Abstract

A modular view of brain function dominates the teaching of medical students and clinical psychologists and is implicit in day-to-day clinical practice. This view glosses over a long-standing debate. The extent of one-to-one mappings between region and function remains a controversial topic. For the cortex, localisation of function versus ‘cerebral equipotentiality’ was debated less than 150 years ago, and traces of this debate remain active in systems neuroscience today. The advent of functional brain imaging led to an explosion of evidence on localisation of function studied in vivo, and a gold rush to map an ever-increasing range of ‘functions’. Rapid growth in knowledge was accompanied, to some extent, by a flourishing neuromythology. There are currently few clinical applications of brain mapping techniques, but new areas are emerging. An understanding of the central debate on functional localisation will bring a more nuanced view of problems encountered in clinical practice. No data are available.

大脑功能定位:反思
在医科学生和临床心理学家的教学中,大脑功能的模块化观点占据主导地位,并隐含在日常临床实践中。这种观点掩盖了一个长期存在的争论。区域和功能之间一一对应的程度仍然是一个有争议的话题。就皮层而言,功能定位与 "脑等同性 "的争论不到 150 年前就已开始,这一争论的痕迹至今仍活跃在系统神经科学领域。脑功能成像技术的出现导致了体内功能定位研究证据的爆炸式增长,以及绘制范围越来越广的 "功能 "地图的淘金热。知识的快速增长在一定程度上伴随着神经选学的蓬勃发展。目前,脑图绘制技术在临床上的应用还很少,但新的领域正在出现。了解关于功能定位的核心争论将为临床实践中遇到的问题带来更细致的看法。暂无数据。

期刊介绍: The essential point of Practical Neurology is that it is practical in the sense of being useful for everyone who sees neurological patients and who wants to keep up to date, and safe, in managing them. In other words this is a journal for jobbing neurologists - which most of us are for at least part of our time - who plough through the tension headaches and funny turns week in and week out. Primary research literature potentially relevant to routine clinical practice is far too much for any neurologist to read, let alone understand, critically appraise and assimilate. Therefore, if research is to influence clinical practice appropriately and quickly it has to be digested and provided to neurologists in an informative and convenient way.
