Abstract

Sparse representation in sensory cortex has been well verified and its capability of yielding response properties of single neurons is also demonstrated. In order to improve sparse representation to be more neurally plausible, we reconsider several response properties of single neurons, especially the cross orientation suppression and surround suppression. A new sparse representation model using intracellular and extracellular neural mechanisms is presented. Simulation results of the presented model explain physiological observations very well.
