The paper presents morphological evidence that upon deafferentation small Golgi cells and granule cells of the cerebellar cortex as well as geniculo-cortical relay cells of the Lateral Geniculate Nucleus develop presynaptic sites on their otherwise exclusively postsynaptic dendrites. The new synapses are, therefore, mostly dendro-dendritic, a logical consequence of the fact that in the absence of axonal sprouting in the two regions, the reactive synaptogenesis in the cerebellar cortex and LGN is accomplished by the participation of the (newly formed) presynaptic dendrites.
该论文提供了形态学证据,表明在去传入神经支配后,小脑皮质的小高尔基细胞和颗粒细胞以及外侧膝状体的膝状体-皮质中继细胞在其原本仅为突触后树突上形成了突触前位点。因此,新的突触大多是树突-树突型的,这是由于在这两个区域不存在轴突发芽的情况下,小脑皮质和外侧膝状体的反应性突触形成是通过(新形成的)突触前树突的参与来完成的,这是合乎逻辑的结果。
