N2 - Background: It is known that ventral premotor cortex responds selectively to the visual perception of object shapes. However, it is unclear whether this activation also contributes to visual processing. Objective: In this study we want to assess whether activation in premotor areas contributes to visual perception of objects.Methods: We measure performance on a perception task while delivering single pulse transcranial magnetic stimulation (TMS) to the left premotor cortex at different latencies after stimulus onset. Results: We show that in cases of limited visual consciousness, disturbing the left premotor cortex 150 ms after stimulus onset results in a decrease in the capacity to recognize shapes, compared both to other latencies and to stimulation of the vertex. Conclusion: Premotor cortex plays a constitutive role in object shape recognition.
