Larsh et al. \cite{Larsh2023a} used a combined approach to determine whether cortical properties such as excitability (CE) as well as cortical inhibition (LICI) correlate with urges and tics. In line with previous studies, urge intensity correlated with tic scores. Higher urge severity correlated with lower CE and LICI. 
Li et al. \cite{Li2023} published results of the systematic review and meta-analysis investigating relationship between urge severity and neuronal correlates. Altogether, 22 studies were identified with a total of 1236 patients. Results of meta-regression demonstrated that age and tic severity were related to PU severity. From the neuroanatomic perspective, PU was related to the following regions of the brain:  insula, prefrontal cortex, anterior cingulate cortex, and supplementary motor area. 
A study from Japan \cite{Kimura2023} explored the pre-movement gating (attenuation) using  somatosensory evoked potentials (SEPs). Interestingly enough, sensomonitor processing was preserved for simple tics but impaired for complex tics in a group of individuals after middle adolescence.
