Hippocampal-Neocortical Memory Transfer Model

Electrophysiological Sleep Spindle Oscillations & Long-Term Storage

1Daytime Waking: Sensory encoding in Hippocampus (Temporary Buffer)
2Slow-Wave Sleep (SWS): Coordinated slow oscillations & sleep spindles
3Synaptic dialogue: Memory traces transferred to Neocortex (Long-Term Storage)
4Sleep Fragmentation: Impairs synaptic stabilization & memory retention
