Try to look inside the brain, and you're not going to get very far. But photoacoustic imaging may be a solution for the shortcomings of conventional imaging. It uses lasers to make the brain sing.

Doctors tell surgical patients to get out of bed as soon as possible, but people with brain injuries are encouraged to rest. Now it looks like activity can benefit brain injured patients, too.

Researchers in Seattle are busy cataloging what scientists have learned. For now that includes detailed information on 240 mouse cells. Next up: a data trove of details on human brain cells.

No wonder the brain needs so much energy. The same coordinated activity that allows you to retrieve a specific memory, like what you had for breakfast, continues at rest and even during sleep.
