Abstract

Thalamic and cortical neurons are richly and reciprocally interconnected and support recurrent functional loops in the intact brain, but the role of this circuitry is still poorly understood. Here, we present evidence—from cellular and from functional neuroimaging in control and clinical domains—that thalamocortical resonance is not only a prerequisite for normal cognition, but that its perturbation, in a dynamic sense (e.g. a dysrhythmia) can underlie a variety of neurological and psychiatric disorders.
