(October, 2004).Due to an editing error, the final sentence in the published abstract was reproduced incorrectly. The correct sentence is “The role of the pedunculopontine and cuneiform nuclei, and related brainstem structures, in mediating motor activity and controlling muscle tone suggests that alterations in these structures could underlie the pathophysiology of DYT1 dystonia.”

The publishers regret this oversight.
