Caudato-nigral synaptic transmission was examined by stimulation of the caudate nucleus while recording from nigral neurons in cats recovering from circling movements induced by a unilateral circumscribed lesion in the substantia nigra pars reticulata after microinfusion of ibotenic acid. Extra- and intracellular recording from neurons in lesion-spared areas of the substantia nigra pars reticulata indicated that the caudato-nigral synaptic action on the side ipsilateral to the lesion exhibited a shorter duration of inhibition and a larger amplitude of excitation as a means of compensating for the circling movements.
在对经微注射鹅膏蕈氨酸后因黑质网状部单侧局限性损伤诱发转圈运动而正在恢复的猫，从黑质神经元记录时，通过刺激尾状核来检测尾状核 - 黑质突触传递。对黑质网状部损伤 spared 区域的神经元进行细胞外和细胞内记录表明，损伤同侧的尾状核 - 黑质突触作用表现出较短的抑制持续时间和较大的兴奋幅度，作为对转圈运动的一种补偿方式。 （注：“lesion-spared”直译为“损伤 spared”，这里“spared”可能是指未受损伤或幸免损伤的意思，但结合语境整体较难准确翻译通顺，可根据实际情况进一步优化表述。）
