The goal of this clinical trial is to find out whether stimulating the brain with electrical current during naps can increase certain kinds of brain activity that happen during sleep and lead to improvements in mental fatigue. Participants will attend 2 study visits, each of which may last up to 4-5 hours. During these visits, participants will wear a high density electroencephalography (hdEEG) cap and take a nap.
This project aims to use transcranial electrical stimulation with temporal interference (TES-TI) to enhance the production of sleep slow waves, boosting the restorative power of sleep and mitigating cognitive impairment (mental fatigue) and its underlying cause (brain fatigue).
Inclusion Criteria: * Adults aged 18-75 of any gender identity * Self-reported non-restorative sleep, as measured by a REST-Q score * English-speaking (able to provide consent and complete questionnaires) * Capable of taking daytime naps * US Citizen Exclusion Criteria: * Any current or history of neurological disorders or acquired neurological disease (e.g. stroke, traumatic brain injury), including intracranial lesions * History of inpatient psychiatric hospitalization * History of head trauma resulting in prolonged loss of consciousness; or a history of \>3 grade I concussions * Current…
TES-TI uses specific electrode arrangement patterns to selectively stimulate the brain. Participants will wear an hdEEG (high density electroencephalography) cap which will allow intermittent periods of stimulation from TES-TI.
