Notes: | |||
*Histologically identical to the ''caudate'' - but not adjacent to a ventricle. | |||
**The caudate is adjacent to an ependymal lined space, putamen is not.<ref>URL: [http://www.stonybrookmedicalcenter.org/pathology/neuropathology/chapter1 http://www.stonybrookmedicalcenter.org/pathology/neuropathology/chapter1]. Accessed on: 22 December 2010.</ref> | |||
