Lesions of the dorsal column nuclei or medial lemniscus of the cat: effect on motor performance.
Motor performance in cats was evaluated by means of a beam-walking task after bilateral lesions were made in dorsal column nuclei (DCN) or medial lemniscus (ML) near its entrance to thalamus. Coordinated motor activity was not significantly impaired by ML lesions or by DCN lesions limited to the main nuclei, but was impaired by larger lesions to DCN that also involved the external cuneate nuclei.
