[Abstract.] Music is a highly complex and versatile stimulus for the brain that engages many temporal,
frontal, parietal, cerebellar, and subcortical areas involved in auditory, cognitive, emotional,
and motor processing. Regular musical activities have been shown to effectively enhance
the structure and function of many brain areas, making music a potential tool also in neuro-
logical rehabilitation. In our previous randomized controlled study, we found that listening to
music on a daily basis can improve cognitive recovery and improve mood after an acute mid-
dle cerebral artery stroke. Extending this study, a voxel-based morphometry (VBM) analysis
utilizing cost function masking was performed on the acute and 6-month post-stroke stage
structural magnetic resonance imaging data of the patients (
n
D
49) who either listened to
their favorite music [music group (MG),
n
D
16] or verbal material [audio book group (ABG),
n
D
18] or did not receive any listening material [control group (CG),
n
D
15] during the 6-
month recovery period. Although all groups showed significant gray matter volume (GMV)
increases from the acute to the 6-month stage, there was a specific network of frontal
areas [left and right superior frontal gyrus (SFG), right medial SFG] and limbic areas [left ven-
tral/subgenual anterior cingulate cortex (SACC) and right ventral striatum (VS)] in patients
with left hemisphere damage in which the GMV increases were larger in the MG than in the
ABG and in the CG. Moreover, the GM reorganization in the frontal areas correlated with
enhanced recovery of verbal memory, focused attention, and language skills, whereas the
GM reorganization in the SACC correlated with reduced negative mood. This study adds on
previous results, showing that music listening after stroke not only enhances behavioral
recovery, but also induces fine-grained neuroanatomical changes in the recovering brain.
