Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Active HD-tDCS
Participants in the active arm will receive 20 min of real High-Definition transcranial direct current stimulation. Additional ramp-up and ramp-down phases at the beginning and the end of stimulation will last for 30 s.
Active High-Definition Transcranial Direct Current Stimulation (HD-tDCS)
Portable multi-channel tES stimulation (Starstim 8, Neuroelectric, Barcelona, Spain) will be used.
Sham HD-tDCS
During the sham session, the montage will be identical, however, the current amplitude will ramp up for 30 seconds, and for the remaining stimulation time, the current flow will terminate and will be kept to zero. Ramp-down phase at the end of stimulation will last for 30 s.
Sham High-Definition Transcranial Direct Current Stimulation (HD-tDCS)
Portable multi-channel tES stimulation (Starstim 8, Neuroelectric, Barcelona, Spain) will be used.
