Reaching and Grasping
p0010 According to a long standing idea, reaching movements are supported by the dorsomedial parietofrontal circuit consisting of the superior parietal lobule (SPL) and the dorsal premotor cortex (PMd), whereas grasping movements entail the dorsolateral parietofrontal network involving the inferior parietal lobule (IPL) and the ventral premotor cortex (PMv). Recently, however, this dichotomist ...
متن کاملReinforcement Learning for Robotic Reaching and Grasping
A reinforcement learning approach is used to train a neural controller to perform a robotic reaching task. Unlike supervised learning techniques, where the teacher must provide the correct sequence of motor actions, only an evaluation of the robot's performance is provided. From this limited information, the robot must discover the appropriate motor programs that best satisfy the teacher's eval...
متن کاملInternal models of reaching and grasping
One of the most distinguishing features of cognitive systems is the ability to predict the future course of actions and the results of ongoing behaviors, and in general to plan actions well in advance. Neuroscience has started examining the neural basis of these skills with behavioral or animal studies and it is now relatively well understood that the brain builds models of the physical world t...
متن کاملAttentional landscapes in reaching and grasping
It is well established that during the preparation and execution of goal-directed movements, perceptual processing is biased towards the goal. Most of the previous work on the relation between action and attention has focused on rather simple movements, such as single saccades or manual reaches towards a single target. Here we review recent behavioural and neurophysiological studies on manual a...
متن کاملObject motor representation and reaching-grasping control.
The following two competing hypotheses were tested in the present study. Is grasp guided by multiple representations of a single object, each of which codes a different grasp motor act according to the physical properties of that item? Conversely, is grasp guided by a single representation that codes all the possible affordances enabled by the object? Subjects reached different objects, but the...
