  • Title: [Relation between the spatial characteristics of the receptive fields of the superior colliculi of the cat and the rate of movement of a photic stimulus].
    Author: Kiseleva NB, Novikov GI, Podvigin NF.
    Journal: Fiziol Zh SSSR Im I M Sechenova; 1985 Dec; 71(12):1540-5. PubMed ID: 4092774.
    Abstract:
    The receptive fields of visual cells in superficial and intermediate layers of the cat superior colliculus were investigated: their boundaries, size, shape, dependence on the velocity of stimulus. The size of the excitatory zone decreased whereas the firing rate of the cells increased when the velocity 3 +/- 180 degrees.S-1 was changed. That was typical of both directionally and non-directionally selective cells. The mechanism of directional selectivity is discussed.
