||Stimultaneous recording from 21 electrode sites in a 4x4 mm area over the posterior cortex was used to determine the surface distribution of all major peaks which constitute flash evoked potentials (FEPs) and pattern reversal evoked potentials (PREPs) in hooded rats. Topographical maps were constructed with respect to bregma and midline reference points. The data indicate that not all of the peaks which constitute either evoked potentials have their greatest amplitude within the classically defined primary visual cortex. Further, since the FEPs were produced by uniform stimulation, the data suggest that surface regions of the rat visual cortex differ in ways other than simply the portion of the visual field from which information is received.
