Seminar by Jessica Grahn on rhythm processing in the brain

On Thursday April 30th at 3pm in room 52.321 Jessica Grahn from the MRC Cognition and Brain Sciences Unit of Cambridge, UK, will give a seminar on "Rhythm processing in the brain: a focus on motor areas".

Abstract: Perception of auditory rhythms activates brain areas typically associated with movement (premotor cortex (PMC), supplementary motor area (SMA), cerebellum, and basal ganglia), in addition to auditory areas. This talk will describe a series of functional neuroimaging studies that examine how different types of rhythmic patterns are processed in the brain. In particular, regular versus irregular rhythms, different accent types (volume accents vs duration accents vs no accents), and changes in tempi (speeding up or slowing down) are examined. Data will be presented that describes interactions between auditory and motor brain areas, and I will describe behavioural work with Parkinson's disease patients that indicates subtle impairments for certain types of regular beat-based rhythms.
