大脑的状态代表着世界的状态。但至少有一些头脑-大脑的内部表现形式，如热感或红色感觉，与它们所代表的外部现实并不相似：平均动能(温度)或电磁反射(颜色)。历史上的反应是区分客观真实的属性，如形状和运动，以及主观属性，如热和颜色。然而，这种方法会带来麻烦。认知神经生物学面临的一个挑战是，概括地描述大脑模型与世界之间的关系。我们认为大脑形成高维地图，其内部距离关系对应于构成世界范畴结构的相似关系。
States of the brain represent states of the world. But at least some of the mind–brain's internal representations, such as a sensation of heat or a sensation of red, do not resemble the external realities that they represent: mean kinetic energy (temperature) or electromagnetic reflectance (colour). The historical response has been to distinguish between objectively real properties, such as shape and motion, and subjective properties, such as heat and colour. However, this approach leads to trouble. A challenge for cognitive neurobiology is to characterize, in general terms, the relationship between brain models and the world. We propose that brains develop high-dimensional maps, the internal distance relationships of which correspond to the similarity relationships that constitute the categorical structure of the world.
