Role of burst activity in attribute detection by visual neurons of the cat cortex

The temporal structure of neuronal responses has been investigated in the Clare-Bishop area of the cat cortex. Stationary and moving slit and moving spot have been used for stimulation. It was found that orientational and directional selectivity was determined mainly by the number of clustered impulses and the number of clusters. A closed-loop model for features detection which is able to interpret clustered activity is presented.
