Using Temporal Binding for Robust Connectionist Recruitment Learning over Delayed Lines ∗

However, synchronized spikes must travel over cortical circuits that have varying-length pathways, leading to mismatched arrival times. This raises the question of how initial stimulus-dependent synchrony might be preserved at a destination binding site. Earlier, we proposed constraints on tolerance and segregation parameters for a phase-coding approach, within cortical circuits, to address this question [ 22]. The purpose of the present paper is twofold. First, we conduct simulation experiments to test the proposed constraints. Second, we explore the practicality of temporal binding to drive a process of long∗A similar version of this report has been submitted to the Neurocomputing Journal Special Issue on Spiking Neural Systems. term memory formation based on a recruitment learning
