Vi presentiamo una procedura sperimentale per la misurazione della pressione parziale di ossigeno (pO2) in vasi cerebrali sulla base di ossigeno-dipendente tempra di fosforescenza. Preparazione degli animali e delle procedure di imaging sono stati delineati per entrambi ampio campo visivo CCD-based imaging di pO2 nel ratto e nel 2-fotoni immagini eccitazione base di pO2 nei topi.
