| **Title** | **Comment** |  |:----------|:------------|  |Dopamine receptors and motor response inhibition\citep{}|Stop-signal reaction time was negatively correlated with D1- and D2-type activation in the dorsal striatum, dorsal,  but not the ventral ventral,  striatum. No significant correlations involving the continuous performance task were found suggesting that different inhibitory mechanisms are involved in these two tasks.  Compare also \citep{25562824}. | |Motor execution and motor imagery \cite{26566185}|An exploratory study found neural hyperactivation for both types of tasks when TS adults were compared to controls. Interestingly, the exception to this was that basal ganglia and thalamic activation was smaller in the TS subjects than the controls. Premotor activation during the motor imagery tasks was correlated with tic severity. |  |  |Sensorimotor cortex and insula\citep{26538289}. |More intense premonitory urges were associated with thinning in these areas.|
