|  |Event-related topography and the effect of comorbidities \citep{Germain_2015}|P300 amplitude in the frontal region was reduced for TS patients with comorbid symptoms compared to control subjects while a medication-naive TS group with no comorbid conditions was similar to the control group  |  |Magnetoencehalography and beta rhythms \cite{26649991}. TS |TS  adults exhibited less beta suppression in the sensorimotor region and increased beta power in parieto-occipital brain regions during a Go/NoGo task with YGTSS motor scores negatively correlated with average beta power and beta power increases over time suggesting that compensatory mechanisms to control tics might involve both increased motor inhibitory processes and visuomotor attentional processes.| ### Clinical and neuropsychological studies
