summaryThe brain is a highly dynamical system, whose neural activity is constantly changing. Yet, in order for it to serve in orchestrating behavior it must maintain a stable realtime representation of the environment. Here we propose a theoretical framework explaining how the different time varying representations offered by individual neurons are woven together to form a coherent working memory of the outside world. From this principle of representational stability we construct a family of networks. Unexpectedly, the structure and dynamics of these networks agrees with many observed properties of cortical networks. Thus, our networks can serve as a biologically-plausible model that captures the essence of activity in cortical circuits with stable representations.
