In intact or decerebrate pigeons, unilateral functional deafferentation of the dorsal neck muscles of one side produced a postural asymmetry, characterized by an increase in flexor tonus of the ipsilateral wing and leg and an increase in extensor tonus of the contralateral limbs. This postural asymmetry was just opposite in sign to that described recently in cats, where unilateral section of the cervical dorsal roots C1-C3 produced ipsilateral hypertonia and contralateral hypotonia of the limb extensors. The striking increase in flexor tonus of the wing following deafferentation of the ipsilateral neck extensors contrasts with the decrease in flexor tonus of the wing which occurs after deafferentation of the ipsilateral leg extensors. It appears, therefore, that the proprioceptive input from the neck and that from the leg extensors exert an antagonistic influence on the flexor tonus of the ipsilateral wing.
在完整或去大脑的鸽子中，一侧颈部背侧肌肉的单侧功能性传入神经阻滞会产生姿势不对称，其特征为同侧翅膀和腿部的屈肌紧张度增加，以及对侧肢体的伸肌紧张度增加。这种姿势不对称的体征与最近在猫身上所描述的恰好相反，在猫中，单侧切断颈背根C1 - C3会导致肢体伸肌的同侧张力亢进和对侧张力减退。同侧颈部伸肌传入神经阻滞后翅膀屈肌紧张度的显著增加，与同侧腿部伸肌传入神经阻滞后翅膀屈肌紧张度的降低形成对比。因此，似乎来自颈部和来自腿部伸肌的本体感觉输入对同侧翅膀的屈肌紧张度产生拮抗作用。
