Inhibitory TMS over visual area V5/MT disrupts visual speech recognition

During face-to-face communication, the perception and recognition of facial movements can facilitate individuals’ understanding of what is said. Facial movements are a form of complex, biological motion. Separate neural pathways are thought to processing (i) simple, non-biological motion with an obligatory waypoint in the motion-sensitive middle temporal area (V5/MT) and (ii) complex, biological motion. Here, we present findings that challenge this dichotomy. Neuronavigated offline TMS over V5/MT on 24 participants (17 female and 7 male) led to increased response times in the recognition of simple, non-biological motion as well as visual speech recognition compared to TMS over the vertex, an active control region. TMS of area V5/MT also reduced practise effects on response times, that are typically observed in both visual speech and motion recognition tasks over time. Our findings provide first indication that area V5/MT causally influences the recognition of visual speech.
