- Rooster61 1y agoI was thinking along the same lines, but bigger. Mitochondria don't "shut down" when we sleep. If they did, we would die very quickly. If anything, they produce quite a bit of energy during things like REM sleep and digestion. I'm sure I'm missing some subtle details about HOW they "rest", but from a 30000 ft view, it's puzzling.
- SalariedSlave 1y agoThe paper's core idea isn’t that all cells that use mitochondria need sleep, but rather: > In a specific subset of sleep-inducing neurons, mitochondrial electron leak builds up when energy is available but underused during neuronal inactivity. That mismatch acts as a sleep signal. The heart doesn’t fall into that subset.
