Self-controlled latching dynamics in simple models with attractor-ruins — •Diemut Regel and Marc Timme — Network Dynamics, MPI for Dynamics and Self-Organization, 37077 Goettingen, Germany

Standard models of natural computation commonly exhibit attractors as their core concept, with convergence dynamics towards them viewed as the completion of a computational task, e.g. the recognition of an object or the processing of a piece of information [1]. Higher cognitive activities such as free association have been proposed to be representable by latching dynamics [2], a repeated switching between representative system states by dynamical parameter drifting that is intrinsically controlled by the system itself. Yet, how such latching might be achieved and which mechanism may cause latching in dynamical systems is not well understood. Here we propose simple models of latching dynamics and reveal fundamental mechanisms of their self-control options.
