Conditions
Brief summary
The aim of the research project is to investigate whether the broad improvements seen across cognitive domains following tDCS in the healthy population are a result of general effects (i.e. improving speed of information processing) or specific effects (i.e. improving working memory capacity or social decision making ability).
Interventions
This is a randomised double-blind placebo-controlled within-subjects design. Participants will receive 20 minutes of either active or sham transcranial direct current stimulation (tDCS). Each participant will attend the Monash Alfred Psychiatry Research Centre on two occasions at least 72 hours apart.
Active tDCS will be delivered using electrodes placed within the Starstim system cap. The anode, or activating, electrode will be placed over F3 according to the 10-20 international system for EE
This is a randomised double-blind placebo-controlled within-subjects design. Participants will receive 20 minutes of either active or sham transcranial direct current stimulation (tDCS). Each participant will attend the Monash Alfred Psychiatry Research Centre on two occasions at least 72 hours apart. Active tDCS will be delivered using electrodes placed within the Starstim system cap. The anode, or activating, electrode will be placed over F3 according to the 10-20 international system for EEG placement, which has been determined to be an accurate estimate of the left DLPFC. The cathodal, or reference, electrode will be placed over the right supraorbital space. Stimulation will be applied at 0.028 ma/cm for 20mins. Sham tDCS is achieved by switching off stimulation after approx. 30s ; which occurs within the software of the Starstim system allowing for administrator and patient blinding.
