Pons pathway
WebThe spinothalamic tract (STT) is the main pathway for information from receptors signaling pain and temperature (Willis and Westlund, 1997 ). Several groups of STT neurons can be distinguished, including cells in medial laminae 4–6 and lateral laminae 7–9 ( Granum, 1986; Kemplay and Webster, 1986; Kobayashi, 1998 ). WebThe corticobulbar tract is composed of the upper motor neurons of the cranial nerves.The muscles of the face, head and neck are controlled by the corticobulbar system, which terminates on motor neurons within brainstem motor nuclei. Contrast this to the corticospinal tract were the cerebral cortex connects to spinal motor neurons, and …
