Updating after split-brain experiments. A. Two versions of the double-step saccade task. In both versions, a monkey fixates on FP and two targets (T1, T2) are briefly flashed in the right visual hemifield. Thus both targets are represented in the left hemisphere. Green square: An eye movement to T1, causes the representation of T2 to remain in left hemisphere. Red square: An eye movement to T1, causes T2 to shift into the right hemisphere. B. After the forebrain commissure is severed, monkeys have difficulty localizing T2 when its representation crosses form one hemisphere to the other (red stippling). C. After some time, the monkeys recover their cross-hemisphere updating ability (red stippling). Replotted with permission from Berman et al., 2005.
