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