Human-like neural activity detected in lab-grown mini brains(1/2)

This image shows the initial formation of a cortical plate, with each color marking a different type of brain cell. Scientists have picked up electrical activity in pea-sized lab grown brains for the first time, paving the way to model neurological conditions and answer fundamental questions on how our gray matter develops. It's not clear whether the mini-brains are conscious--the team behind the breakthrough suspect they're not but can't say for sure--opening up a new ethical dimension to the area of research moving forward.
