Abstract

Hebbian cell assemblies have been proposed as a model for cortical processing able to bridge between physiology and psychology. Assembly-based theories focused mainly on representations and memory in form of auto-associative attractor states for entities and hetero-associative synfire chains (SFCs) for temporal memories. Here we present a straight and natural extension that also covers the organisation of potentially complex behaviour. We show simulations of a multi-area assembly network comprising simplified visual and motor systems linked by a frontal rule network. The latter binds specific motor responses to differently ordered sequences of input stimuli by means of generic context-dependent associative transitions between assemblies.
