Abstract
In this issue of Brain two studies using different techniques report novel findings on the pathophysiology of focal dystonias. The first paper (Dresel et al., 2006) reports a functional MRI (fMRI) study in patients with cranial dystonia during a whistling task and the second (Fiorio et al., 2006) describes the results of a study on mental body rotation in patients with writer's cramp. Both papers open interesting new questions for further study.
