Figure 4.
Comparison between results obtained in experiments 1 and 2 for the common delays, comparing the results obtained when subjects were planning a leftward movement with vision (Light) or when blindfolded (Dark). A late peak of facilitation at 125 ms for the PPC–M1hand interaction was evident only when subjects were able to see the peripheral targets. *p < 0.05, post hoc analysis. Errors bars indicate SEM. Note that significant facilitation (relative to the 100% baseline) was observed for both the light and the blindfolded condition at the early 50 ms delay.
