615-人类小脑多域功能分区图谱

from 聊聊Sci

这项研究利用多领域任务电池(MDTB)对人类小脑的功能结构进行了全面测绘,挑战了传统的解剖学划分方法。通过对受试者进行数十种涉及运动、认知和社会情感任务的磁共振扫描,研究者发现小脑并非仅负责运动控制,而是存在离散的功能分区。实验结果证明,传统的叶状结构边界并不能准确反映功能差异,而新提出的功能分区模型在预测未知任务的表现上优于现有的静息态模型。研究进一步利用认知图谱对这些区域进行了定义,揭示了小脑在注意力、语言和心理推理等高级功能中的关键作用。此外,尽管群体层面存在共性,但个体化分区在捕捉空间细节方面表现出更高的精确度。该研究为未来神经科学探索小脑在健康与疾病中的作用提供了重要的功能图谱工具。References: King M, Hernandez-Castillo C R, Poldrack R A, et al.
