Effects of MPH on neuronal ensemble decoding of task-related information. A, Decoding accuracy of a SVM algorithm extracting single-trial information about the visual, attentional, and saccadic representations in the neuronal ensemble activity of simultaneously recorded neurons. Decoding accuracy, used as a proxy for neuronal coding accuracy, is presented as a function of drug dose (x-axis), as in preceding figures. The purple line represents the achieved chance performance using permutation testing and overlaps roughly with the theoretical chance performance of 25%. B, Same as A but for monkey “JL.” Error bars represent SEM.
