HUMAN BRAIN MAPPING:你的痛点有多高，岛叶皮质来决定

岛叶VBM痛阈聚类分数RS-FC
关注

后部IC不仅对于一般的疼痛感知，而且对于确定个体疼痛阈值也是如此。

疼痛被定义为与实际或潜在的组织损伤相关或类似于相关的不愉快的感觉和情感体验，其中疼痛阈值标志着对刺激的感知强度增加曲线上的点，在该点开始感觉到疼痛。痛阈在不同个体之间有很大差异，它们在不同时间内经历了个体间的波动。许多行为/心理特征、遗传因素和神经生物学因素已被确定影响疼痛感知的各个方面，例如痛阈、疼痛耐受和疼痛调节。然而，解释这些差异的神经生物学基础仍有待充分阐明。 在HUMAN BRAIN MAPPING杂志最近刊发的研究文章中，Tobias Schmidt-Wilcke等使用基于体素的形态计量学(VBM)和图论，特别是基于静息态功能连接的局部聚类系数(CC)，来识别大脑区域，其中区域灰质体积和网络特性预测个体痛阈。 在研究疼痛敏感性的神经相关性时，没有研究将脑形态与脑功能联系起来，特别是RS-FC和网络参数。在此背景下，该研究还进行了VBM分析，寻找区域灰质(GM)体积与疼痛敏感性相关的大脑区域。探讨了在某些脑区，网络参数（例如局部CC）和形态参数（即区域GM体积）是否会一致，表明这两种测量方法虽然来自不同的脑成像方法，但不仅与人类感知有关，而且相互关联，表明大脑功能和结构之间存

Translational Psychiatry：岛叶形态学改变与精神障碍临床表型相关

该研究发现较小的脑岛体积在精神病中遵循前后梯度，并为精神病谱障碍提供广泛的风险。脑皮质褶皱减少是精神分裂症特有的，可能反映出产前发育的改变导致认知障碍。

岛叶岛盖局灶性多小脑回所致药物难治性癫痫手术治疗一例

男，29岁。18岁起病，癫痫病程11年。惯常发作有两种形式：①突发右侧肢体不自主抖动，持续数秒至1min左右停止，发作前有右上肢无法描述之不适感，发作时意识清楚，但无法言语，此种发作频率从每日3～5次至每日1次不等，且均于清醒时出现；②突发右侧肢体不自主抖动、头眼右偏，继而意识丧失、四肢强直抽搐，此种发作均于夜间睡眠时出现，发作前无明显先兆，发作结束后意识状态恢复较慢，且初期存在语言功能障碍，此种

PLoS One：涉及岛叶皮质的缺血性卒中，可能是心源性栓塞的危险因素

目的：评估心源性脑栓塞是否与岛叶部位缺血性脑卒中相关。方法：识别症状开始7天内的住院的缺血性卒中患者。基于弥散加权成像，研究包括大脑中动脉（MCA）中缺血性病变。根据梗死是否涉及岛叶，将患者分为两组中一组。主要预后为根据是否涉及岛叶，比较心源性脑栓塞的频率。共有MCAO供血区发生缺血性卒中的患者，112名（8.5%）涉及到岛叶。与未涉及岛叶（30.4%）的患者相比，涉及岛叶卒中（52.7%）的患者

J Neurosurg Anesthesiol：岛叶切除对自主神经活动的影响

岛叶(Insula)为大脑皮质的一部分,是向内凹陷的皮层区域，被包埋在外侧裂之内，无法直接从完整的脑的外部观察到；其与额叶，颞叶和顶叶的皮层相连通。此外，岛叶亦是中枢自主网络的基础结构，在自主神经对环境应激因素的反应中发挥着重要的作用。此前，研究人员主要就脑血管事件，对岛叶在人自主神经调节中的作用进行了探讨，但是由于缺乏脑血管事件前后时间相关进程的对照，使得对于这些发现的解释变得更加复杂。然而，通

立体定向活检诊断双侧岛叶恶性囊性病变1例

患者：女，35岁，因左侧肢体及左侧颜面部间断性麻木6个月伴头痛，于2005年10月到我院就诊。患者入院前1个月在其他医院行头部MRI检查后发现颅内占位病变。患者发病后，无发热，无体重减轻，无抽搐。入院后查体：意识清，双瞳等大同圆，瞳孔直径2.0mm、对光反射灵敏，言语应答准确，左侧上、下肢肌力Ⅳ级，右侧上、下肢肌力Ⅴ级，无病理反射。
