Dietary Spermidine Boosts Cognition in Insects and Rodents
Mice and flies given the polyamine in their diet have increased brain cell metabolism and cognitive function, and epidemiological data hints at a similar benefit in humans.

Dreamers answered experimenters’ questions or solved simple math problems, showing that complex two-way communication between the dreaming and waking world is possible.
Technologies such as noninvasive brain stimulation and virtual reality gaming offer insights into how dreams arise and what functions they might serve.
Several routes exist for immune cells to communicate with neurons in the central nervous system, though T cells rarely come in direct contact with neural tissue.
People who show low social engagement over long periods of time often show reductions in cognitive function. Studies of the brain may provide clues about this correlation.
Absence of human contact is associated with declines in cognitive function. But as the COVID-19 pandemic brings concerns about the potential harms of isolation to the fore, researchers are still hunting for concrete evidence of a causal role as well as possible mechanisms.
