Analysis of the rate at which adaptation affects BOLD responses. The left column in A, B and C show the response averaged over subjects for the first 60 secs of BOLD response after the adaptation stimulus is first shown, for V1, V2 and V3, respectively. Black arrow indicates the time of initial response that is used to calculate contrast sensitivity shown in the right column (open black squares). The red arrow marks the end of the adaptation period. The open red circles in the right column plot the contrast sensitivity as the average response during the experiment.
