Six things you were told about your brain that turn out to be incomplete. One year into My BrainWise Coach, Phil Dixon and Cole Bastian revisit the claims they made with confidence and look honestly at where the science has moved. Being corrected is not a setback. It makes the picture more interesting, and it changes how you work.
You hear:
- Why Karl Friston's predictive processing framework replaces the computer model of the brain, and why you cannot think your way out of a pattern
- A 2025 Nature Communications paper from Mousley and colleagues mapping five phases of brain development with transitions at nine, 32, 66, and 83
- Why the shift at 32 is a reorganization rather than a peak followed by decline, and why your forties are your most contextually capable years
- How the default mode network handles memory consolidation, future simulation, and insight, and why high performers switch between networks more cleanly
- The precise version of the multitasking claim, and how skill automatization frees executive capacity for what matters
- Maiken Nedergaard's discovery of the glymphatic system, the brain's waste clearance mechanism that runs far more actively during sleep
- Where Iain McGilchrist's work on hemispheric attention holds up, where A.C. Grayling's critique lands, and how to use the distinction with humility
If this show changes how you think about your own brain, rate and review it wherever you listen. Follow @mybrainwisecoach on every platform for part two, six discoveries that were not even on the map.
