Neural Representation of Simple Visual Stimuli

Abstract

<p>Activity of individual cells in the visual cortex of the cat was observed during patterned stimulation of the retina. Orientation and illumination of a simple light-dark stimulus were varied. Cells gave the same response to different stimuli, suggesting that 'place' theories of pattern recognition, theories based solely on 'which' cells are responding, are inadequate. It is suggested that stimuli are represented by the relative activity across several neurons.</p>
