The overall aim of my PhD thesis was to investigate the issue of deriving abstract representations suitable for reasoning and planning from a biomimetic perspective. According to experimental evidence, spatial navigation planning is likely to rely on a distributed neural system in which (i) the hippocampus conveys redundant (and robust) spatial representations to higher cortical areas, (ii) neocortical structures, such as the prefrontal cortex, mediate the elaboration of more abstract and compact representations of the spatial context (e.g., accounting for motivation-dependent memories and action cost/risk constraints) suitable for action planning. Based upon this working hypothesis, we have developed a preliminary navigation planning system. The model is inspired by the columnar organisation of the mammalian cortex, and it provides a neuromimetic architecture capable of learning topological spatial representations and planning goal-directed actions. The planning system has been validated on a classical spatial behavioural task, namely the Tolman & Honzik’s detour protocol (Tolman and Honzik, 1930) whose aim is to show that rodents can use flexible goal-directed trajectories in the presence of blocked pathways. In addition, we used statistical and information theoretic measures to study the neural coding properties of the learnt space representations. The model is now being extended to encode a higher variety of responses of model units (such as prospective-like activity and goal-dependent discharges) and multiscale spatio-temporal correlates.
