Somatotopy of the Gracile, Cuneate, External Cuneate Nuclei, Sensory Pathway (Medial Lemniscus, Anterolateral System or Spinal Lemniscus) and Motor Pathway (Corticospinal and Corticobulbar Tracts)

Our previous studies concern the somatotopy of the spinal cord, the oculomotor and trigeminal complexes, the facial nuclei, thus in this review we extend the study to the somatotopy of the nuclei of the origin of the sensory pathways (medial lemniscus, anterolateral system or spinal lemniscus), the origin and course of the motor pathways (corticospinal an corticobulbar tracts) The study shows that lesions of sensory and motor tracts induce clinical aspects related to the level at which the lesion occurs. The knowledge of the origin and pathways is important to understand some neurological clinical and surgical aspects.
