Humans and other mammals cycle through distinct sleep phases. One of them is easily recognized by the darting motion of the eyes behind closed lids, giving it its name: REM (rapid eye movement) sleep.

A body-wide imaging method recorded calcium communication from nearly every cell in a living larval zebrafish, revealing ...

How does the brain decide to approach others? Researchers have found that coordinated brain activity linked to social behavior begins seconds before movement starts. In a study using zebrafish, they ...

A new study published in Nature suggests that the neural foundations of spatial navigation—the brain's internal "GPS"—may have emerged far earlier in evolution than previously believed. The research, ...

Imagine spotting someone across the room at a party, then heading over to speak to them. According to new research, your brain could be rehearsing those actions in your head before you actually start ...

Scientists have captured the rapid spread of seizures across a living zebrafish brain in three dimensions, thanks to an ultra-fast light sheet fluorescence microscopy system developed at the ...
