The Down State Forgets

Adaptation Recovery Decides the Initiating Layer of the Slow Oscillation Only When Down States Are Short

A paper from the School of Underlying Conditions runs a three-layer rate model of a cortical column through the slow oscillation and asks whether layer 5 leads the column into each up state because it is the most excitable layer or because it recovers soonest from adaptation. When down states are long, the share of up states initiated in layer 5 depends on its excitability alone; when they shorten to one to three seconds, slow layer-5 recovery cuts that share from 59% to 32% at matched excitability.
