tDCS and tACS laboratories

Transcranial direct current stimulation (tDCs) is a minimally invasive method to modulate ongoing brain activity in humans. Small, milliampere-level electric current is fed to the scalp using two electrode pads, anodal and cathodal. The modulatory effect is localised below and between the two electrodes.
tDCS and tACS laboratories

JYU currently provides access to three sets of tDCS equipment, at the EEG recording suites in the Kärki building. The same devices can be used to provide transcranial alternating current stimulation (tACS), a method to modulate brain activation in a rhythmic fashion to tap into the oscillatory phenomena in the cortical networks.
