WebSpinothalamic tract (anterolateral system) The spinothalamic tract has two components, often referred to collectively as the anterolateral system. They are the anterior and lateral spinothalamic tracts (STT): Anterior STT: crude touch and pressure. Lateral STT: pain and temperature. The pathway of the spinothalamic tracts is shown in the table 2. The spinothalamic tract is a part of the anterolateral system or the ventrolateral system, a sensory pathway to the thalamus. From the ventral posterolateral nucleus in the thalamus, sensory information is relayed upward to the somatosensory cortex of the postcentral gyrus.
