4.1. Sensory–motor network
This network is central to the execution of voluntary movements ( Biswal et al., 1995 ) and abnormalities in the functional connectiv- ity of the sensory–motor network have been reported in Parkinson’s patients. In addition the topography features of this network may be dopamine dependent ( Esposito et al., 2013 ). Therefore, given the presence of parkinsonism in DLB, it is not unsurprising that we found that FC of this network was affected.
