Processing incoming sensory information and transforming this input into appropriate motor responses is a critical and ongoing aspect of our moment-to-moment interaction with the environment. While the neural mechanisms in the posterior parietal cortex (PPC) that support the transformation of sensory inputs into simple eye or limb movements has received a great deal of empirical attention - in part because these processes are easy to study in non-human primates - little work has been done on sensory-motor transformations in the domain of speech. Here, we used fMRI and multivariate analysis techniques to demonstrate that a region of the Planum Temporale (Spt) shows distinct spatial activation patterns during sensory and motor aspects of a speech task. This result suggests that just as the PPC supports sensorimotor integration for eye and limb movements, the Spt forms a sensory-motor integration circuit for the vocal tract.
