Reaction time on the spatial working memory measure. This figure represents the reaction time (in seconds; mean and error bar) on the spatial working memory task for the subjects for each condition, and by (a) correct or (b) incorrect trials. For correct and incorrect trials, reaction time was significantly longer in the ECS condition relative to baseline, MST, and sham. There were no other significant differences. ECS, Electroconvulsive shock; MST, magnetic seizure therapy; sham, anaesthesia only.
