By dissecting a cockroach ... yes, live on stage ... TED Fellow and neuroscientist Greg Gage shows how brains receive and deliver electric impulses -- and how legs can respond. This talk comes from the TED-Ed project.

Greg Gage: The cockroach beatbox

The cockroach beatbox

Unveiling the brain's complexities, the talk uses a cockroach to demonstrate neuronal communication via electrical impulses.

Connecting neuroscience to daily life, a beatbox rhythm animates a cockroach leg, illustrating muscles' response to electrical signals.

Exploring brain function through a cockroach's leg, a neuroscientist reveals how neurons use electricity to communicate.
