Clarke's column (column of Clarke, dorsal nucleus, posterior thoracic nucleus, nucleus dorsalis of Clarke) is a group of interneurons found in the medial part of Lamina VII, also known as the intermediate zone, of the spinal cord. It is mainly located from the T1 to L3-L4 levels and is an important structure for proprioception.
