| summary | The neural mechanisms of inner speech remain unclear despite its implications in cognition and auditory verbal hallucinations. Previous research has proposed a corollary discharge model where inner speech is a sensory prediction of intended articulation, linking it to increased activity in speech production-related regions such as the left inferior frontal gyrus. However, this model may not fully capture the diverse phenomenology of inner speech and recent research suggests alternative, perception-related mechanisms of inner speech generation. Here, we introduce a framework in which inner speech is flexibly generated by two complementary mechanisms, depending on its phenomenological qualities: a corollary discharge mechanism relying on speech production regions and a perceptual simulation mechanism involving speech perceptual regions. A review of recent studies and an activation likelihood estimation meta-analysis support the idea that varieties of inner speech differentially recruit these neural mechanisms. |
