“This was a surprise, because the effect on intelligence (IQ) was irrespective of age. Another study was able to experimentally demonstrate these enhancements of learning and memory in mice as well using a mouse version of this particular polymorphism.”

“Another study found that seniors who had the worst test scores on a smell test were 2.2 times more likely to show signs of mild cognitive decline. Olfactory cells in the nose that are responsible for a sense of smell require a constant supply of new stem cells from the olfactory bulb, a region in the forebrain.”

“Women with a higher concentration of Bacteroides in their guts had a larger volume of the hippocampus, a region involved in learning and memory, and more gray matter in the frontal cortex and insula, brain regions involved with complex processing of information.”

“Repetitive transcranial magnetic stimulation uses a magnetic field to stimulate a brain region (dorsolateral prefrontal cortex) that plays an important role in mood regulation, decision making, and memory.”

“Living in places with exposure to very fine air pollutant particles doubled dementia risk in older women, poor performance on memory tests was found in 19,000 retired nurses for every additional 10μg/m3 of polluted air they breathed, MRI scans reveal more brain atrophy in people that live close to the highway in a dose-dependent manner in more than one study.”

“A kind of Miracle-Gro for the brain, BDNF stimulates the hippocampus -- the brain's center of learning and long-term memory -- to sprout new neurons, and it increases connections between neurons. [...]”

“> The analysis revealed that for both the aerobic and stretching groups, brain volume increased in most gray matter regions, including the temporal lobe, which supports short-term memory.”

“A review of randomized controlled trials found that people generally had enhancements in working memory performance and improved visual information processing after eating cocoa flavanols.Eating cocoa after a night of total sleep deprivation actually counteracted the cognitive impairment that lack of sleep can cause.”

“Impaired brain glucose uptake also plays a causal role in tau tangle formation, another hallmark of Alzheimer's disease. Executive function involves higher-level cognitive skills that include working memory, flexible thinking, and self-control.”

“[...] "I was fascinated to see similarities between the pattern of brain activity in a psychedelic state and the pattern of brain activity during dream sleep, especially as both involve the primitive areas of the brain linked to emotions and memory.”
