Changes in Early Cortical Visual Processing Predict Enhanced Reactivity in Deaf Individuals
Figure 4
Brain responses to (a) peri-foveal and (b) peripheral targets.
Upper panels show ERPs at T5 and T6 electrodes for the targets. Lower panels show spatiotemporal distribution of the responses between 85 and 185 ms in each group. Like in the responses to the warning signal, the P1 component is prolonged in deaf compared to hearing subjects, whereas the N1 is similar.
