Contingent negative variation (CNV) is a negative cerebral potential which is related to attention and arousal. CNV occurs during an experimental situation in which stimuli and responses are serially organized. Between attacks migraine patients have on average higher negative amplitudes compared to healthy controls or patients with tension-type headache. Successful treatment with beta-blocking agents decreases CNV amplitudes. In spite of encouraging findings in neurological disorders, CNV is not widely used. In this review some possible reasons for this are pointed out.
关联性负变（CNV）是一种与注意力和觉醒相关的负性脑电位。CNV出现在刺激和反应按顺序组织的实验情境中。在发作间期，偏头痛患者的负性波幅平均高于健康对照组或紧张型头痛患者。使用β受体阻滞剂成功治疗可降低CNV波幅。尽管在神经系统疾病中取得了令人鼓舞的发现，但CNV并未得到广泛应用。在这篇综述中指出了一些可能的原因。
