One aspect of the results obtained using the Sternberg Item Recognition Paradigm to investigate working memory.
功能性磁振造影让我们得以看到当脑在进行有意识或无意识思考时,脑部于何处与何时产生活动的改变。上面这张图显示在以Sternberg项目(item在实验中可以是物体、脸孔、文字、图形、声音…等)辨认实验来探索工作记忆时,在脑部产生反应的部分结果,让我们可以了解人们如何把一个想法记在“心里”一小段时间。当受试者把心里面记住的资讯跟实验者问的问题进行比对时,在后侧前额叶皮层(DLPFC)和辅助运动区(SMA)产生了脑活动的改变,这种活动的增加,在用来描述受试者脑部活动的假色统计图谱上,是以暖色(黄跟红色)来呈现,并重叠在标准的解剖结构核磁共振影像样版上。(资料来源:由NCRR所资助,以开发校正与标准化核磁共振技术为目的之生医资讯研究网计划。影像来源:D.

Functional magnetic resonance imaging makes visible where and when regions of the brain change activity to support conscious and unconscious thoughts. This figure illustrates one aspect of the results obtained using the Sternberg Item Recognition Paradigm to investigate working memory; how a person keeps a thought "in mind" for a short period of time. Regions of increased activity in the Dorsolateral Prefrontal cortex (DLPFC) and Supplementary Motor Area (SMA) are observed during the act of matching the information held in memory to a question asked by the experimenter. This increased activity is indicated by the hotter colors (yellow and red) of the pseudo-color statistical maps describing the activity of one subject’s brain overlaid on a standardized anatomical template structural magnetic resonance image.

课程描述

这个由多位教师共同教学的跨领域课程,将涵盖用来进行与解释人脑图谱研究有关的核磁共振影像基本原理。课程首先会把运用功能性磁振造影来拓展脑功能的知识时所会面临的挑战提出来,接着深入介绍包括影像构成的物理原理、影像对比形成机制,以及影像信号的生理基础等主题,并讨论脑组织与脑血管的神经解剖学,还有运用复杂的结构分析算法对功能性影像资料进行分割与对位的方法。课程还会介绍功能性磁振造影实验设计,包括区块式设计、事件相关及探索性资料分析方法、建立与运用功能性磁振造影资料的统计模式等。此外,也将涵盖跟人体实验有关的课题,包括:知情同意、机构的常规审查委员会要求,以及在高磁场环境下的安全性等。

This team taught, multidisciplinary course covers the fundamentals of magnetic resonance imaging relevant to the conduct and interpretation of human brain mapping studies. The challenges inherent in advancing our knowledge about brain function using fMRI are presented first to put the work in context. The course then provides in depth coverage of the physics of image formation, mechanisms of image contrast, and the physiological basis for image signals. Parenchymal and cerebrovascular neuroanatomy and application of sophisticated structural analysis algorithms for segmentation and registration of functional data are discussed. Additional topics include fMRI experimental design including block design, event related and exploratory data analysis methods, building and applying statistical models for fMRI data. Human subject's issues including informed consent, institutional review board requirements and safety in the high field environment are presented.
