Musical Training Changes the Intra- and Inter-network Functional Connectivity

Previous studies have evidenced that musical training can change the brain functional and structural organizations, but it is still unclear how interactions within and between functional networks are affected by musical training. Using the resting-state fMRI dataset with a relatively large sample, the present study examined the effects of musical training on inter- and intra-network functional connectivity (FC). The results revealed the decreased inter- and intra-network FC extensively which reflect greater movement efficiency and automaticity as well as five pairs of increased inter-network FC that possibly refer to cognitive function in participants with musical training compared to their counterparts without musical training. The current study provided a new perspective that musical training can induce the brain network changes.
