cognition

Scientists find that two species can be trained to distinguish quantities that vary by one.

A research group argues that a species’ number of neurons, rather than brain volume, should serve as indicator of cognitive capacity when studying brain evolution, but some experts voice doubts.

A study that transfused plasma from active to inactive mice suggests the protein clusterin enhances cognition.

In Chapter 1, “On Being,” author Antonio Damasio outlines the dawn of consciousness.

Kyoto University is shuttering its Primate Research Institute after its director was dismissed for misuse of funding.

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.
