Primary

Measure	Time frame
Directly after and 24h after stimulation; completion of rating instrument: parametric attentional assessment based on Bundesen’s Theory of Visual Attention (TVA; Bundesen, 1990). (The assessed attentional parameters are: processing speed, visual short-term memory capacity, top-down control)	—

Secondary

Measure	Time frame
