The long-loop reflex involved in the triggering of paroxysmal activities by proprioceptive afferents is examined in monkeys with a chronic alumina focus and in cats with an acute penicillin focus. Electrical stimulation of a tibial nerve in monkeys as well as muscle stretch in cats elicit a cortical 'evoked spike', i.e., an evoked potential followed by an epileptic spike, accompanied by one or two motor bursts in the muscles concerned. With a very small acute focus, this transcortical reflex is shown to be quite topical: muscles in the vicinity are not affected. Relationships between evoked spike and myoclonic jerk are examined and it is shown that motor efferents usually follow the pyramidal tract. The concept of a transcortical reflex of proprioceptive origin is discussed on the basis of data collected from these models.
我们在患有慢性氧化铝病灶的猴子和患有急性青霉素病灶的猫身上，研究了本体感觉传入神经触发阵发性活动所涉及的长环反射。对猴子的胫神经进行电刺激以及对猫的肌肉进行拉伸，都会引发皮层“诱发棘波”，即诱发电位之后跟随一个癫痫棘波，并伴有相关肌肉的一到两次运动爆发。在非常小的急性病灶情况下，这种经皮层反射显示出很强的局部性：附近的肌肉不受影响。我们研究了诱发棘波与肌阵挛性抽搐之间的关系，结果表明运动传出神经通常沿着锥体束走行。基于从这些模型收集的数据，讨论了本体感觉起源的经皮层反射的概念。
