摘要

因颞叶中叶癫痫(MTLE)而切除前颞叶(ATL)的患者在识别熟悉的面孔和明确记忆新学到的面孔方面存在困难,但他们识别陌生面孔的能力在很大程度上仍是未知数。此外,他们在熟悉面孔身份识别和学习方面的困难在多大程度上确实是由于 ATL 切除所致,这一点仍然不得而知。在此,我们报告了一项对 24 名 MTLE 患者和匹配的健康对照组进行的研究,在单侧(9 名左侧,15 名右侧)ATL 切除术前和术后约 6 个月,他们接受了广泛的 7 项人脸和视觉对象识别任务(包括 3 项评估陌生人脸个体化的任务)的测试。我们发现,无论是在群体还是个体层面,ATL 切除术对患者手术前保持的陌生面孔识别能力几乎没有影响。更令人惊讶的是,ATL切除术对患者识别和命名著名面孔以及学习新面孔的能力也几乎没有影响。相当一部分右侧 MTLE 患者(33%)甚至改善了他们在多项任务中的反应时间,这可能表明右侧 ATL 切除术后视觉空间处理功能得到了释放。总之,这项研究表明,MTLE 患者的人脸识别能力主要不受 ATL 切除术的影响,这可能是因为人脸识别的关键区域未受影响,也可能是因为某些任务的表现在术前已低于正常水平。总之,在解释因 MTLE 而进行 ATL 切除术的患者的大脑病变对人脸识别能力的因果影响时,这些研究结果值得警惕。这些研究结果还说明了预测癫痫手术后认知结果的复杂性,因为这受到许多不同因素交织在一起的影响。

Stability of face recognition abilities after left or right anterior temporal lobectomy

Patients with anterior temporal lobe (ATL) resection due to mesial temporal lobe epilepsy (MTLE) have difficulties at identifying familiar faces and explicitly remembering newly learned faces but their ability to individuate unfamiliar faces remains largely unknown. Moreover, the extent to which their difficulties with familiar face identity recognition and learning is truly due to the ATL resection remains unknown. Here, we report a study of 24 MTLE patients and matched healthy controls tested with an extensive set of seven face and visual object recognition tasks (including three tasks evaluating unfamiliar face individuation) before and about 6 months after unilateral (nine left, 15 right) ATL resection. We found that ATL resection has little or no effect on the patients' preserved pre-surgical ability to perform unfamiliar face individuation, both at the group and individual levels. More surprisingly, ATL resection also has little effect on the patients' performance at recognizing and naming famous faces as well as at learning new faces. A substantial proportion of right MTLE patients (33%) even improved their response times on several tasks, which may indicate a functional release of visuo-spatial processing after resection in the right ATL. Altogether this study shows that face recognition abilities are mainly unaffected by ATL resection in MTLE, either because the critical regions for face recognition are spared or because performance at some tasks is already lower than normal preoperatively. Overall, these findings urge caution when interpreting the causal effect of brain lesions on face recognition ability in patients with ATL resection due to MTLE. They also illustrate the complexity of predicting cognitive outcomes after epilepsy surgery because of the influence of many different intertwined factors.

期刊介绍: The Journal of Neuropsychology publishes original contributions to scientific knowledge in neuropsychology including: • clinical and research studies with neurological, psychiatric and psychological patient populations in all age groups • behavioural or pharmacological treatment regimes • cognitive experimentation and neuroimaging • multidisciplinary approach embracing areas such as developmental psychology, neurology, psychiatry, physiology, endocrinology, pharmacology and imaging science The following types of paper are invited: • papers reporting original empirical investigations • theoretical papers; provided that these are sufficiently related to empirical data • review articles, which need not be exhaustive, but which should give an interpretation of the state of research in a given field and, where appropriate, identify its clinical implications • brief reports and comments • case reports • fast-track papers (included in the issue following acceptation) reaction and rebuttals (short reactions to publications in JNP followed by an invited rebuttal of the original authors) • special issues.
