(A) Brain regions involved in overcoming residual inhibition of a recently performed task were overlaid onto a 3D rendered brain (contrast ABA > ABC for the third task). Activation was found in the right lateral PFC, the visual word form area, and the occipital cortex. (B Left) Location of the right lateral prefrontal region (BA 45; Talairach coordinates x,y,z = 38,19,11, Z = 3.9 and BA 9/46, x,y,z = 27,27,27, Z = 4.2) displaying greater activity when subjects switch to a task that has recently been performed as compared to switching to a task less recently performed. (Right) Averaged time series data for the group at the peak of the right lateral PFC for the ABA and ABC trials. (C) Location of the visual word form area (x,y,z = −42,−53,−11, Z = 5.3) displaying greater activity in the contrast ABA > ABC.
