Description

Yokoi's team at Hokkaido mapped the idle brain rhythms of medaka fish into distinct repeating states. 32 electrodes took field readings across the sleeping forebrain. 3-second slices of slow delta waves were compared by their matching patterns. Grouping distilled the stream into a handful of network states.

Some states hogged the time while others barely appeared. Back-to-back spells usually stayed in the same state, and shifts retraced known paths. Shuffled data dissolved this structure. Yokoi reads the pattern as self-ordering, echoing rest-state rules seen across vertebrate brains. No task drove the fish.
