Researchers are using visual tricks to try to better understand canine perception.

Researchers use optical illusions to investigate canine perception.

Conversations between the immune and central nervous systems are proving to be essential for the healthy social behavior, learning, and memory.

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.

Rats and equations help researchers develop a theory of how our brains keep track of when events took place.

Signals from the lateral entorhinal cortex help create “time cells” in the hippocampus, according to some researchers.

Researchers discover a fragment of cord between 41,000 and 52,000 years old that points to Neanderthals’ complex cognitive abilities.
