Abstract (summary): Previous studies using continuous theta burst stimulation (cTBS) applied to Crus I of the lateral cerebellum have demonstrated an inhibition of the contralateral motor cortex and connections in the cerebello-thalamo-cortical (CTC) pathway. The aim of this thesis was to determine the effects of lateral cerebellar cTBS on cognitive and motor cerebello-cerebral networks using resting state functional magnetic resonance imaging (rsfMRI). Functional connectivity between four cerebello-cerebral seed pairs constituting the cognitive network [Crus I – Brodmann area (BA) 7, Crus I – BA8, Crus I – BA9, Crus I – BA39] and one cerebello-cerebral seed pair constituting the motor network (Lobule V hand area – BA4 hand area) were measured before and after cTBS in 12 healthy subjects. As hypothesized, lateral cerebellar cTBS induced a significant decrease in functional connectivity within the cognitive network, while motor functional connectivity remained unaltered. These results provide further insight into the effects of cerebellar cTBS at the network level.
