An electrophysiological study has been made of the degeneration of the afferent axons of the lateral olfactory tract (L.O.T.) which give rise to excitatory synapses throughout the olfactory cortex. These fibres were severed by removing one or both olfactory bulbs. Evoked potentials were recorded from slices of olfactory cortex in vitro prepared at various times after bulbectomy. Up to 1.6 days later, all potentials were similar to those of the unoperated side. Between 1.6 and 1.8 days there was a complete loss of evoked potential from both L.O.T. axons and postsynaptic neurones, which occurred synchronously at all points along a 5-6 mm length of the tract.
已对外侧嗅束（L.O.T.）传入轴突的变性进行了电生理研究，这些轴突在整个嗅皮质形成兴奋性突触。通过切除一个或两个嗅球切断这些纤维。在切除嗅球后的不同时间制备体外嗅皮质切片，并记录诱发电位。在长达1.6天的时间里，所有电位都与未手术侧相似。在1.6天至1.8天之间，外侧嗅束轴突和突触后神经元的诱发电位完全丧失，这种丧失在该束5 - 6毫米长度的所有点上同步发生。
