感谢楼主分享~新阅读大脑记忆求确认么么~
Working memoryV1
第一篇说的是"working memory"。P1先解释“WM”是什么,就是短暂记忆,人们平时用于记电话,读一个句子理解前后文时的短暂记忆。然后说某科学家发现人们用“WM”时脑里的某一部分活跃什么什么的,这个理论推翻了之前的一个理论。
P2作一个什么办法来pinpoint大脑在用“WM”时的具体活动位置。
V2
一篇是讲大脑传递信息的,叫working memory。有个人认为这个功能是在大脑的前额后面的一个地方负责的。并且不同的subregion负责不同的信息,如空间信息,形象信息等。这与传统的executive system理论不同。
第二段又说有一个新实验,加强了那个人的理论。问题中问如果试验出什么结果,就会greatly undermine那个人的理论。
V3
关于大脑储存信息的机制.
第一段: GP 发现大脑的不同SUBREGION 负责处理不同的信息. 这与STANDARD 观点不同. 传统观点人为大脑的EXECUTIVE INFORMAITON CENTER 管理信息处理.
第二段: 有个新实验,证实GP的观点正确.
V4
Working Memory 新老观点
P1: 讲述人大脑的Working Memory的短暂记忆,是由大脑的P部位来控制,认为不同的部位控制不同的功能之类。这与Standard 的方法不一样,有什么Executive function之类(旧观点)。
P2: 后来一位研究证实了新观点的正确性,指出了旧观点的矛盾指出,Executive function之类的。说明了同的部位控制不同的功能之类。
V5
关于working memory 的大意记不太清了:
1。working memory 是和executive memory 相对的;有人发现working memory 储存在大脑的cortex中,而原来的理论说working memory分散在cortex之外
2。另一个人发现 when recognize faces, the middle part of cortex is most active. 。。。
不好意思记不太清不误导大家了问题有一道较难就问第二个人的发现可以用作什么的证据?
我选的是:the middle part of cortex is most important to working memory 类似的,不知道是不是对
这篇整体感觉挺难的大家小心
Google 上找到一篇,不是原文,但很有帮助。
Working memory is the process of maintaining a limited amount of information in an active representation for a brief period of time so that it is available for use. Therefore, by de¢nition, working memory includes those processes that enable us to hold in our `mind's eye' the contents of our conscious awareness, even in the absence of sensory input. Thus, the study of working memory
provides a framework for investigating the neural system underlying our awareness of stimuli, memories and knowledge that are no longer tied to perceptual events. Although the neural system responsible for working memory is known to include a large number of brain regions, there is abundant evidence from neurophysiological and lesion studies in monkeys that prefrontal cortex is a critical component (Fuster 1990; Goldman Rakic 1990). Recent brain-imaging studies, using positron emission tomography (PET) and functional magnetic resonance imaging (fMRI), have also implicated the human prefrontal cortex in working memory. However, there remain questions and somedispute about the functional organization of the human prefrontal cortex and its exact role in working memory.
Here we summarize the evidence for working memory-related activity within human prefrontal cortex. We then present evidence for domain speci¢city within frontal cortex for object working memory as opposed to spatial visual working memory. We also review evidence suggesting an additional dimension of domain speci¢city for object working memory based on whether the type of representation is analytic or image-like. In addition, we discuss evidence suggesting a third dimension for the specialization of working memory function in prefrontal cortex that distinguishes regions important for the maintenance of the contents held in working memory from regions important for the manipulation of those contents.
Finally, we consider the relationship of prefrontal areas important for working memory, both to posterior visual processing areas and to prefrontal areas associated with long-term memory.
考题
1.有1题是问这tech的新发现证明了什么理论是真的
我选新观点是对的
2.主旨题
3.问题中问如果试验出什么结果,就会greatly undermine那个人的理论
4.就问第二个人的发现可以用作什么的证据?
我选的是:the middle part of cortex is most important to working memory 类似的,不知道是不是对
5.mri的作用是什么。
6.问题有一道较难就问第二个人的发现可以用作什么的证据?
我选的是:the middle part of cortex is most important to working memory 类似的,不知道是不是对
