语言区域的较高大脑体积,如上旋和布罗卡区域,与学生中幻觉倾向的增加有关. 这一发现与显示体积减少的临床研究形成鲜明对比.
科学领域:
- 神经科学是一个神经科学.
- 认知心理学 认知心理学
背景情况:
- 幻觉与大脑结构的变化有关,特别是在语言皮层区域.
- 现有的关于大脑体积和幻觉倾向的模型缺乏实质性的经验支持.
研究的目的:
- 研究特定语言相关皮质区域的幻觉倾向与大脑体积之间的关系.
- 为了检查听觉和视觉幻觉的倾向与上旋和布罗卡的面积体积的关系.
主要方法:
- 在68名大学生中使用劳内-斯莱德幻觉量表 (LSHS) 评估幻觉倾向.
- 使用结构性MRI扫描测量上旋和布罗卡区域的大脑体积.
主要成果:
- 发现LSHS得分和脑体积在上圈和布罗卡区域之间存在显著的正相关性.
- 与较低幻觉倾向的个体相比,具有较高幻觉倾向的个体在这些语言区域中显示出更大的大脑体积.
结论:
- 在语言区域的大脑体积增加可能与非临床人群中幻觉易感增加有关.
- 这一发现挑战了现有的模型,并表明大脑结构和幻觉体验之间存在复杂的关系.
