Reach plans in eye-centered coordinates.

摘要: The neural events associated with visually guided reaching begin an image on the retina and end impulses to muscles. In between, a plan is formed. This could be in coordinates of arm, specifying direction amplitude movement, or it eye because visual information initially gathered this reference frame. reach-planning area posterior parietal cortex, activity was found more consistent eye-centered than arm-centered coding reach targets. Coding arm movements frame advantageous obstacles that affect planning as well errors are registered Also, planned coordinates, use similar for may facilitate hand-eye coordination.
