Abstract

Direction selectivity is a characteristic feature of neurons in the visualcortex of higher mammals. Excitatory and inhibitory cortical neurons receive different patterns of synaptic connections resulting in different receptive field properties. We have analyzed the direction tuning of excitatory and inhibitory neurons of ferret visual cortex using single unit recordings. Direction tuning was constant among neurons in a vertical column. The majority (>80%) of excitatory (regular spiking) neurons were direction tuned ordirection biased. Fast spiking (inhibitory) neurons were orientation. but only weakly or not direction tuned. This indicates that excitatory and inhibitory neurons have different functions in visual processing and their different integration in thalamocortical and intracortical circuits results in a diversification of receptive field properties.
