Auszug

TMS über dem visuellen Kortex kann positive und negative Phänomene auslösen: Phosphene und visuelle Maskierung. Bereits im allerersten Kongressbeitrag zur TMS berichteten Barker et al. (1985) neben den positiven Effekten über dem motorischen Kortex (Auslösung eines motorisch evozierten Potenzials) auch über die Möglichkeit, durch okzipitale Stimulation die Wahrnehmung von Phosphenen zu erzeugen. Der erste Bericht zur Auslöschung visueller Wahrnehmung stammt von Amassian et al. (1989).
