[Changes in the ratio of granular and agranular endoplasmic reticulum of the Mauthner neurons in fishes as an index of the compensatory processes during sensory stimulation].
Endoplasmic reticulum structure was studied on Mauthner neurons of adult fish and fry. Two-fold decrease of extension of rough endoplasmic reticulum components and similar increase of extension of smooth endoplasmic reticulum components were found to occur following long-term stimulation of Mauthner neurons. The significance of transformation of rough endoplasmic reticulum into smooth one as a result of neuronal compensatory response was discussed.
