RESUMO

Astrocytic mitochondria in the hypothalamic region of the adult hamster brain have been studied by electron microscopy. Mitochondria showing triangular prismatic cristae, as seen in transverse section, and other unusual forms of mitochondrial cristae, are described and illustrated. Such mitochondria occur primarily in the suprachiasmatic and paraventricular nuclei, especially in perivascular astrocytic processes. The possibility that these atypical mitochondria might develop a specific function is discussed.
