| **Title** | **Comment** |  |:----------|:------------|  |  |Dopamine receptors and motor response inhibition \cite{25878272} \Stop-signal \cite{25878272}|Stop-signal  reaction time was negatively correlated with D1- and D2-type activation in the dorsal, but not 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. |  |
