Visual stimuli and evoked responses in the rat.
Rats were presented with a series of visual stimuli, each described by shape, size, and position. Cortical recordings were made in medial and lateral positions of rat visual cortex. Average responses were calculated and correlated. This analysis revealed that information regarding size was contained in electrical activity from medial areas, and informtion regarding shape in electrical activity from lateral areas.
