Abstract:In order to increase cognitive functions, scientists are constantly trying to further develop techniques, such as the transcranial direct current stimulation (tDCS). This stimulation technique uses weak electrical currents to alter the action potential of neurons in the brain. One development in this area is the High-Definition tDCS (HD-tDCS) which allows for a higher focality that can lead to more concrete inferences about the specific area, explaining why it is frequently implemented nowadays. This is a convenient method since it does not require surgery and can therefore be used in different areas besides research, for example gaming. The stimulation can have different effects depending on the timing of administration, which can be designated as online or offline. Online stimulation describes administering the stimulation during a task while offline stimulation describes the stimulation administered before a task. In this study, the HD-tDCS method was used to stimulate participants’ (N = 26) right lower dorsolateral prefrontal cortex (rlDLPFC) to influence their visuospatial working memory before playing the Super Hexagon game. This was conducted with both anodal (excitatory) and cathodal (inhibitory) stimulation and included a sham condition.
