About this episode
This episode explores the significant roles of astrocytes in brain function, challenging the traditional view that neurons are the sole drivers of mental processes.
We tend to think of neurons as the sole engine of our thoughts, emotions, and everything in between. For decades, a group of large brain cells called astrocytes have been thought of as mere packing peanuts for the brain. But new research suggests otherwise. On this episode of The Quanta Podcast, host Samir Patel speaks with writer Ingrid Wickelgren about these big cells’ big responsibilities, which include controlling brain states like hopelessness, sleep, and hunger. This topic was covered in a recent story for Quanta Magazine. Each week on The Quanta Podcast, Quanta Magazine editor in chief Samir Patel speaks with the people behind the award-winning publication to navigate through some of the most important and mind-expanding questions in science and math.
