Our aim was to determine whether everyday music and speech listening could enhance auditory brain plasticity after stroke. In the acute recovery phase, 60 middle cerebral artery (MCA) stroke patients were randomly assigned to a music listening group, an audio book listening group, or a control group. Preattentive sound discrimination, as indexed by the magnetic mismatch negativity (MMNm) response, was measured 1 week (baseline), 3 months, and 6 months after the stroke with whole-head magnetoencephalography (MEG) recordings. Results showed that both music and audio book listening enhanced the MMNm to a change in sound duration, but only music listening enhanced the MMNm to a change in sound frequency (pitch), especially in patients who had damage to the right temporal lobe. These findings demonstrate that merely listening to music and speech can induce long-term auditory plastic changes that follow the spectral and temporal features of the listening material. Clinically, the results encourage the use of music and audio book listening in neurological rehabilitation. Conference: Tuning the Brain for Music, Helsinki, Finland, 5 Feb - 6 Feb, 2009.
