The event-related potential (ERP) is considered as one of the most effective methods to study and analyze objectively human mental activity based on nerve electrophysiology. At present, ERP is not only used in the study of lie detection, but also in the clinical medicine for the cognitive assess-ment on patients with cerebrovascular disease, dementia or traumatic brain injury and auxiliary diagnosis of mental illness. with the further development of ERP detection technology, it would have a wider ap-plication prospect in the field of forensic medicine.%事件相关电位（event-related potential，ERP）是从神经电生理层面客观分析和研究人体心理活动的最有效方法之一。目前主要用于测谎等研究，在临床上，还用于脑血管疾病、痴呆、创伤性脑损伤患者认知能力评估以及精神心理疾病的辅助诊断。随着ERP检测技术的进一步发展，在法医学领域必将具有更为广泛的应用前景。
