Abstract
The reverse correlation method is a standard technique in visual neurophysiology<br>for analyzing spatiotemporal structure of linear receptive field of early visual neurons.<br>A new discrete-time reverse-correlation technique for the study of visual neurons was<br> proposed to measure orientation and spatial frequency tuning of early visual neurons,<br>the so-called subspace-reverse-correlation method. It was shown that if the neuron can<br> be modeled as a spatiotemporal linear filter followed by a static nonlinearity, the cross-<br>correlation between the stimulus sequence and the cell’s spike train output gives the<br> projection of the receptive field onto the subspace of frequency space. Several advan-<br>tages of the subspace-reverse-correlation method over standard white-noise techniques<br> were reported. In this paper, I show the application of this method to psychophysics<br>,especially for measuring spatial frequency tuning of human perception. Furthermore,<br>I show that this technique will be applicable and useful for wide variety of cognitive<br> science research.A possible problems of subspace-reverse-correlation method are also<br>discussed.
