“The reduction in brain activity in regions of the brain required for attention and rapid decision-making but they correlated with improvements on the cognitive tests. The less someone’s brain had to work to maintain attention and make quick decisions, the better that person typically performed on the tests of general thinking ability.”

“Two key cleanup routes in brain cells depend on GTP: Endocytosis brings materials into the cell for sorting or breakdown. Autophagy dismantles worn or damaged components and delivers them to the lysosome, a small acidic compartment that digests waste.”

“Findings from a recent study suggest that brain-derived oleic acid activates neural stem cells in the hippocampus, promoting neurogenesis – the generation of new neurons. The hippocampus is a small organ located within the brain's medial temporal lobe.”

“They found that norepinephrine fluctuations triggered by the brain's locus coeruleus drove rhythmic changes in blood vessel size. This facilitated the movement of cerebrospinal fluid into the brain and the removal of waste products.”

“A common type of fungus, Candida albicans, was shown to cross the blood-brain barrier and trigger an inflammatory response in the brain that results in memory impairment (mouse study).”

“Several studies have identified the gut-brain relationship is bidirectional such that changes in the gut microbiome can affect behavior, and behavioral changes (ie. psychological stress) can affect the gut flora.”

“People often describe taking psilocybin as producing a dreamlike state and our findings have, for the first time, provided a physical representation for the experience in the brain." > [...] The mind tips into a more chaotic regime where there are more networks available than normal.”

“Extra-virgin olive oil protects nerve cell structure and function, improves learning and memory, and reduces the amyloid-beta plaques and neurofibrillary tangles in the brain in mice genetically engineered to get Alzheimer's disease.”

“As many as 10 million people living in the United States have low iron levels. Findings from a new study suggest that iron levels in the basal ganglia region of the brain during youth influence cognitive ability.”

“A new study demonstrates that consuming low-calorie sweeteners in tandem with carbohydrate-rich foods alters brain function and impairs metabolism. The health effects of consuming low-calorie sweeteners are not well understood.”
