  • Title: Orientational and directional selectivities of visual neurons in the superior colliculus of the cat.
    Author: Li B, Wang L, Wang Y, Diao Y.
    Journal: Sci China C Life Sci; 1996 Apr; 39(2):123-32. PubMed ID: 8760460.
    Abstract:
    Based on quantitative analyses of the response characteristics of visual neurons in the superior colliculus to moving optical bar stimuli, it is demonstrated for the first time that the visual neurons in superior colliculus of the cat have, to some extent, orientational selectivity. The significance of this selectivity is discussed in reference to its morphological substrate and physiological functions. In addition, both the directional and orientational selectivities in the superior colliculus are relatively weak when compared with those in the primary visual cortex, and the majority of the neurons prefer upward or downward motion in the visual field.
