一些大型的元分析研究未能支持视觉或“非语言”记忆缺陷与右侧内侧颞叶变化之间的一致关系。然而,Brown Location测试(BLT)是最近发展起来的一种点位置学习和记忆测试,它使用非对称阵列,并提供对其他视觉记忆测量中固有的许多混杂变量(例如,语言影响和绘画要求)的控制。在目前的研究中,我们评估了BLT在接受左侧或右侧前内侧颞叶切除术患者中的临床应用。我们还提供了298名健康成年人的成人常模数据,以提供标准化分数。结果显示,与左侧肺叶切除组和健康成人正常样本相比,右侧BLT的表现明显差。目前的研究结果支持右前内侧颞叶在点位置学习和记忆中的作用。
Several large and meta-analytic studies have failed to support a consistent relationship between visual or “nonverbal” memory deficits and right mesial temporal lobe changes. However, the Brown Location Test (BLT) is a recently developed dot location learning and memory test that uses a nonsymmetrical array and provides control over many of the confounding variables (e.g., verbal influence and drawing requirements) inherent in other measures of visual memory. In the present investigation, we evaluated the clinical utility of the BLT in patients who had undergone left or right anterior mesial temporal lobectomies. We also provide adult normative data of 298 healthy adults in order to provide standardized scores. Results revealed significantly worse performance on the BLT in the right as compared to left lobectomy group and the healthy adult normative sample. The present findings support a role for the right anterior-mesial temporal lobe in dot location learning and memory.
