The Complex Evolution of Brain Size and Intelligence in Mammals

Today, you’ll learn about the first ever total larynx transplant that gave one cancer patient his voice back, a new way to conduct gold-standard sleep studies without all the wires, and how a new discovery is changing the way scientists understand the mammalian brain.
