“Temporal Interference Brain Stimulation”
The primary aim of this study is to translate temporal interference (TI) stimulation methodology into humans and examine its safety, feasibility, steerability, and focality. In the proposed early phase human experiment, the ability to apply TI stimulation will be assessed along spatial dimensions to selectively modulate neural activity and assess the feasibility of selective targeting deep brain structures without exciting overlaying cortex. The overall goal of the study is to advance TI methodology and its translation to humans. The specific aims in this study are to - Assess the safety of TI stimulation. - Assess the feasibility, focality, and steerability of TI stimulation by selectively modulating activity in subregions of a cortical area (calcarine cortex) It is hypothesized that TI stimulation can be used to impact different regions of the visual field that are represented within the calcarine fissure of the human brain. It is hypothesized that TI will be well tolerated by human subjects and side effects will be consistent with other forms of transcranial electric current stimulation (tES).
Device - Temporal Interference (TI) Stimulation
2-4 Temporal Interference stimulation sessions. The device is an experimental non-invasive electrical brain stimulator that functions similar to existing non-significant risk devices for electrical stimulation, including human non-invasive brain stimulation. Briefly, the device produces alternating current electrical stimulation in a kilohertz (kHz) range and results in less net charge applied within the brain. The device is powered by rechargeable 20 volt (V) battery (i.e. there is no connectio ...read more on ClinicalTrials.org
