Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is designed to investigate multitasking deficits, with a particular interest in reducing costs related to dual-tasking (dividing attention between tasks) and task-switching (switching between tasks) using noninvasive brain stimulation.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Active Stimulation

Active stimulation of targeted brain regions involved in task-switching and dual-tasking.

Group Type EXPERIMENTAL

Stimulation via noninvasive brain stimulation systems

Intervention Type OTHER

Active (at or below 2mA) stimulation targeting brain regions engaged in task-switching and dual-tasking for 30-40 minutes. Local IRB has determined the Soterix, Neuroelectrics, \& Halo devices to be non-significant risk (NSR) devices via abbreviated investigational device exemption (IDE) procedure.

Sham Stimulation

Sham stimulation of targeted brain regions involved in task-switching and dual-tasking.

Group Type SHAM_COMPARATOR

Stimulation via noninvasive brain stimulation systems

Intervention Type OTHER

Active (at or below 2mA) stimulation targeting brain regions engaged in task-switching and dual-tasking for 30-40 minutes. Local IRB has determined the Soterix, Neuroelectrics, \& Halo devices to be non-significant risk (NSR) devices via abbreviated investigational device exemption (IDE) procedure.
