[The structural-functional organization of the endoplasmic reticulum in the neurons of the rat cerebellar cortex].
Electron microscopic investigation of neuronal elements in the cerebellar cortex of rats revealed the existence of septal reticulum in axonal collaterals of Purkinje cells, in axons of basket cells and in mossy fibers. It was shown that this reticulum acts as a calcium depot. The presence in neuroplasm of the developed system of evenly distributed reticulum, which forms relatively isolated compartments and acts as the calcium depot may account for local regulation of rearrangements in the cytoskeleton. Wide presentation of the septal reticulum in the nervous cells of both invertebrates and vertebrates indicates functional determination of this structure.
