Abnormal global processing along the dorsal visual pathway in autism: a possible mechanism for weak visuospatial coherence?

abstract：:This paper reviews the role of vision in controlling pointing and reaching movements in man. Studies of visuomotor behaviour in normal subjects allow the identification of several levels for describing organization of visuomotor control. The relative contribution of central (programming) and peripheral (feedback) mech...
