Ipsilateral ECoG 3D Reach Study

Description:

The purpose of this study was to explore the ipsilesional electrocorticographic (ECoG) correlates of three dimensional ipsilateral reaching movements in human subjects with cortical lesions over sensorimotor areas. The three subjects were seated in a chair and outfitted with infrared optical markers synchronously recorded with the ECoG data. They made reaches with their ipsilateral arm to touch the tip of a wooden dowel. This dowel was moved in front of the subjects by an experimenter in an attempt to thoroughly probe the 3D space in front of the subjects. When a subject successfully touched the dowel, they returned their hand to a comfortable resting position on their lap.
