Activity of fastigial neurons evoked by stimulation of pontine relay nuclei and sensorimotor region of the cerebral cortex was recorded intracellularly in anaesthetized cats. Orthodromic excitation and inhibition (rarely) occurred both in efferent and intranuclear neurons irrespective of their localization within the nucleus or the level of their background activity. The excitation occurred as single or repeated APs or synaptic depolarization of axodendritic type (slow EPSP or fast prepotentials). Latencies of monosynaptic activation of neurons imply afferent conduction via "fast" and mainly "slow" pontine fibers. Similarities in synaptic organization of cortico-pontine and ponto-fastigial projections as well as features of neurons activation described in literature and obtained in present study suggest common mechanisms of functioning for these links of cortico-ponto-fastigial system of the cat.
在麻醉猫中，细胞内记录了刺激脑桥中继核和大脑皮质感觉运动区所诱发的顶核神经元活动。无论传出神经元和核内神经元在核内的定位或其背景活动水平如何，均可发生顺向兴奋和抑制（很少见）。兴奋表现为单个或重复的动作电位，或轴突-树突型突触去极化（慢兴奋性突触后电位或快电位变化）。神经元单突触激活的潜伏期提示经“快”和主要是“慢”脑桥纤维的传入传导。皮质-脑桥和脑桥-顶核投射的突触组织相似性，以及文献中描述的和本研究中获得的神经元激活特征，提示猫皮质-脑桥-顶核系统这些连接的共同功能机制。
