Extracellular osmiophilic oval bodies in the vagal and facial lobes of Carassius auratus (Teleostei-Cyprinidae).
During the study of ultrathins sections of the vagal lobes and the facial lobe of Carassius auratus (Teleostei Cyprinidae), by electron microscopy, extracellular oval or discoidal, very osmiophilic structures were found in the neuropil of the lobes. The structures measured approximately 73 nm long 58 nm wide, and 29 nm thick and were located within the extracellular spaces surrounding some glial and neural processes; they were closely apposed to the external membrane of these cells, sometimes forming a pavement like pattern. These structures, as far as we know, have not been previously described and their function is unknown.
