Continuous mapping of direction selectivity in the cat's visual cortex.
A new method is demonstrated for continuously mapping direction selectivity on complex cells in the cat's visual cortex. A large area random noise pattern which always covers the whole receptive field area is moved along a circular path. The average response histogram yields the cell's selectivity for stimulus direction directly and in much less time than the conventional methods.
