Le CINQ accueille pour cette quatrième conférence hivernale Mme Virginia Penhune, professeur du département de psychologie de l'Université Concordia. Mme Penhune est aussi directrice du laboratoire pour Motor Learning and Neural Plasticity.
When we produce speech or music we have two goals: the sounds we want to make and the movements required to make them. As we learn to play or speak, sounds and actions become linked through internal models, and production becomes more fluid. Sound-action links are also important because they allow us to make predictions about upcoming sensory information, or movements to be made. The brain regions important for linking sound and action are part of what is known as the dorsal auditory stream, which includes the posterior superior temporal gyrus (STG), parietal and premotor cortex (PMC), prefrontal regions, and subcortical structures such as the basal ganglia and cerebellum. This talk will examine the role of dorsal stream regions in auditory motor integration in the context of studies of rhythm perception and production, as well as musical training and expertise.
