Pure ictal non-speech vocalisation occurs in frontal and temporal lobe epilepsies. Electrical stimulation of supplementary motor areas is reported to evoke vocalisation in selected patients. Here, we report a patient with focal epilepsy of the left anterior insula who had isolated monotonous vocalisation elicited by electrical stimulation of the left superior frontal gyrus. Quantitative analysis of audio signals was performed and compared with a former patient with left frontal lobe epilepsy who had pure ictal vocalisation. Both patients showed a comparable reduction in frequency variation indicating a monotonous voice. [Published with video sequences on www.epilepticdisorders.com].
单纯发作期非言语发声可出现于额叶和颞叶癫痫。有报道称，刺激辅助运动区可诱发部分患者出现发声。在此，我们报告一例左侧额下回局灶性癫痫患者，其左侧额上回电刺激可引发单纯发作期单调发声。对音频信号进行定量分析，并与一例左侧额叶癫痫纯发作期发声患者进行比较。两名患者的频率变化均有相似减少，提示为单调声。[发表于 www.epilepticdisorders.com，伴有视频序列]。
