NROC64H3 Lecture Notes - Lecture 11: Intraparietal Sulcus, Parietal Lobe, Saccade
Document Summary
The control of reaching requires three component processes: 1. A goal for the action must be selected and maintained a process closely linked to selective attention. To properly reach, need to choose what want to reach = make that goal a reality: 2. Visuospatial information relevant to this goal must be acquired and translated into a motor programme. The trajectory to get to bottle and grasp needed to (for example) hold: 3. A sequence of actions needs to be planned and executed: need to move hand and muscles and enough force. Involved in several aspects of the early transformations for visually guided reach. Intraparietal sulcus involved in: planning of reaching movements toward objects (posteromedial region) Integrating grasp-related information about an object (anterolateral portion) There are some regions in reaching, saccades, grasping: aip in grasping, lip in saccades, some overlap in involvement ag is in both reach and saccade simultaneously.
