In the last decade several discoveries in relation to neurons and how they are interconnected, forming networks, made possible the study of the dynamics of the storage and processing of information by the brain. In particular, the physicist JJHopfield proposed a formal, minimalist model for these neural networks, reducing the problem to a particular case of a well-defined physical system - spin glass. Although the problem is well defined, its solution is far from trivial. In this text we introduce the problem, describe the Hopfield model with its results and limitations and present our contribution to the description of the information storage in networks of neuron
