  Intracranial recordings in epilepsy patients are increasingly utilized to
gain insight into the electrophysiological mechanisms of human cognition. There
are currently several practical limitations to conducting research with these
patients, including patient and researcher availability and the cognitive
abilities of patients, which limit the amount of task-related data that can be
collected. Prior studies have synchronized clinical audio, video, and neural
recordings to understand naturalistic behaviors, but these recordings are
centered on the patient to understand their seizure semiology and thus do not
capture and synchronize audiovisual stimuli from tasks. Here, we describe a
platform for cognitive monitoring of neurosurgical patients during their
hospitalization that benefits both patients and researchers alike. We provide
the full specifications for this system and describe some example use cases in
perception, memory, and sleep research. Our system opens up new avenues to
collect more data per patient using real-world tasks, affording new
possibilities to conduct longitudinal studies of the electrophysiological basis
of human cognition under naturalistic conditions.
