“I am sorry, but your brain suffers from avalanches” is a diagnosis that should be a thing. The cure should involve a St. Bernard digging neurons out from under piles of neurotransmitter. Unfortunately, everyone’s brain suffers from avalanches. Indeed I can safely diagnose anyone who does not suffer from avalanches as dead. (And you thought the barriers to graduate school were intellectual?).

An avalanche in the brain is basically a small, generally inconspicuous event that triggers a massive cascade of neuronal activity. These are observed to occur without any external triggers.
