Auditory vocal hallucinations are sometimes observed in temporal-lobe epilepsy, but are a frequent sign of psychosis and may rarely be mistaken for the latter. Here we report two patients who suffered from auditory vocal hallucinations, described as unintelligible human voices perceived at their left side during epileptic seizures. MEG revealed interictal epileptic discharges within the anterior partition of the right superior temporal gyrus; signal-to-noise ratio of these discharges was overall poor in EEG. The findings suggest that auditory vocal hallucinations without verbal content can evolve in the right hemisphere and are probably independent of language lateralization. This is in accordance with evidence from functional imaging, whereas most previous reports of seizures with auditory vocal hallucinations were confined to the left hemisphere.
听觉性幻听有时在颞叶癫痫中观察到，但这是精神病的常见症状，且可能很少被误诊为后者。在这里，我们报告了两名患者，他们在癫痫发作期间出现听觉性幻听，被描述为在左侧听到无法理解的人声。MEG 显示发作间期痫性放电位于右侧上颞叶前部分隔区；这些放电在 EEG 中的信噪比总体较差。这些发现表明，无言语内容的听觉性幻听可能在右半球演变，且可能与语言偏侧化无关。这与功能成像的证据一致，而之前大多数关于伴有听觉性幻听的癫痫发作的报告都局限于左半球。
