Abstract:
Objective To observe the effects of repeated subconvulsive electrical stimulations to hippocampus on rat's emotional behavior and spatial learning and memory. Mehtods The hippocampus of Wistar rats were repeatedly stimulated by constant pulsating current with intratrain frequencies of 16 Hz, pulsating duration of 1 ms, train duration of 10 s and interstimulus interval of 7 min for 5 days. Results The experimental rats displayed the long-term significant abnormalities of emotional behaviors, such as substantial changes of behavioral habits, hyperarousal, hypersensitive frightened reactions, anxiety-like behaviors, and transitory spatial learning and memory disorder. Conclusion The stable and practical animal model satisfied most characteristics of posttraumatic stress disorder (PTSD).
