What Happens to Your Brain When You Die

Every movie shows death as a flatline: one beep, then nothing. Neuroscience tells a stranger story. When the heart stops, the brain doesn't simply switch off. In some studies it bursts into a wave of fast, synchronized gamma activity, then a slow "brain tsunami" sweeps across the cortex. And hearing may be one of the last things to go. Here's what researchers have actually measured in the dying brain, and what it means for the people sitting at the bedside. 🎯 YOUR TAKEAWAY: If you're ever with someone in their final moments, keep talking to them.
