Monocular Focal Retinal Lesions Induce Short-term Topographic Plasticity in Adult Cat Visual Cortex

Calford, Mike B; Schmid, Leisa; Rosa, M


Electrophysiological recording in primary visual cortex (V1) was performed both prior to and in the hours immediately following the creation of a discrete retinal lesion in one eye with an argon laser. Lesion projection zones (LPZs; 21-64 mm2) were defined in the visual cortex by mapping the extent of the lesion onto the topographic representation in cortex. There was no effect on neuronal responses to the unlesioned eye or on its topographic representation. However, within hours of producing...[Show more]
