摘要

The recent success of deep neural networks in modeling complex perceptual and cognitive functions has led to comparisons between these artificial networks and the biological neural networks that make up animal and human brains. In particular, the layered architecture of deep neural networks, with each layer specialized for extracting specific types of features from the input, has invited analogies to the modular organization of brain regions specialized for certain cognitive processes. However, modularity theories of brain function overemphasize specialized areas at the expense of distributed processing and interconnectivity.
