Anatomopathological studies are reported of 5 brains in which electrical stimulation of the periventricular--periaqueductal gray was applied for the treatment of chronic pain. It was found that the recommended target was reached in 4 cases (only 1 case out of 5 was successful as far as a pain relief is concerned). PtIr electrodes caused little tissue reaction. The chronic stimulation had not provoked lesions observable by light-microscopy.
报告了5例脑部的解剖病理学研究，其中对室周-导水管周围灰质进行电刺激以治疗慢性疼痛。结果发现，4例达到了推荐的靶点（就疼痛缓解而言，5例中只有1例成功）。铂铱电极引起的组织反应很小。慢性刺激未引发光镜下可观察到的病变。
