The internal structure of mitochondria with prismatic cristae in astrocytes of the inferior olivary nucleus of the adult cat was examined. The interior of the mitochondria with prismatic cristae cut in cross-section can be divided into 2 areas: (1) a peripheral, rather structureless area, and (2) a central, highly organized area. The former is composed of the inner mitochondrial membrane and a small number of peripheral cristae protruding from the membrane and scattered dots. The latter is composed of numerous prismatic cristae arranged in almost hexagonal spacing and many dots which probably represent the transverse configuration of filaments oriented parallel to the cristae embedded in the matrix. For future comparative analysis, various quantitative observations on the fine structure of the central, highly organized area are described and discussed.
