Activation on a motor task was used to seed a resting
state connectivity analysis in the left primary motor
cortex (M1) in 48 participants in the prodromal stages
of Huntingtons disease (preHD) and 16 gene-negative
participants. Bilateral anterior cerebellar lobes and
bilateral middle temporal gyri showed a relationship
between strength of connectivity to left M1 and
time-to-onset in preHD. These findings suggest that
connectivity strength is impacted by disease process
prior to onset of symptoms in HD.
