Topic: Hopfield model

The Potts associative network, a neurally-informed generalization of the Hopfield model, can serve as a simplified representation of global cortical dynamics. Considering memories to be sparsely distributed patterns of local cortical activity, we have studied latching dynamics – the largely random hopping through global attractor states driven by adaptation – as a regime potentially underlying complex cognition such as language production and mind wandering. In a recent study, we have differentiated a Potts associative network into two parts, representing frontal and posterior cortices, to cru
