    Blood Sugar Is Controlled Mostly By The Brain, Not Pancreas

    Ray wrote in one of his articles that pancreatic insulin is responsible for no more than 20% of glycemic control. While he mentioned potassium as the major factor, he also said that it is the brain that ultimately controls the levels of sugar in the blood. This study from Yale seems to confirm...

    Why glucose oxidation is preferable to fatty acid oxidation

    I have seen this question come up many times on the forum. This study offers a potential answer and even though it focuses only on brain metabolism the given reasons are applicable for most other tissues as well. http://www.ncbi.nlm.nih.gov/pubmed/23921897 "...It is puzzling that hydrogen-rich...

    Brain Levels Of Gaba Predict Tactile Learning Ability

    This study is perhaps counter-intuitive to some given that GABA is the major inhibitory neurotransmitter in the CNS. However, GABA has repeatedly been shown to be crucial for the ability of the brain to learn and cholinergic drugs that were tried for Alzheimers failed spectacularly. For those...

    Running Marathons Shrinks The Brain

    Not that this is any surprise to the forum readers, but I found it quite alarming that the brain shrinks in a such a short amount of time even though the study claims that the brain recovers within 6 months after the event. What I found also interesting is the explanation for the shrinkage - the...

    Role Of Low-Level Laser Therapy In Neurorehabilitation

    www.ncbi.nlm.nih.gov/pmc/articles/PMC3065857/ Abstract This year marks the 50th anniversary of the discovery of the laser. The development of lasers for medical use, which became known as low-level laser therapy (LLLT) or photobiomodulation, followed in 1967. In recent years, LLLT has become...

    Glucocorticoids Cause Brain Damage

    For the last few years, studies on the use of glucocorticoids ( prednisone, dexamethasone,ect) resulted in a smaller hippocampus and prefrontal cortex. Causing memory loss, attention loss and lower concentration. This study shows that Prednisone can actually reduce brain weight and decrease...

    The Effect Of Magnesium Sulfate On Cerebral Blood Flow Velocity, Cardiovascular Variables, And Arter

    http://www.ncbi.nlm.nih.gov/pubmed/10213436 Abstract Although there are data demonstrating reversal of cerebral vasospasm with magnesium sulfate, there is little information on the effects of magnesium on the normal intact cerebral vasculature. This study investigated the actions of magnesium...

    Blocking Inflammation From PUFA Reverses Brain Aging

    This study is important on several levels. First, it shows that it is possible to fully reverse brain aging. Second, it suggests that one of the main mechanisms for brain aging is inflammation induced by the primary metabolites of PUFA - the leukotrienes. I talked about them in my first show...

    Cyproheptadine Prevents Brain Damage From Stroke

    The effect was dose dependent and higher doses of cyproheptadine completely prevented the nervous system damage caused by stroke. Bufotenin, a type of serotonin, prevented the protective effects of cyproheptadine indicating that damage in stroke conditions is at least partially mediated by...

    Glucose has the same effect on the brain as glycine

    Related to the other study on glucose I posted minutes ago. This study shows that just like glycine, taurine, and beta alanine glucose is a glycine "receptor" agonist. As such, it has an inhibitory effect on the brain and spinal cord and likely has similar effects to glycine on variety of...

    Melatonin Elevates Brain Serotonin

    Carbs (not Meat) Were Crucial Factor For Developing Big Brains
