Establishing Concurrent Transcranial Alternating Current Stimulation and Electroencephalography for Recording Human Brain Activity

Source: Fehér, K. D. et. al., Concurrent Electroencephalography Recording During Transcranial Alternating Current Stimulation (tACS). J. Vis. Exp. (2016)This video demonstrates the setup of concurrent transcranial alternating current stimulation (tACS) and electroencephalography (EEG) experiments to deliver rhythmic electrical signals to the brain while recording brain activity. The procedure ensures electrode isolation and prevents gel bridging for accurate stimulation and clean EEG signals.
