A modified model for dynamic properties of visual receptive field

摘要

The extended Gabor function model for visual receptive field (RF) was modified by substituting the term related to time with two-order integral kernel of Γ function to generate a new model called modified Gabor function model of RF. A set of the modified Gabor models (MGM) can present the major spatiotemporal properties of neuronal receptive fields at different levels of primary visual pathway. The transient responses, dynamic properties of RF simulat- de by MGM, are in good agreement with the observations in electrophysiological experiments
