Repetitive speech elicits widespread deactivation in the human cortex: the “<scp>M</scp>antra” effect?

Abstract

Our results are compatible with a global gating model that can exert a widespread induction of negative BOLD in the absence of a corresponding positive activation. The triggering of a global inhibition by the minimally demanding repetitive speech may account for the long-established psychological calming effect associated with commonly practiced Mantra-related meditative practices.
