Abstract Single neurons in visual cortex provide unreliable measurements of visual features due to … WebFeb 18, 2000 · Abstract. Theoretical studies suggest that primary visual cortex (area V1) uses a sparse code to efficiently represent natural scenes. This issue was investigated by recording from V1 neurons in awake behaving macaques during both free viewing of natural scenes and conditions simulating natural vision. Stimulation of the nonclassical receptive ...
