Abstract

In chronic experiments on dogs discharges were recorded in efferent fibers of the vagal and splanchnic nerves and gastric branches of the solar plexus in the form of slow low-voltage and rapid high-voltage potentials. Alimentary conditioning to a previously indifferent stimulus produced a clear efferent reaction expressed in an increased number of oscillations. The magnitude of efferent electrical responses in all the examined structures is dissimilar and depends on the nerve nature (sympathetic or parasympathetic). The greatest electric reactions occur in the vagal gastric pathways.

摘要

在对狗进行的慢性实验中,记录了迷走神经、内脏神经的传出纤维以及太阳神经丛胃支中的放电情况,其形式为缓慢的低电压和快速的高电压电位。对先前无意义刺激的食物性条件反射产生了明显的传出反应,表现为振荡次数增加。在所有检查结构中,传出电反应的幅度各不相同,且取决于神经性质(交感神经或副交感神经)。最大的电反应出现在迷走神经的胃通路中。
