Scientists have discovered a neural network that fires up just when you're trying to fall asleep. Why does the mind speed up when the body needs to rest? In this episode, we explain the resting-state network, discovered by Marcus Raichle, and how it turns silence into an internal monologue. We'll see how rumination, described by Susan Nolen-Hoeksema, takes over the brain at night, and why the stress axis responds with a surge of cortisol even to imagined threats. We'll explore Matthew Walker's research on prefrontal cortex weakening, Bonnet and Aranda's hyperarousal model, and Arthur Spielman's three Ps model. We'll also dispel myths that actually make insomnia worse. Take a step-by-step walk through the neurobiology of sleepless nights. 🧩 SERIES: Why Do You Feel That Way?
