The reactivity of neurones in the superior colliculi to the movement of the optic stimulus was studied in monocularly and binocularly deprived rabbits (MD and BD). Deprivation was effected by suturing the eyelids before the eyes opened. The neurones were classified into three groups by the degree of their directional selectivity (absolute, relative and zero). The effect of a prolonged (ten weeks or more) early MD consisted in the absence of collicular units with absolute selectivity. Proceeding from the existence of such units in the MD type rabbits in the third week of their life, it is suggested that prolongation of the MD time leads to their functional reduction. As the recorded characteristics of unit responses do not change in BD rabbits, it is assumed that the MD effect is not linked to limiting the function of vision and is just a consequence of a prolonged asymmetry of optic stimulation. The deprivation effect at the collicular level in different vertebrates is discussed.
在单眼和双眼剥夺的兔子（MD和BD）中，研究了上丘神经元对视刺激运动的反应性。剥夺是通过在眼睛睁开前缝合眼睑来实现的。根据神经元的方向选择性程度（绝对、相对和零）将其分为三组。长期（十周或更长时间）早期MD的影响在于不存在具有绝对选择性的丘单元。从MD型兔子在其生命第三周存在此类单元这一情况出发，表明MD时间的延长会导致其功能减退。由于在BD兔子中记录的单元反应特征没有变化，所以推测MD效应与视觉功能受限无关，只是视神经刺激长期不对称的结果。讨论了不同脊椎动物在丘水平的剥夺效应。
