TMS-EEG for Probing Distinct Modes of Neural Dynamics in the Human Brain

Abstract

We have previously characterized the steady state tuning of auditory cortical cells with a linear model called the spectro-temporal receptive field. It describes the steady-state tuning of cells with respect to the spectro-temporal envelope of a stable sound. On the other hand, speech and other natural sounds have spectro-temporal features that change dramatically over milliseconds. We explore the time evolution of spectro-temporal tuning in primary auditory cortex following a transient in spectro-temporal content and study how cortical cells stabilize to their asymptotic tuning following presentation of a new sound of given spectro-temporal content.
