Abstract

Young¹ first proposed the Gaussian derivative and DOOG (difference-of-offset-gaussians) models to describe the 2-D spatial structure of visual simple cell receptive fields in primate cortex. The Gabor model has also been proposed to describe such physiological data. Although tests of all three models have previously been made for neural 1-D spatial frequency tuning curves,¹ I now report preliminary tests on recent 2-D cortical visual receptive field data measured directly in the spatial domain.² I also report on the effects of the temporal dimension on the fits of these models. This study was undertaken in collaboration with L. Jacobson, J. Gaska, H.-W. Chen, and D. Pollen at the University of Massachusetts Medical Center, who kindly provided the monkey cortical receptive field data.
