In this episode, Matt delves into the curious and cautionary tale of Delta Sleep-Inducing Peptide (DSIP), once hailed as a potential miracle cure for insomnia. In the 1970s, researchers were on a quest for a single "somnogenic molecule" that could act as the brain's natural sleep switch. A Swiss team believed they had found it, isolating a peptide that appeared to rapidly induce deep, slow-wave sleep when injected into animals. This initial excitement led to bold claims and sparked decades of...

Matt explores the human capacity for echolocation this week, dismantling the myth that this "biological sonar" is exclusive to animals. Revealing how peer-reviewed research shows all human brains possess the neural hardware to "see" with sound, Matt explains the physics of how sound creates detailed acoustic maps of our environment and introduces the brain's remarkable plasticity, setting the stage for this incredible sensory adaptation. The episode features stories of pioneers like Daniel Ki...
