Neurological Correlates of Damage to the Magnocellular and Parvocellular Visual Pathways

Preview

Visual processing is divided into two pathways: the magnocellular pathway and the parvocellular pathway. One is concerned with motion and spatial analysis, the other with form and color perception. This chapter discusses the impairment in motion direction discrimination, particularly in the said pathways, of patients with unilateral cerebral hemispheric lesions. Such a condition causes impaired perception as well.

Keywords: magnetoencephalography; functional imaging; form perception; motion direction; motion-defined form
