Document Summary
Specialization of reach function in human posterior parietal cortex (vesia) Introduction: ppc involved in visually guided reach, visuomotor function. Mips may be homologue of macaque mip of prr: medial-posterior cluster in superior parieto-occipital cortex (spoc) selectivity encodes contralateral pointing and reaching actions to peripheral locations; strongly activated during passive viewing of tools within graspable range. Spoc may be homologue to reach specific regions in monkey, which contains areas. Info may be integrated with goal info from. In eye and hand movements, eye movements precede the hand, with eye fixation normally anchored to a target until the end of the reach movement and improve their accuracy. If spoc is associated w/ reaches toward retinally peripheral targets (eye and hand decoupled) region has a more reach-specific function independent of gaze signals. If mips is more specialized for reach toward foveated targets gaze and reach signals intermingle here.
