Neurons in the lumbar sympathetic ganglion of the bullfrog were found to respond to presynaptic stimulation with rapid mechanical changes. These changes represent swelling of the presynaptic nerve terminals, followed by swelling of the somas of the postsynaptic neurons. After complete blockade of impulse transmission with D-tubocurarine, swelling of the neurons associated with the excitatory postsynaptic potential is observed.
研究发现，牛蛙腰交感神经节中的神经元会对突触前刺激产生快速的机械变化反应。这些变化表现为突触前神经末梢肿胀，随后是突触后神经元胞体肿胀。在用筒箭毒碱完全阻断冲动传递后，观察到与兴奋性突触后电位相关的神经元肿胀。
