[Evaluation of brain dysfunction in chronic anoxic encephalopathy with evoked potentials].

Aim: To explore the relationship between evoked potentials (EPs) and chronic anoxic brain damage by chronic intermittent hypoxia (CIH), and provide theory evidence for diagnosis and treatment of anoxic encephalopathy.

Methods: BAEP and SLSEP were recorded in rat model with CIH (hypoxia group) and rat with normoxia (normal group). Morris water maze was used to observe learning and memory ability.
