🧠 Sleep & Memory Consolidation: Hypnogram Simulator

Hypnogram of a night's sleep stages (N1-N3, REM) driving declarative and procedural memory consolidation, comparing full sleep against early sleep deprivation.

⚙ Under the hood

A 2D hypnogram traces sleep stages (N1-N3, REM) across a realistic ~90-minute cycle structure while two memory-strength curves update live: declarative memory consolidates during deep N3 slow-wave sleep, procedural/emotional memory consolidates during REM. Toggle between a full 8-hour night and an early sleep-deprivation cutoff to compare next-morning memory strength, with the other scenario always shown as a dashed reference line.
