Implication of Cognitive Reserve in Non-pharmacological Intervention Outcomes

Transcranial Alternating Current Stimulation (tACS) is a tool that administers a weak alternating current (in the range of 0.1 to 4 mA), most often with a sinusoidal waveform, between electrodes placed over target areas. This can entrain the subjacent neuronal networks favouring the firing at specific frequencies of interest, in certain cases, with effects outlasting the stimulation duration up to 70 min.
