Reaching out: Cortical Mechanisms of Directed Action
Recordings from monkey cortex have demonstrated a sophisticated neural mechanism for the complex transformational mapping demanded by visually guided reaching.
متن کاملVisuomotor transformations: early cortical mechanisms of reaching.
Recent studies of visually guided reaching in monkeys support the hypothesis that the visuomotor transformations underlying arm movements to spatial targets involve a parallel mechanism that simultaneously engages functionally related frontal and parietal areas linked by reciprocal cortico-cortical connections. The neurons in these areas possess similar combinations of response properties. The ...
متن کاملCerebral cortical mechanisms of reaching movements.
Because reaching movements have a clear objective--to bring the hand to the spatial location of an object--they are well suited to study how the central nervous system plans a purposeful act from sensory input to motor output. Most models of movement planning propose a serial hierarchy of analytic steps. However, the central nervous system is organized into densely interconnected populations of...
متن کاملCortical mechanisms underlying the organization of goal-directed actions and mirror neuron-based action understanding.
Our understanding of the functions of motor system evolved remarkably in the last 20 years. This is the consequence not only of an increase in the amount of data on this system but especially of a paradigm shift in our conceptualization of it. Motor system is not considered anymore just a "producer" of movements, as it was in the past, but a system crucially involved in cognitive functions. In ...
متن کاملPointing out mechanisms underlying joint action.
Recent studies have shown that spatial and feature-based attention can contribute to inducing a spatial compatibility effect in both the standard Simon task and the joint Simon task. Less work generally has been devoted to investigating how attention modulates spatial compatibility effects. In the present study, we aimed to explore whether indirectly manipulating the degree of attention necessa...
