Cell Assemblies in the Cerebral Cortex

To say that an animal responds to sensory stimuli may not be the most natural and efficient way to describe behaviour. Rather, it appears that animals most of the time react to situations, to opponents or things which they actively isolate from their environment, Situations, things, partners or opponents are, in a way, the terms of behaviour. It is legitimate, therefore, to ask what phenomena correspond to them in the internal activity of the brain, or, in other words: how are the meaningful chunks of experience “represented” in the brain?
