Contingent negative variation (CNV) and Bereitschaftspotential (BP) were from the scalp in a patient with a discrete infarct in the mesial tegmentum of the midbrain involving the decussation of the superior cerebellar peduncle. Bereitschaftspotential in association with hand movements was completely absent while CNV was normally present at the frontocentral midline. This indicates that CNV is, as opposed to BP, generated without cerebro-cerebellar interactivation, suggesting different generating mechanisms.
在一名中脑内侧被盖离散梗死累及上小脑脚交叉的患者中，头皮记录到了关联性负变（CNV）和运动准备电位（BP）。与手部运动相关的运动准备电位完全缺失，而关联性负变在额中央中线处正常出现。这表明，与运动准备电位不同，关联性负变的产生不涉及大脑与小脑之间的相互激活，提示两者的产生机制不同。
