Figure 2. Anesthesia promotes autophagic activity, as shown in subicular pyramidal neurons of 21-day-old rats.

A) In experimental pyramidal neurons, numerous lysosomes (double asterisks) and autophagic vacuoles (arrowheads) were dispersed throughout the cytoplasm. B) Autophagosomes, double-layered membrane structures, were frequently noted in experimental neurons where parts of cannibalized mitochondria could be detected (single asterisk).
