Episode 22: The Neuroscience of Speech Production

Neuroscience: Amateur Hour

So this week’s episode is all about speech production. Speech is a fundamental way of communicating our needs, desires, threats, resources, etc to our conspecifics. But do you know about the circuits and muscles and brain regions responsible for our ability to physically produce speech?
