Cognitive strategies for augmenting the body with a wearable, robotic arm

Scientists show that breathing may be used to control a wearable extra robotic arm in healthy individuals, without hindering control of other parts of the body.

Deep neural networks show promise as models of human hearing

In the largest study yet of deep neural networks trained to perform auditory tasks, researchers found most of these models generate internal representations that share properties of representations seen in the human brain when people are listening to t…

Scientists unveil complete cell map of a whole mammalian brain

Researchers have created a complete cell atlas of a whole mammalian brain. This atlas serves as a map for the mouse brain, describing the type, location, and molecular information of more than 32 million cells and providing information on connectivity …

Traces of trauma in the young brain — and how to erase them

In research conducted on mice a team discovered brain mechanisms that go awry as a result of exposure to trauma in infancy and showed that these changes may be reversible if treated early.   

What happens in the brain while daydreaming?

During quiet waking, brain activity in mice suggests the animals are daydreaming about a recent image. Having daydreams about a recently viewed image predicted how the brain would respond to the image in the future. The findings provide a clue that day…

How stress activates neurons that disrupt sleep

New research reveals that neurons in the preoptic hypothalamus — the region of the brain that regulates sleep and body temperature — are rhythmically activated during non-rapid eye movement sleep (NREM). Stress activates these brain cells out of turn…

Smoking causes brain shrinkage, study finds

Smoking shrinks the brain and effectively causes premature brain aging, according to a new study. Quitting smoking prevents further loss of brain tissue but doesn’t restore the brain to its original size.

Genetic ‘protection’ against depression was no match for pandemic stress

Living through a historic pandemic while handling the stress of the first year of college sent one-third of students in a new study into clinical depression. That’s double the percentage seen in previous years of the same study. And while certain gene…

Advanced MRI technology detects changes in the brain after COVID-19

Researchers have examined the brains of 16 patients previously hospitalized for COVID-19 with persisting symptoms. They have found differences in brain tissue structure between patients with persisting symptoms after COVID-19 and healthy people. Their …

Study reveals a protein called snail may play a role in healing brain injury

A new study provides us with a better understanding of how the brain responds to injuries. Researchers have discovered that a protein called Snail plays a key role in coordinating the response of brain cells after an injury.
