Lateralized visual processing in standard and dichoptic viewing.

<p>In standard binocular viewing (left side), targets in the left visual field (green) are projected onto the right hemiretina (nasal or temporal) of both eyes and processed in the right hemisphere. Targets in the right hemifield (orange) are similarly processed in the left hemisphere. Each hemisphere, therefore, receives information from both eyes via ipsilateral and contralateral connections. Under dichoptic viewing (right side), targets in the temporal hemifield of an eye (green) are projected onto the nasal hemiretina of that eye and processed in the contralateral hemisphere and targets in the nasal hemifield (orange) are projected onto the temporal hemiretina and processed in the ipsilateral hemisphere. Lateralized targets in a dichoptic viewing task are thus processed in one hemisphere only, which may change the typical course of visual processing.
