Figure 2.

Results of the visual nontemporal tasks. Average (SEM indicated) of individual discrimination thresholds for V1 and V5/MT paired-pulse TMS at the three different delays (different shades of blue and red for V1 and V5/MT, respectively) after either interval onset (encoding) or offset (working memory). Top, Thresholds are indexed as the change with respect to the vertex stimulation (i.e., average of the two vertex blocks) as follows: site-vertex/vertex. Bottom, Averaged thresholds not normalized to the vertex; gray and white bar are, respectively, the vertex and no-TMS condition.
