Efficacy of Transcranial Electrical Stimulation (tES) on Emotion Processing

Transcranial alternating current stimulation (tACS) is a non-invasive neuromodulation technique of the brain with an AC micro-electrical stimulator, two rubber electrodes in saline-soaked sponges, and a control software to set the output of the stimulation type. Participants receive 20 min sessions of 1.5 mA alternating current delivered over the dorsolateral prefrontal cortex, for 7 consecutive days.

Transcranial direct current stimulation (tDCS) is a non- invasive neuromodulation technique of the brain with a DC micro-electrical stimulator, two rubber electrodes in saline-soaked sponges, and a control software to set the output of the stimulation type. Participants receive 20 min sessions of 1.5 mA direct current delivered over the dorsolateral prefrontal cortex, for 7 consecutive days.

Transcranial electrical stimulation (TES) is a non-invasive neuromodulation technique of the brain with micro-electrical stimulator, two rubber electrodes in saline-soaked sponges, and a control software to set the output of the stimulation type. Participants receive sham stimulation over the dorsolateral prefrontal cortex, with current turned off after 30 second. The session last 20 min for 7 consecutive days.
