History

Vesalius and Piccolomini in 16th century distinguished subcortical nuclei from cortex and white matter. However Willis' conceptualized the corpus striatum as the seat of motor power in the late 17th century. In mid-19th-century movement disorders were localized to striatum by Choreaby Broadbent and Jackson, and athetosis by Hammond. By the late 19th century, many movement disorders were described, but for most no pathologic correlate was known.^[9]
