Sentence examples for color selectivity from inspiring English sources
One obvious limitation of using fMRI to study color selectivity in early visual cortex is the lack of a clear correspondence between color-selective BOLD responses and the supra-threshold performance in color perception.
The preferred color and the strength and sharpness of the color selectivity differed from cell to cell. Figure 5 shows the responses of 8 representative color-selective neurons.
In this work, we address the problem of understanding the cortical processing of color information with a possible mechanism of the development of the patchy distribution of color selectivity via computational modeling.
At lower levels, in the retina and in the geniculate, cells in these two subdivisions differ in their color selectivity, contrast sensitivity, temporal properties, and spatial resolution.
Neurons in motion processing areas MT and MST have been shown to have no color selectivity.
Visual processing of color is well understood from cones in the retina through ventral stream color selectivity via the parvocellular pathway [1].
Presumably, the PITC contains a number of columns, but how the neurons with different color selectivities are spatially arranged within the PITC still remains unclear and awaits more detailed mapping.
The color-selectivity indices for these neurons were all larger than 0.6 (1.0,, 1.0, and 1.47 for A– C, respectively), and they all showed statistically significant response variation across colors (ANOVA, P < 0.05).
To test the color (shape) selectivity, the shape (color) of the stimuli was fixed to the optimum parameters for the neuron under study.
Within the PITC, we also found that color-selective neurons with and without shape selectivity were intermingled, which suggests that the processing of color and shape information are closely related in the PIT.
Green color indicate less selectivity, whereas blue color indicates more selectivity in favor of CAII Fig. 12 The cloud view maps the similarities of the molecules w.r.t. the three pKi values to a 2D space so as to molecules with similar pKi values are adjacent.
