Mehanna R, Jankovic J. Movement disorders in cerebrovascular disease. Lancet Neurol 2013; 12: 597—608—In this Review, the section of the figure showing a circuit diagram for hyperkinesias contained several errors. The thick red arrow between STN and GPe should have been a thin red arrow, the thin blue arrow between STN and GPi should have been a thin red arrow, and the thin blue arrow between GPe and GPi should have been a thick blue arrow. This section of the figure has been replaced with a corrected diagram (shown) in the online version as of July 15, 2013.
STN=subthalamic nucleus. GPi=globus pallidus pars interna. GPe=globus pallidus pars externa. SNc=substantia nigra pars compacta. TH=thalamus. SNr=substantia nigra pars reticulata. D1=dopamine receptor D1. D2=dopamine receptor D2.
