Reference frames for reaching when decoupling eye and target position in depth and direction

摘要: Spatial representations in cortical areas involved reaching movements were traditionally studied a frontoparallel plane where the two-dimensional target location and movement direction only variables to consider neural computations. No studies so far have characterized reference frames for considering both depth directional signals. Here we recorded from single neurons of medial posterior parietal area V6A during task fixation point targets decoupled depth. We found prevalent mixed encoding position, with eye-centered spatiotopic differently balanced same neuron. Depth was stronger defining frame cells, while that cells. The predominant presence various typologies suggests signals are processed on basis flexible coordinate systems ensure optimal motor response.
