abstract = {Deep brain stimulation of the subthalamic nucleus is an
established treatment for the motor symptoms of Parkinson's
disease. Given the frequent occurrence of
stimulation-induced affective and cognitive adverse effects,
a better understanding about the role of the subthalamic
nucleus in non-motor functions is needed. The main goal of
this study is to characterize anatomical circuits modulated
by subthalamic deep brain stimulation, and infer about the
inner organization of the nucleus in terms of motor and
non-motor areas. Given its small size and anatomical
intersubject variability, functional organization of the
subthalamic nucleus is difficult to investigate in vivo with
current methods. Here, we used local field potential
recordings obtained from 10 patients with Parkinson's
disease to identify a subthalamic area with an analogous
electrophysiological signature, namely a predominant beta
oscillatory activity. The spatial accuracy was improved by
identifying a single contact per macroelectrode for its
vicinity to the electrophysiological source of the beta
oscillation. We then conducted whole brain probabilistic
tractography seeding from the previously identified
contacts, and further described connectivity modifications
along the macroelectrode's main axis. The designated
subthalamic 'beta' area projected predominantly to motor and
premotor cortical regions additional to connections to
limbic and associative areas. More ventral subthalamic areas
showed predominant connectivity to medial temporal regions
including amygdala and hippocampus. We interpret our
findings as evidence for the convergence of different
functional circuits within subthalamic nucleus' portions
deemed to be appropriate as deep brain stimulation target to
treat motor symptoms in Parkinson's disease. Potential
clinical implications of our study are illustrated by an
index case where deep brain stimulation of estimated
predominant non-motor subthalamic nucleus induced hypomanic
behaviour.},
