The teenage brain isn't defective. It's optimized for something entirely different than adult cognition — and once you understand what, the chaos makes perfect sense. The prefrontal cortex — the adult executive brain — is one of the last regions to fully myelinate. Myelination is the brain's insulation process that speeds up neural signaling. For most people, it's not complete until the mid-20s. But here's what's counterintuitive: while the prefrontal cortex is still under construction, the limbic system — particularly the amygdala — is already fully online. This means teenage brains feel emotions at full intensity, before the reasoning hardware is ready to modulate them. The result? A brain that's basically: - Emotion: 100% - Regulation: ~60% This isn't a bug. It's an evolutionary feature. Adolescence is when humans develop independence, take risks, and form identity.…
