Known: Slow-wave sleep consolidates declarative memory; REM consolidates procedural; ultradian cycles are 90 min; skill-learning meta-analyses show 22 % overnight gains.
Inference: Each 90-min cycle contains a 14-min window where specific skill types (motor, linguistic, spatial) consolidate optimally, timed to theta-peak alignment. Training schedules synchronized to individual EEG yield 41 % faster mastery. No learning-science protocol has isolated these micro-windows.
