单侧损毁猫顶叶皮质的中丘上回会产生不对称的前庭-眼反射，因此对头部向病变对面旋转的反应会变得更弱。猫的单侧上丘损伤也会产生同样的效果。在任何一种情况下，对称反应都会在2-3周内恢复。根据单侧损害对用于指导个人外空间内行为的内部参照物的移位的结果进行了讨论。这一假设与男性单侧顶后病变后观察到的临床症状的相关性进行了讨论，特别强调了单侧忽视现象。
Unilateral lesions of the middle suprasylvian gyrus in the cat parietal cortex produce an asymmetrical vestibulo-ocular reflex such that responses to head rotation toward the side opposite to the lesion become weaker. Unilateral lesions of the superior colliculus in the cat also produce the same effect. In either case symmetrical responses are recovered within 2-3 wk. Results are discussed in terms of displacement, by the unilateral lesion, of an internal reference used for directing behavior within extrapersonal space. Relevance of this hypothesis to clinical symptoms observed in man after unilateral posterior parietal lesions is discussed, with particular emphasis on the unilateral neglect phenomenon.
