“To their surprise, they found cells producing BDNF in a part of the brain's hypothalamus called the paraventricular nucleus. > "We knew that in embryonic development, some blood cells do go to the brain and become microglial cells," said Chan.”

“The process of growing new neurons is called neurogenesis and it is highly active during brain development but whether it occurs in adults has been unclear. An animal study published last year had shed some doubt on adult neurogenesis claiming it does not occur.”

“This paper supports the premise of my recent publication on how on omega-3 regulates serotonin production and function in the brain.”

“Omega-3 fatty acids play critical roles in maintaining brain health and function, potentially reducing the risk of developing Alzheimer's disease. People who carry the APOE4 gene variant and those with obesity have a higher risk of developing the disease, suggesting that differences in metabolism could be a factor.”

“They also noted that the improvements in cognitive function were not correlated to improvements in mental health. These findings suggest that the variable effects of exercise on brain function are related to a genetic variant that influences the production of BDNF.”

“Studies on human cells are next. The significance of being able to turn a skin cell into a neuron is the potential replacement of damaged or dead neurons found in neurodegenerative disorders and other brain injuries.”

“Following alcohol consumption, the brain uses acetate, a metabolic byproduct of alcohol, for energy instead of glucose. As a result, glucose levels in the brain drop, and acetate levels increase – even after the effects of alcohol wear off.”

“FTA: > Scientists have discovered a mechanism in the brain that may drive our appetite for foods rich in glucose and could lead to improved treatments for obesity.”

“Some brain tumors remain incurable even after surgery, radiation, and chemotherapy and are often linked to a short life expectancy. To explore a potential new therapy, researchers analyzed long-term data from an earlier brain tumor vaccine trial to determine whether the treatment was associated with longer survival and improved tumor control.”

“In the short term, smoking thickens blood and drives up blood pressure, both of which can increase the risk of a brain bleed. These effects can be reversed by stopping smoking. But smoking also induces permanent changes in the structure of artery walls, say the authors.”
