Phasic electrodermal responses after visual stimulation in the cortically blind hemifield.
Phasic electrodermal responses were recorded after presenting targets within the blind part of the visual field to patients with damage to the geniculostriate pathway. The results suggest that the electrodermal component of the orienting response can also be elicited after damage to the visual cortex. The electrodermal responses are interpreted in terms of registration of a visual stimulus. This registration seems to be mediated by extrastriate pathways.
