Temperature affects adult neurogenesis in the lizard brain
Published: 1 June 2001
Abstract
Postnatal and adult neurogenesis have been reported to occur in the brain of lizards. The aim of this study was to know if adult neurogenesis is a temperature-dependent process. We have shown, by using 5'-bromodeoxiuridine immunocytochemistry, that at low temperatures the number of newly generated neurones was significantly decreased (70%-90%) in several telencephalic areas of the lizard Psammodromus algirus. On the other hand, the migration process was also affected by low temperatures. This study provides evidence for a potential temperature-modulation of adult neurogenesis in lizards as it may occur during seasonal changes.
