Vision cells can pull double duty in the brain, detecting both color and shape
Neurons in a brain area that handles vision fire in response to more than one aspect of an object, countering earlier ideas, a study in monkeys finds.

In mice, a high-fat diet cuts a ‘brake’ used to control appetite
A fatty diet changes the behavior of key appetite-regulating cells in a mouse brain.

Mice and bats’ brains sync up as they interact with their own kind
The brain activity of mice and bats aligns in social settings, a coordination that may hold clues about how social context influences behavior.

Female rats face sex bias too
In neurobiological studies, male lab animals tend to outnumber females, which are considered too hormonal. Scientists say it’s time for that myth to go.

Extra fingers, often seen as useless, can offer major dexterity advantages
Two people born with six fingers on each hand can control the extra digit, using it to do tasks better than five-fingered hands, a study finds.

A new experiment didn’t find signs of dreaming in brain waves
Brain activity that powers dreams may reveal crucial insight into consciousness, but a new study failed to spot evidence of the neural flickers.

A cognitive neuroscientist warns that the U.S. justice system harms teen brains
The U.S. justice system holds adolescents to adult standards, and puts young people in situations that harm their development, a researcher argues.
