Brain-State-Dependent Modulation of Neuronal Firing and Membrane Potential Dynamics in the Somatosensory Thalamus during Natural Sleep

Abstract

Urbain et al. measure membrane potential and action potential firing in somatosensory thalamus linked with cortical dynamics in naturally sleeping head-restrained mice. VPM and Pom neurons display specific phase-locking to cortical spindle and slow waves. VPM cells further display subthreshold spindle oscillations that only partially overlap cortical spindles.
