Abstract

Abstract Downing and Peelen argue that the extrastriate body area (EBA) creates an unelaborated visual repre- sentation of the human body, but is not implicated in any higher-order computational process. We believe that this reflects an outdated view of brain function, in which neural regions are informationally encapsulated modules with fixed computational properties. In contrast, there is mounting evidence that functional properties may not be fixed but may be dependent on the context in which the region is recruited. We will illustrate this by taking a closer look at a visual area of which the properties are potentially even simpler: the primary visual cortex.

摘要

摘要

唐宁和皮尔林认为,梭状回身体区域(EBA)对人体进行了不加区分的视觉呈现,但不涉及任何更高阶的计算过程。我们认为,这反映了一种过时的大脑功能观点,即神经区域是具有固定计算属性的信息封装模块。相比之下,越来越多的证据表明,功能特性可能不是固定的,而是可能取决于该区域被招募的上下文。我们将通过更仔细地研究一个潜在特性甚至更简单的视觉区域来说明这一点:初级视觉皮层。
