About this trial
This study is to find out whether a type of non-invasive electrical brain stimulation called temporal interference transcranial electrical stimulation (TI-TES) can temporarily change brain activity during sleep, especially sleep spindles (brain rhythms in the \~8-16 Hz range). Up to 24 healthy participants in Dane County, Wisconsin will be enrolled for 3 overnight study visits. Participants can expect to be on study for approximately 5 weeks, depending on scheduling availability.
