使用功能性磁共振成像测量小脑激活，同时7名正常受试者敲击手指，通过音调序列（有或没有音调省略）进行起搏。小脑前叶（拉塞尔的H IV-V）同侧的运动被激活到一个类似的程度，无论是否存在的音调省略。相反，双侧后叶外侧部（HVIIa）的高激活的音调序列与随机遗漏，无论是没有遗漏或定期遗漏。结果表明，HIV-V参与运动执行，而HVIIa的外侧部分参与对不可预测的感觉刺激的在线运动调节。
CEREBELLAR activation was measured using functional magnetic resonance imaging, while seven normal subjects tapped their fingers paced by tone sequences with or without tone omission. The cerebellar anterior lobe (Larsell's H IV-V) ipsilateral to the movement was activated to a similar degree irrespective of the presence or absence of the tone omission. In contrast, the lateral part of the bilateral posterior lobe (H VIIa) was significantly highly activated for the tone sequence with random omission, compared with either that without omission or that with regular omission. The result suggests that the H IV-V is involved in motor execution, while the lateral part of H VIIa is involved in online motor adjustment to unpredictable sensory stimuli.
