The hemispheric lateralization of retrograde amnesia following unilateral electroconvulsive therapy (ECT) was measured by a novel nonverbal probe, the McCollough effect, which allowed equal and exclusive access to each hemisphere. Alternating exposure to perpendicular gratings of complementary colors (e.g., red vertical stripes alternated with green horizontal stripes) will cause subsequently presented black and white gratings to appear colored hours or even days later (the McCollough effect). Three of the patients examined (3 of 10) lost the effect in just the half visual field contralateral to the treatment side when unilateral nondominant ECT was interposed between the induction of the effect and the its test. Six patients lost the effect bilaterally following unilateral ECT. One patient retained a bilateral aftereffect. This patient had by far the shortest seizure (18 sec). Nine of 10 comparison patients, also suffering from major depression but without ECT intervening between induction and test, showed good bilateral retention of the McCollough effect. The remaining comparison patients showed no retention. These results imply that despite bilateral cortical spread of seizure activity, unilateral nondominant ECT has effects that are most pronounced over the stimulated hemisphere.
