The degeneration-Golgi-electron microscopy technique was used to study the termination of olfactory afferents in the entorhinal area (EA) in the rat. Following resection of the olfactory bulb, degenerating axon terminals can be observed in a superficial lamina of layer I of both medial (MEA) and lateral (LEA) part of EA. Twenty-one Golgi-impregnated cells of 7 neuronal types located in LEA were investigated with the electron microscope. Of these cells, two layer II spinous multipolar neurons and one layer III spinous pyramidal cell, all located in the ventral part of LEA (VLEA), and one layer II sparsely spined multipolar cell, located in the dorsal part of LEA (DLEA), were observed to form synaptic contact with degenerating axon terminals. Based on these findings the possibility of a 3-member neuronal chain is discussed: mitral cell of the olfactory bulb - layer II or III neuron of EA-CA3 cell or granule cell in the hippocampus.
运用变性-高尔基-电子显微镜技术研究大鼠内嗅区（EA）中嗅觉传入纤维的终末。切除嗅球后，在内嗅区内侧部分（MEA）和外侧部分（LEA）的I层浅表层可观察到变性的轴突终末。用电子显微镜研究了位于LEA的7种神经元类型的21个经高尔基浸染的细胞。在这些细胞中，观察到两个位于LEA腹侧部分（VLEA）的II层棘状多极神经元和一个III层棘状锥体细胞，以及一个位于LEA背侧部分（DLEA）的II层稀疏棘状多极细胞与变性的轴突终末形成突触联系。基于这些发现，讨论了由嗅球的二尖瓣细胞-EA的II层或III层神经元-海马体的CA3细胞或颗粒细胞组成的三神经元链的可能性。
