WebJan 31, 2024 · Spinothalamic tracts are the ascending tracts present in the spinal cord. An ascending tract is a bundle of nerve fibers that carries signals from the peripheral body parts to the higher centers of the brain. As the name indicates, spinothalamic tracts originate in the spinal cord and terminate in the thalamus, which is a part of the forebrain.

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 ).
