Pinky and the (lab-grown) Brain

Vox
About this episode

It’s not great to be a lab rat. And it turns out, lab rats might not be that great for science either. Could the future be little lab-grown brain clumps?

Guests: Rachel Nuwer, science journalist; Lisa Genzel, professor of neuroscience at Radboud University

This episode has been updated. An earlier version didn’t differentiate between two stages of drug development.
