HD-tACS (invented at CCNY Neural Engineering) shows to boost memory in adults (NBC, BBC, Nature...)

High-Definition transcranial Alternating Current (HD-tDCS) was invented by the Neural Engineering group at The City College of New York, and licensed to Soterix Medical as part of the High-Definition non-invasive brain stimulation platform.

A recent publication in Nature Neuroscience by Rob Reinhart of Boston University shows that HD-tACS can boost memory in older adults. The work has been features in news from MIT Tech Review (which interviewed Dr. Bikson), NBC, BBC , the Wall Street Journal, and others.

HD-tACS is the only technology capable of delivering sinusoidal waveform stimulation to targeted brain regions. Other technologies cannot do this, for example invasive (implanted) devices cannot safely deliver sinusoidal currents, non-invasive approaches like Transcranial Magnetic Stimulation cannot technically deliver sinusoidal fields, and tradition tACS is not focal. The unique capability of HD-tACS was critical to the targeted outcomes reported by Reinhart et al. study.
