[Response of lateral geniculate body neurons to moving light bands in cats].
A number of electrophysiological investigations revealed that the relief of activity (RA) arising in outputs of overlapping receptive fields (RFs) of the LGB reflects the form of test image. The RA was reconstructed by the responses of single neurons. The bars' width and velocity of their movement varied. Dependence of RA size on the image size was approximated with the aid of the logarithmic function for the small angle images (less than 1.5 +/- 2.0 angle degrees) and of the power function for larger sizes. The interrelationships obtained take place within the scope of motion rates from 0.6 to 30 angle degrees per second. This scope of motion depends on the eccentricity of RFs centers in respect to the area centralis.
