Which glutamate receptor(s) are affected negatively by monosodium glutamate: ampa, nmda, and/or kainate?
Could asupplement with aminoacids, vitamins(l-carnitine, l-tartaric acid, potassium chloride, l-leucine, isoleucine, valine, nicotinic)cause damage on brain?
? Migraine: If tyramine problem=migraine, here is a list of foods that are rich in tyramine to avoid triggering headaches: chocolate, yoghurt, all cheese except cottage cheese, smoked/pickled fish/meats (inc herring, caviar, bologna, salami, pepperoni), liver, avocados, bananas, figs, raisins+ red wine. Check out my plate recommendations for food ideas, alternatives. From a fellow migraineur since childhood:). ...Read more
Can autoantibodies against glutamine synthetase and/or glutamate dehydrogenase cause glutamate metabolism disorders?
Still searching: Glutamine synthase is part of the glutamine synthetase family. Ammonia incorporation in animals occurs through the actions of glutamate dehydrogenase and glutamine synthase. Glutamate plays the central role in mammalian nitrogen flow, serving as both a nitrogen donor and nitrogen acceptor. I am unble to find references in my search so far as to autoantibodies to these but see comment. ...Read more
Does exercise increase serotonin by stimulating the uptake of tryptophan by brain synaptosomes(sze py.1976)?

How does dopamine and serotonin (chemically) reduce fear/anxiety in de brain? prefrontal cortex or amygdala? Or which parts of brain is involved?
Neurotransmitters: Medicines like Zoloft/Lexapro are serotonin reuptake inhibitors. Wellbutrin (bupropion) inhibits the uptake of norepinephrine and dopamine. Whether it is anxiety, irritability, anger, short fuse, or depression; these medicines regulate neurotransmitters in the brain to improve symptoms of insomnia, guilty feelings, poor concentration, fatigue, appetite disturbance, and lack of drive/interests. ...Read more
Mitochondrial diseas: A very rare genetic disorder which leads to neurodegeneration. Presenting in infancy or later childhood, the earlier presentation is usually more severe. Those who develop symtpoms later in childhood may survive into adulthood. ...Read more
Since there's deep brain stimulation that stimulate neurons, is there deep brain "inhibition" that inhibits neurons?
Yes: It is interesting that it is called " stimulation", in fact it inhibits the neuron depending upon the degree of stimulation applied. For example the involuntary movement of Parkinson's disease are controlled by "inhibition". Similarly " interstim" is the technique to stimulate to cause inhibition of bladder contractions to cure loss of urinaty control. The entire process is well understood. ...Read more
Pet/ct scan of brain shown bilateral temporal(more severe on left side)parietal, thalami & basal ganglia hypo metabolism.What does it mean, pl advice.
MaybeNothing: Pet/ct can show a region of hypometabolism, yes. But you describe many areas, including bilateral areas. That is much harder to accurately define on these kinds of tests, and results should be viewed with caution. Also, remember that the metabolism images should fit with what is wrong with the patient. ...Read moreSee 1 more doctor answer
GABA receptor: Like many ligands, gaba binds to its specific receptor, the gaba receptor (with several subtypes). Depending on the location of the gaba receptor, binding of gaba modulates various signaling pathways in the body. Note that gaba receptors are also found in organs outside of the brain. ...Read more
Does alcohol consumption aggravate tinitis and/or sensorineural hearing loss? Iv heard that alcohol kills brain cells (so that means neural cells) ..
What is a nonspecific heterogeneous calciric density along tje right paramedian posterior cingulate gyrus versus splenium of the corpus callosum?
Chronic: The report describes a prior area of pathology which has become calcified over a period of years. This represents an archaic process, and has been uncovered coincidently. Unlikely to correlate with current issues. However, discuss with your physician to be complete. ...Read moreSee 1 more doctor answer
A 14x6x6mm non-enhancing signal abnormality inferior to the basal ganglia, no high rcbv, te 135ms cho/naa ratio - 1.3: heterotopia? Low grade?
Serial Imaging : Your MRI could be consistent with low grade neoplasm or a benign finding. The best option in these cases where it is unclear is to follow the area closely with repeat MRI at say 3 month intervals. If this is benign it will stay the same. If it grows it is likely a neoplasm. ...Read more
Atomoxetine inhibits serotonin transporter, dopamine transporter and naroephinephrine. What does inhibit mean?
Strattera (atomoxetine): Inhibition is the opposite of stimulation, so the effectiveness is reduced. ...Read more
