Abstract

Recognition and generation of temporal sequences are fundamental capacities of human and animal cognition. Nevertheless, our understanding of the computational basis of these capacities remains limited. Many models have been proposed, but what do they tell us about the neural mechanisms? Does a unifying principle exist, or is sequence processing implemented by diverse neural algorithms? The workshop brings together theoretical and model-based approaches to explain sequence processing in the brain. It aims to foster discussion about the computational principles that support both the sequential propagation of neuronal activity (sequence generation) and the integration of temporal patterns (sequence recognition) in biological networks.
