Pea-size clusters of human cells called brain organoids inspire both hope and fear. Experts are debating how scientists can ...

The next time you reach for a memory or make a quick choice, a storm of tiny signals races through your brain. Scientists can ...

Most of the time, you assume your brain is either “on” or “off,” awake or asleep. A new study shows something far more ...

Researchers have built a tiny, lightweight microscope that captures neuron activity with unprecedented speed that can be used in freely moving animals. The new tool could give scientists a more ...

Using advanced microscopes that capture brain cell anatomy and activity, a portion of a mouse's brain was mapped and rendered into a 3D atlas that creates new possibilities for neuroscience. When you ...

This color-coded graphic shows different populations of cells in the mouse brain, each one targeted by one of the genetic tools developed by scientists at the Allen Institute and other institutions.

Scientists have uncovered how aging alters tryptophan metabolism in the brain, linking a longevity protein to ...

Neuroscientists have long listened to the brain’s electrical spikes, but those loud crackles are only the final output of a much quieter conversation. Now a set of new tools is letting researchers ...

Pulsing ultrasound waves through the brain could improve survival after a type of stroke by helping to clear out inflammatory dead blood cells, according to a study in mice. The approach, which ...

A vanishingly rare genetic glitch in a single enzyme can erase a newborn’s brain cells in a matter of weeks, leaving doctors with almost no way to intervene. Researchers have now traced that ...
