Characterizing a simulated population of 300 foveal V1 neurons. A, The goodness-of-fit R² criteria for Gabor fitting in the left and the right eye. Each dot represents a neuron, while the filled color indicates the quantity R_max² = max{R_left², R_right²}, a measure of how well a Gabor function describes the receptive field regardless of whether the neuron is monocular or binocular. B, Neurons from normal (red dots) and amblyopic (blue dots) populations trained on foveal stimuli (for more details, see Materials and Methods). C, The orientation parameter for Gabors fitted to the left and the right eye receptive fields. Only neurons with binocular receptive fields defined by the criterion min{R_left², R_right²} ≥ 0.5 are shown. Note that the range of the angles is [0°, 180°], with 0° being the same as 180°. D, DTCs for the binocular neurons from C were estimated by the binocular cross-correlation of the receptive fields of the left and right eyes under horizontal displacement. Gabors were fitted to the resulting curves, thereby giving a measure of the position and phase disparity in the receptive fields (Prince et al., 2002a,b). This figure shows the position disparity plotted against the relative phase disparity. It also shows the histograms for the two types of disparities.
