The proposed project seeks to elucidate memory processes and consolidation during sleep by leveraging the unique capability of direct recordings from the human brain at multiple levels of resolution-single neurons, localized neuronal assemblies, intracranial local field potentials-during rich behavioral tasks with real-life narratives and extracting neural features that relate to different aspects of episodic experience. The investigators will further probe causal mechanisms of consolidation by application of auditory and electrical stimulations during sleep and its effect on modulating memory processes.

Recognition Accuracy
Timeframe: 1-2 days contained within the participants' 1-2 week hospital stay; Specifically for each experiment, the outcome measure will be computed during the pre- and post-sleep memory tasks
Recognition Discriminability (D-prime)
Timeframe: 1-2 days contained within the participants' 1-2 week hospital stay; Specifically for each experiment, the outcome measure will be computed during the pre- and post-sleep memory tasks.
