It is responsible for the transmission of pain, temperature, and crude touch to the somatosensory region of the thalamus. Corticospinal tract - ANSWER A descending tract of the spinal cord which contains bundles of axons which originate in the cerebral cortex and descend to synapse within the brainstem or spinal cord. The neurons are called "upper motor neurons".
