Figure 4.

Transitions between Gabor functions and corresponding changes in pulse profiles. The physiological correlate of these transitions was explored using a simple network model in which a cell integrates inhibitory and excitatory input. (A–C) Gabor functions emerge as a result of excitation (red) and inhibition (blue) in a network model. (D,E) Shape of Gabor filters from (A–C). (G–I) Preference for pulse patterns as derived from the Gabor filters in (D–F). Note that the nonlinearity used in (I) differs from the one in Figure 3N. See Figure 3 for calculation of preference profiles.
