Understanding and enhancing memory during sleep

Official title: Decoding and Selective Modulation of Human Memory During Awake/Sleep Cycles

Run by University of California, Los Angeles · NCT05452122 · Data updated 2026-11-12

This study is trying to see how sleep affects memory by recording brain activity in people with epilepsy and using sounds and electrical signals to see if they can improve memory.

Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are epilepsy patients aged 18 to 65 who require depth electrode placement for clinical reasons.

Probably not a fit

Patients with neurological or psychiatric conditions other than epilepsy may not benefit from this study.

What this trial studies

This project aims to explore how memory processes and consolidation occur during sleep by directly recording brain activity from patients with epilepsy. The study will utilize auditory and electrical stimulation during sleep to investigate their effects on memory modulation. By analyzing single neurons and localized neuronal assemblies, researchers hope to uncover neural features associated with episodic experiences. The findings could provide insights into the mechanisms of memory consolidation and potential therapeutic approaches.

Why it matters

Potential benefit: If successful, this study could lead to new methods for enhancing memory retention and learning through targeted stimulation during sleep.

How similar studies have gone: While the approach of using direct brain recordings and stimulation during sleep is innovative, similar studies have shown promise in understanding memory processes.
