From: A case of polymicrogyria in macaque monkey: impact on anatomy and function of the motor system
Behavior: reach and grasp drawer task. Panel A: Reaction times (RT) for each hands in the behavioral unimanual tasks for the 4 monkeys involved in the behavioral reach and grasp drawer task. In each case, the hand with which the PMG monkey (Mk-PM) exhibited the shortest average RTs (right) has been statistically tested against the fastest hand of the 3 normal monkeys (Mk-IU, Mk-I4, Mk-I5) using a Mann-Whitney test. Panel B: Movement times corresponding to the following movement components: First reaching time: from 'hand movement onset' to 'touch knob', Pulling time: from 'touch knob' to 'drawer fully open', Second reaching time: from 'grasping hand movement onset' to 'enter drawer's well', Grasping time: from 'hand penetrating in the well' to 'hand out of the well'.
