His work bridged the gap between psychology and neurobiology.

Our perception of quantity, separate from counting or estimation of magnitude more generally, is foundational to human cognition, according to some neuroscientists.

Research in recent decades has explored how animals other than humans perceive different numbers of objects

Some nerve cells in the brains of macaques respond selectively to particular numbers, hinting at a specialized pathway for extracting information about numerical quantity.

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.

Since Darwin published his landmark work on natural selection, we’ve understood that we’re animals. But that doesn’t mean we really believe it.

The cephalopods resisted temptation for up to 130 seconds to earn their favorite food, hinting at sophisticated cognitive abilities such as planning for the future.

Check out the optical illusion that researchers put before canines, finding that fido and master have opposite reactions.

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.

A population of North Island robins in a New Zealand sanctuary provides a unique system for investigating the memory skills of birds in the wild.
