The parietal reach region is limb specific and not involved in eye-hand coordination.
Primates frequently reach toward visual targets. Neurons in early visual areas respond to stimuli in the contralateral visual hemifield and without regard to which limb will be used to reach toward that target. In contrast, neurons in motor areas typically respond when reaches are performed using the contralateral limb and with minimal regard to the visuospatial location of the target. The pari...
متن کاملLesions of cortical area LIP affect reach onset only when the reach is accompanied by a saccade, revealing an active eye-hand coordination circuit.
The circuits that drive visually guided eye and arm movements transform generic visual inputs into effector-specific motor commands. As part of the effort to elucidate these circuits, the primate lateral intraparietal area (LIP) has been interpreted as a priority map for saccades (oculomotor-specific) or a salience map of space (not effector-specific). It has also been proposed as a locus for e...
متن کاملMovement order and saccade direction affect a common measure of eye-hand coordination in bimanual reaching.
Studies of visually guided unimanual reaching have established that a saccade usually precedes each reach and that the reaction times (RTs) for the saccade and reach are highly correlated. The correlation of eye and hand RT is commonly taken as a measure of eye-hand coordination and is thought to assist visuospatial guidance of the hand. We asked what happens during a bimanual reach task. As wi...
متن کاملEye-hand coordination: saccades are faster when accompanied by a coordinated arm movement.
When primates reach for an object, they very often direct an eye movement toward the object as well. This pattern of directing both eye and limb movements to the same object appears to be fundamental to eye-hand coordination. We investigated interactions between saccades and reaching movements in a rhesus monkey model system. The amplitude and peak velocity of isolated eye movements are positiv...
متن کاملThe Effect of Different Break Activities on Eye-Hand Coordination in Female Students
People face breaks in their daily tasks that effect on their daily life. The present study was designed to evaluate the effect of different break activities on eye-hand coordination in female students. In the current experimental study conducted with repeated measures design, 36 high school female students with age range 13-15 years old were conveniently selected. In order to evaluate participa...
