Event Abstract Back to Event On-line control of movement by posterior parietal cortex Alexandra Battaglia-Mayer1*, Philippe Archambault1 and Roberto Caminiti1 1 SAPIENZA - University of Rome, Department of Physiology & Pharmacology, Italy The cortical mechanisms for the control of hand movement trajectory were studied by recording cell activity in parietal area 5 of monkeys making direct reaches to visual targets and on-line corrections of movement trajectory, after unexpected change of target location in space. The activity of hand-related cells was influenced by different movement parameters, such as hand position, speed and movement direction. In parietal cortex the neural activity modulation mostly led, but also followed, the changes in hand kinematics. When a change of hand trajectory occurred, the pattern of activity associated with the movement to the first target evolved into that typical of the movement to the second one, thus following the corresponding variations of the hand kinematics. The visual signal concerning target location in space did not influence the firing activity associated with the direction of hand movement within the first 150 ms after target presentation. This might be the time necessary for the visuo-motor transformation underlying reaching in parietal cortex. Our studies suggest that on-line control of hand trajectory not only resides in the relationships between neural activity and kinematics, but, under specific circumstances, also on the coexistence of signals about current and future hand movement and direction.
