnormal over-excitable response along the entire spinal cord, which is triggered by sleep-related factors.
Other research suggests that neurologic abnormalities involved with RLS and PLMD originate in the brain. A variety of studies support the hypothesis that an imbalance in neurotransmitters (chemical messengers in the brain), notably dopamine and serotonin, may play a part in RLS. Dopamine and serotonin unleash an array of nerve impulses that affect muscle movement.
Some experts suggest that RLS, particularly if it occurs in older adults, may be a form of neuropathy, which is an abnormality in the nervous system outside the spine and brain. Nevertheless, there is no evidence of a causal relationship.
Electromyography and nerve conduction studies may be recommended to measure electrical activity in muscles and nerves, and Doppler sonography may be used to evaluate muscle activity in the legs. Such tests can document any accompanying damage or disease in nerves and nerve roots (such as peripheral neuropathy and radiculopathy) or other leg-related movement disorders.

VITAMINS AND SUPPLEMENTS
"Lecithin acts like motor oil for your nervous system, keeping everything firing away smoothly and efficiently. It contains phosphatidylcholine (PC), which is broken down into choline and then acetylcholine, a nerve chemical which is key for brain function. Lecithin is also uniquely suited for supporting the nervous system. In fact, after strenuous exercise, choline levels drop in the body, and this drop is linked to fatigue. The lower choline levels result in lower acetylcholine, which means nerve impulses (the messengers that tell your muscles when to work) travel slower, leading to slower reaction times and even more fatigue."

"Lecithin helps the body digest and utilize the fats and oils that are critical in maintaining efficient brain and nerve function. Perhaps the greatest recent discovery is the use of lecithin to activate a sluggish mind and improve memory by providing the body with the ingredients necessary to produce the vital neurotransmitter acetylcholine. This is the neurotransmitter that is responsible for memory storage and retrieval and the effectiveness of nerve signals in many areas of the brain. Your brain, if dried and analyzed, would show a composition of about 30% of lecithin."

vitamin b6 (pyridoxine hydrochloride)
"The role of vitamin B6 in our nervous system is very broad, and involves many aspects of neurological activity. One aspect focuses on the creation of an important group of messaging molecules called amines. The nervous system relies on formation of these molecules for transmission of messages from one nerve to the next. (The molecules can be classified as "neurotransmitters" for this reason.) Amines are one type of neurotransmitter in the nervous system. They are often made from parts of protein called amino acids, and the key nutrient for making this process happen is vitamin B6. Some of the amine-derived neurotransmitters that require vitamin B6 for their production include serotonin, melatonin, epinephrine, norepinephrine, and GABA. The key role of vitamin B6 in the nervous system also results in many nerve-related symptoms when B6 is deficient. These symptoms can include convulsions and seizures in the case of severe deficiency. The critical role of vitamin B6 in the formation of red blood cells means that B6 deficiency can also result in symptoms of anemia, malaise, and fatigue. When anemia is exclusively related to B6 deficiency, it is usually classified as hypochromic, microcytic (pernicious) anemia."

"Taking advantage of new advances in electronic measuring techniques, the scientists studied the electrical conduction of currents by the nerves. Their most important finding was that while calcium is the prime conductor of these minute electrical currents, it is magnesium that maintains normal levels of calcium in the system. How does magnesium regulate calcium levels? Inside the body, these two minerals are positively charged. When they come into contact with negatively charged particles, an electrical current is formed. It is believed that fatty acids comprising the major portion of nerve tissue are negatively charged. It is for this reason, then, that calcium and magnesium supplies must be constantly renewed; without them, the flow of current by the nerves cannot be maintained. Magnesium works in other ways to preserve the health of the nervous system. By the twentieth century, doctors had learned that magnesium injections exert a depressant effect upon the nerves. In fact, one of the early uses of the mineral was to induce sleep. It is significant that hibernating animals have very high magnesium levels. Magnesium has also been shown effective in controlling convulsions, in pregnant women, epileptic seizures, and "the shakes" in alcoholics."

"Neurons communicate or send impulses through an action potential., This takes place from the dendrite and all the way to the axon ends. An action potential is a change of voltage within the axon. In other words, the negative state off the inner axon turns positive when the impulses comes by. This happens by the use of a sodium and potassium pump. Sodium [Na] surrounds the axon with a positive charge, while the potassium [K] is within the axon. As an impulse enters at the axon hillock, the sodium, potassium pump puts positive sodium into the axon while it puts negative potassium out of the axon. As more sodium enters the potential of the impulse changes from -70 mV to +30 mV, (a difference of 100 mV) This change is called an action potential. The sodium, potassium pump works furiously to pass the impulse through the axon. As the impulse leaves the axon, it is reverted to a normal state which is called the resting potential. At the end of the axon, the impulse or stimulus enters the synapses and is called a post synaptic potential. From here, the impulse is transferred into neurotransmitters, some of which are chemicals called epinephrine and dopamine. These neurotransmitters flow into the fluid filled gap called the synaptic cleft and enter the dendrites. And, again, the process is repeated."

Scientists think this pain-relief activity is linked to the stimulation of nerves that further stimulate the body's own natural pain relief mechanisms."

"In the central nervous system of rats, curcumin exerts a protective effect against neurodegeneration. Possible mechanisms of neuroprotection exerted by curcumin include inhibition of glutamate-mediated excytotoxicity, antioxidant activity, and induction of chaperone proteins. Indeed, in cultured neurons, treatment with curcumin reduced cell demise mediated by glutamate-induced Ca(2+) influx and caspase-3 activation. The possible use of curcumin as a neuroprotective drug is of potentially enormous importance; indeed neurodegenerative diseases such as AD affect millions of people world-wide and are becoming a dramatic health emergency in developed countries."

Despite current rigorous treatment protocols, effect of chemotherapy has failed to improve patient outcome significantly. The results demonstrate that curcumin exerts inhibitory action on glioma cell growth and proliferation via induction of cell cycle arrest instead of induction of apoptosis in a p53-dependent manner, and ING4 possibly is in part involved in the signal pathways."

"A prayer was answered the day I emailed Dr. Cole. His team at UCLA has developed a formulation of "Optimized Curcumin" that works more like a drug with "super bio-availability." UCLA's Curcumin was not only crossing into the blood stream it was crossing through the blood brain barrier (BBB). The BBB is a membranic structure in the central nervous system (CNS) that restricts the passage of various chemical substances and things like bacteria between the bloodstream and the neural tissue itself, while still allowing the passage of substances like oxygen that is essential to metabolic function."

"It would appear that H. procumbens secondary root aqueous extract (HPE) produces its anticonvulsant activity by enhancing GABAergic neurotransmission and/or facilitating GABAergic action in the brain. In general, the average onset of convulsion was delayed, while the average duration of convulsion was markedly reduced. The plant's extract also depressed the central nervous system (CNS). It is, therefore, thought that the anticonvulsant property of the herb may be linked, at least in part, to its ability to depress the central nervous system."

"Ginkgo is one of the herbs with documented antioxidant properties. Studies in France have shown ginkgo to be very effective in protecting the lipid (fat) portion of cellular membranes from free radical damage. If one considers that the brain cells contain the highest content of unsaturated fats (lipids) of any cells in the body, this protective action further supports ginkgo's benefits for the central nervous system. Free radical damage in the rain and nervous system is widely postulated to be a major cause of accelerated aging."

The mechanism of action is not yet well understood. Three of the ingredients of the extract have been isolated and found to be pharmacologically active, but which one alone or in combination is responsible for clinical effects is unknown. it was established that the electrophysiological effects of EGb in CNS are similar to those of well-known cognitive activators such as "nootropics" as well as tacrine, the only marketed "antidementia" drug currently available in the United States."

skullcap (scutellaria lateriflora)
"The phytochemistry and biological activity of Scutellaria lateriflora L. (American skullcap) which has been traditionally used as a sedative and to treat various nervous disorders such as anxiety was studied. In vivo animal behaviour trials were performed to test anxiolytic effects in rats orally administered S. laterifolia extracts. Significant increases in the number of entries into the center of an "open-field arena"; number of unprotected head dips, number of entries and the length of time spent on the open arms of the Elevated Plus-Maze were found. The identification and quantification of the flavonoid, baicalin in a 50% EtOH extract (40 mg/g) and its aglycone baicalein in a 95% EtOH extract (33 mg/g), as well as the amino acids GABA in H2O and EtOH extracts (-1.6 mg/g) and glutamine in a H2O extract (31 mg/g), was performed using HPLC. These compounds may play a role in anxiolytic activity since baicalin and baicalein are known to bind to the benzodiazepine site of the GABAA receptor and since GABA is the main inhibitory neurotransmitter."

"Traditionally, skullcap is known to be an effective stimulant for the nervous organization, as the herb contains high value ingredients for a sound nervous system. The herb is particularly effective in helping as well as escalating the nervous system when a person undergoes mental and physical stress and strain. In fact, skullcap is a time tested medicine for all kinds of disturbed mental state, be it tension, anxiety, insomnia, neurasthenia, panic, headaches, fatigue, depression as well as melancholy."

"Rats that received a weak solution of the three herbal fluid extracts of Scutellaria lateriflora (Skullcap), Gelsemium sempervirens (Gelsemium) and Datura stramonium (Jimson Weed) displayed no seizures during treatment while all the other groups were not seizure-free. However, when this treatment was removed, the rats in this group displayed numbers of spontaneous seizures comparable to the controls. Although there is no proof that herbal remedies can control limbic or temporal lobe epilepsy, the results of this experiment strongly suggest that the appropriate combination of herbal compounds may be helpful as adjunctive interventions."

"A meta-analysis assessing 23 of the double-blind trials was published recently,5 and will not be replicated in this article. In summary, most patients in the reports had mild to moderately severe depression. (In mild depression the patient is distressed by depressive symptoms but will probably be able to perform most activities; symptoms are more numerous and intense when depression is of moderate severity, and the patient is likely to have significant difficulty in continuing with ordinary activities.) Three trials included patients with severe depression. Most trials lasted four to eight weeks. Across all reports, 50%-80% of patients improved with SJW, a rate similar to that achieved with conventional antidepressants."

A possible mechanism by which a valerian extract may cause sedation is by increasing the amount of gamma aminobutyric acid (GABA, an inhibitory neurotransmitter) available in the synaptic cleft. Results from an in vitro study using synaptosomes suggest that a valerian extract may cause GABA to be released from brain nerve endings and then block GABA from being taken back into nerve cells

Because of the more favourable adverse effect profile of valerian compared to oxazepam, this hypothesis should be analysed confirmatorily in an equivalence study."

"Over the past several decades, valerian has undergone rather extensive chemical, pharmacological, and clinical studies. Its aqueous extract has been found to be mostly responsible for its sleep-inducing effect, while the volatile oil (mainly valerenic acid) and the valepotriates (through their degradation products) are major contributors to its sedative effects. Current data also indicate the valepotriates to be responsible for the antianxiety or tranquilizing effect of valerian. No serious toxic side effects associated with the clinical use of valerian have been reported."

"One mapped brain activity with functional MRI and found that stimulating an acupuncture point on the little toe, used for eye disorders, triggers activity in the brain's visual cortex. "There is no question it is working through the nervous system," says Zang- Hee Cho, the study author and a radiologist at the University of California- Irvine. Other research suggests that acupuncture may trigger the release of endorphins, the body's natural painkillers, and other brain chemicals. That effect might explain how acupuncture fights nausea, say researchers in the JAMA chemotherapy trial. And Arthur Margolin of Yale University School of Medicine, an author of the August addiction study, says acupuncture activates the "parasympathetic" part of the nervous system, which has a calming effect that reduces cravings."

"When people drink alcohol, it's absorbed into their bloodstream. From there, it affects the central nervous system (the brain and spinal cord), which controls virtually all body functions. Because experts now know that the human brain is still developing during our teens, scientists are researching the effects drinking alcohol can have on the teen brain."
"Alcohol." TeensHealth kidshealth.org/teen/drug_alcohol/alcohol/alcohol.html
"Because alcohol is highly neurotoxic, as we've said before, it leads to damage of the brain and nervous system. Over time it can cause cognitive deficits, or loss of mental abilities in areas such as memory, concentration, motor control and ability to learn. However, there is some hope now that those precious brain-cells are not lost for ever. Researchers at Stanford University have found that after at least six months of sobriety, the brain damage caused by alcohol's toxicity does in fact repair itself. They concluded that the mental abilities of their study group of long-term alcoholics, who had all been sober for between six months and thirteen years, were now the same as their control group who had not been alcoholics. The only capability that had not been recovered was spatial awareness."

"It is suggested that its use as an artificial sweetener for soft drinks may cause human neurochemical changes that could have functional or behavioral consequences.

"Compared to other environmental factors putatively linked to brain tumors, the artificial sweetener aspartame is a promising candidate to explain the recent increase in incidence and degree of malignancy of brain tumors. Evidence potentially implicating aspartame includes an early animal study revealing an exceedingly high incidence of brain tumors in aspartame-fed rats compared to no brain tumors in concurrent controls, the recent finding that the aspartame molecule has mutagenic potential, and the close temporal association."

"Caffeine belongs to the xanthine chemical group. Adenosine is a naturally occurring xanthine in the brain that is used as a neurotransmitter at some synapses. One effect of caffeine is to interfere with adenosine at multiple sites in the brain including the reticular formation."
Eric H. Chudler, Ph.D. "Effects of Caffeine on the Nervous System." Neuroscience For Kids faculty.washington.edu/chudler/caff.html
"Three main mechanisms of action of caffeine on the central nervous system have been described. Mobilization of intracellular calcium and inhibition of specific phosphodiesterases only occur at high non-physiological concentrations of caffeine. The only likely mechanism of action of the methylxanthine is the antagonism at the level of adenosine receptors. Caffeine increases energy metabolism throughout the brain but decreases at the same time cerebral blood flow, inducing a relative brain hypoperfusion. Caffeine activates noradrenaline neurons and seems to affect the local release of dopamine. Many of the alerting effects of caffeine may be related to the action of the methylxanthine on serotonin neurons. The methylxanthine induces dose-response increases in locomotor activity in animals. Its psychostimulant action on man is, however, often subtle and not very easy to detect. The effects of caffeine on learning, memory, performance and coordination are rather related to the methylxanthine action on arousal, vigilance and fatigue. Caffeine exerts obvious effects on anxiety and sleep which vary according to individual sensitivity to the methylxanthine. However, children in general do not appear more sensitive to methylxanthine effects than adults."

"Because caffeine is primarily an antagonist of the central nervous system's receptors for the neurotransmitter adenosine, the bodies of individuals that regularly consume caffeine adapt to the continuous presence of the drug by substantially increasing the number of adenosine receptors in the central nervous system. First, the stimulatory effects of caffeine are substantially reduced, a phenomenon known as a tolerance adaptation. Second, because these adaptive responses to caffeine make individuals much more sensitive to adenosine, a reduction in caffeine intake will effectively increase the normal physiological effects of adenosine, resulting in unwelcome withdrawal symptoms in tolerant users."

"Some examiners claim that ataxia is one of the most common disorders produced by gluten in relationship to our nervous system. Poor coordination and clumsiness does occur with gluten intolerance and affects children as well as adults. But how does gluten cause our brains to function improperly and cause this imbalance? Evidence suggests that it is all due to the immune system's reaction to gluten itself. In your cerebellum (a part of the brain that plays an important role in the integration of sensation and control of movement), there are special cells called Purkinje cells. These cells are found in your cerebellum and are the main components of the "balancing center." In patients with gluten sensitivity, it has been shown that these individuals have antibodies against these Purkinje cells. The antibodies made against gluten (anti-gliadin antibodies) cross-react against these Purkinje cells. What this means is that in a person who is genetically at-risk for gluten sensitivity, gluten induces an immune attack against the protein gliadin, and this antibody not only attacks gliadin, but also attacks tissues far away from the intestines. In this case, through the bloodstream, these antibodies travel to the cerebellum and attack the Purkinje cells. As these cells become inflamed from the immune attack, the ability to coordinate all the "balance information" is impaired. Symptoms of poor balance and coordination then result."
"How Gluten Creates Problems in the Nervous System." The Gluten Doctors (Aug 21, 2011). glutendoctors.blogspot.com/2011/08/how-gluten-creates-problems-in-nervous.html
"One idea is that antibodies generated by food proteins or peptides can attack the brain. This immune mistake is generally known as molecular mimicry. A second idea is that gluten proteins or peptides generated from them during digestion can act directly on the brain. A third idea is that your brain is affected by immune responses in other parts of your body. All immune activity sends signals to the brain to change behavior and to recruit a range of defensive responses. Disturbances to brain function vary from routine effects such as sleepiness, fogginess, and brief episodes of confusion to symptoms of major mental or neurological illness. For example, people with celiac disease suffer for many years before the diagnosis is made. They often state that they never feel well. Most of these patients will report episodes of fatigue with cognitive dysfunction; difficulty concentrating, mental "fogginess", recent memory dropouts. They complain of mood liability and are often tearful and irritable. They return to normal when they no longer eat problem foods."
Stephen Gislason MD, "Gluten Problems and Solutions." Alpha Education Books Rev. 2011
"Celiac disease is a digestive condition triggered by consumption of the protein gluten, which is found in bread, pasta, cookies, pizza crust and many other foods containing wheat, barley or rye. If you have celiac disease and eat foods containing gluten, an immune reaction occurs in your small intestine, causing damage to the surface of your small intestine and an inability to absorb certain nutrients. Eventually, the decreased absorption of nutrients (malabsorption) that occurs with celiac disease can cause vitamin deficiencies that deprive your brain, peripheral nervous system, bones, liver and other organs of vital nourishment. This can lead to other illnesses and stunted growth in children."

monosodium glutamate (msg)
"Early on (in the 50s) studies reported significant issues relating to the exposure of mammals to MSG. If neonatal rats were given a single exposure to MSG, the neurons in the inner layer of their retina were killed. It was also reported that certain parts of their brains were injured as well (the hypothalamus). When considering various findings of MSG exposure in the rat, remember that humans are some 5-6 times more sensitive to MSG than rats."

Plasma norepinephrine (NE) levels were not significantly different between normal subjects or hypertensive patients while on low sodium intake. But during high sodium intake, they decreased significantly (P less than 0.05) in normal subjects (from 22 +/- 3.4 to 12 +/- 2.3 ng/dl) and in salt-resistant patients (from 17 +/- 4.5 to 13 +/- 2.4 ng/dl) but not in salt-sensitive patients (from 20 +/- 1.9 to 22 +/- 3.2 ng/dl). Furthermore, the majority of salt-sensitive patients displayed inappropriately high plasma NE in relation to their urine excretion of sodium during high sodium intake. Finally, the increments in plasma NE after 5 min of standing were significantly greater in salt-sensitive patients than they were in salt-resistant patients and normal subjects during both low or high sodium intake. These data indicate that a subset of patients with essential hypertension may have impaired suppressibility of plasma NE during high sodium intake, which suggests hyperactivity of the sympathetic nervous system in these patients. These aberrations may be responsible for the increase in MBP in the salt-sensitive patients during high sodium intake."

"Americans eat about 1 1/2 teaspoons of salt daily, more than double what they need for good health and enough to increase the risk of high blood pressure, strokes and other problems. Most of that sodium doesn't come from the table salt shaker; it's hidden inside common processed foods and restaurant meals. The American Medical Association has said 150,000 lives a year could be saved by cutting in half sodium levels in processed and restaurant food."

"Dr. Martin classified refined sugar as a poison because it has been depleted of its life forces, vitamins and minerals. "What is left consists of pure, refined carbohydrates. The body cannot utilize this refined starch and carbohydrate unless the depleted proteins, vitamins and minerals are present. Nature supplies these elements in each plant in quantities sufficient to metabolize the carbohydrate in that particular plant. There is no excess for other added carbohydrates. Incomplete carbohydrate metabolism results in the formation of 'toxic metabolite' such as pyruvic acid and abnormal sugars containing five carbon atoms. Pyruvic acid accumulates in the brain and nervous system and the abnormal sugars in the red blood cells."

"Processed sugar has many harmful effects throughout the body and can cause major imbalances in the organ systems. You could say that sugar tends to throw off the homeostatic balance of the whole body by increasing the production of adrenaline by many times. In essence, sugar stimulates the nervous system by inducing a flight or fight response."

"It is well known that too much sugar causes tooth decay, but might it also cause "brain decay?" Recent research suggests that it just might. With the growing epidemic of obesity in the US, the number of people with diabetes is also increasing. Diabetes is due to the body's inability to maintain a constant level of sugar in the blood, as it should. Over time, this results in problems in many parts of the body, including the kidneys, heart, muscles, nerves and brain."
