Cognition

Crows recently demonstrated an understanding of the concept of zero. It’s only the latest evidence of animals’ talents for numerical abstraction — which may still differ from our own grasp of numbers.

Some populations of neurons simultaneously process sensations and memories. New work shows how the brain rotates those representations to prevent interference.

The learning algorithm that enables the runaway success of deep neural networks doesn’t work in biological brains, but researchers are finding alternatives that could.

New research finds that the subjective experience of time is linked to learning, thwarted expectations and neural fatigue.

The heartbeat and other bodily processes play a surprising role in shaping perception and cognition.

As Scarlett Howard taught honeybees to do arithmetic, they showed her how fundamental numbers might be to all brains.

Beneath our awareness, the brain lets certain kinds of stimuli automatically capture our attention by lowering the priority of the rest.

A brain circuit that suppresses distracting sensory information holds important clues about attention and other cognitive processes.

A report that a fish can pass the “mirror test” for self-awareness reignites debates about how to define and measure that elusive quality.
