The role of the cingulate cortex in the generation of motor tics and the experience of the premonitory urge-to-tic in Tourette syndrome

This study investigates the role of the cingulate cortex in motor tics and premonitory urges in Tourette syndrome using structural brain imaging.

Somatomotor cortical representations are predicted by levels of short-interval intracortical inhibition

The paper uses TMS to show that levels of short-interval intracortical inhibition predict the location and variability of the FDI somatomotor representation in healthy volunteers.
