SMA activity during the change-of-plan task.

Time–frequency plots for conventional averaged epochs after baseline correction (top row) and similar epochs generated using the convolution model (bottom row). The images are centred on the go signal (left), button press (centre) and change signal during a successful change response (right). The specific responses to closely overlapping events only emerged in the convolution analysis and were impossible to disambiguate from the epoched data alone.
