Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Anodal stimulation
Participants in the active stimulation group will undergo anodal transcranial direct current stimulation (tDCS). tDCS will be delivered by a battery-driven, constant-current stimulator connected to two saline-soaked surface sponge electrodes. An anodal electrode (25cm2) will be placed over the ventromedial prefrontal cortex and one cathodal electrode (35cm2) will be placed over the occipital cortex. Scalp electrodes will be positioned according to the 10-20 EEG international system. A current of 2mA will be applied for 20 minutes and the current will be ramped up and down over 30 seconds at the beginning and end of the stimulation period.
Transcranial direct current stimulation
Non-invasive stimulation will be conducted using a tDCS device (StarStim, Neuroelectrics, Spain).
Sham stimulation
The sham tDCS condition will involve the same placement of the electrodes, current intensity, and ramp-up/down time as the active tDCS condition, but stimulation will only last for 30 seconds.
Sham transcranial direct current stimulation
The same device will be used as in the active stimulation group, but stimulation will be terminated after 30 seconds.
