Spatio-temporal mapping of motor preparation for self-paced saccades

► MRCPs and cortical sources during self-paced saccades were studied. ► Contralateral IPS, SEF, and FEF were activated during short-fixation saccades. ► Ipsilateral IPS was also activated during long-fixation saccades. ► Amplitude and timing of BP are influenced by task demand in eyes and limbs movements.
