Abstract

Goal-driven selective attention (GDSA) is a phenomenon that allows the brain to identify, separate, and process relevant and irrelevant information for use in various brain functions such as sensory processing, perception, and memory. Many of the functions relying on GDSA involve networks connecting the thalamus with the cerebral cortex in different topological configurations. This work investigates the thalamocortical network principles underlying GDSA using a control-theoretic approach. Modeling brain dynamics with a linear-threshold firing rate model, our approach allows for a detailed treatment of the hierarchical nature of the brain using tools from singular perturbation theory and switched systems. We illustrate, in particular, how the two components of GDSA, namely, selective recruitment and inhibition, can be achieved in multiple network topologies and discuss the similarities and differences thereof.
