Summary

\*\*Follow-up Control Study for Creativity Study

Purpose: To investigate the effect of transcranial alternating current stimulation (tACS), a form of noninvasive brain stimulation, in healthy subjects. This experiment is a follow-up to previous tACS studies that used a creativity assessment.

Participants: 35 males and females, at least 18 years of age, without history of major psychiatric/neurological disease or associated medication use, or prior brain surgery/implants.

Procedures (methods): This is a cross-over study design. Participants will undergo a control condition of stimulation (sham or individual alpha, 8-12 Hz, tACS) during electroencephalogram recordings. In addition, pupil diameter, heart rate, and respiration will be measured continuously. This is to study the physiological effects of stimulation.

Interventions

OTHER

NeuroConn Plus Stimulator tACS

Transcranial alternating current stimulation (tACS) is a novel, noninvasive brain stimulation approach in which weak electric currents are applied to the scalp. The electric currents that are applied to the scalp are in a sine-wave pattern.

OTHER

NeuroConn Plus Stimulator Sham

For sham stimulation, the participant receives up to 1 minute of tACS stimulation until the stimulation fades. This mimics the same skin sensations that a participant would experience during a tACS session.
