spinothalamictraktio
The spinothalamic tractio, commonly known as the spinothalamic tract, is a major ascending somatosensory pathway that conveys nociceptive, thermal, and crude touch information from the body to the brain. It is part of the anterolateral system and consists of two clinically important components: the lateral spinothalamic tract, carrying pain and temperature, and the anterior (ventral) spinothalamic tract, carrying crude touch and pressure.
Origin and decussation: First-order neurons enter the spinal cord and synapse on second-order neurons in the
Thalamic relay and cortical targets: Most fibers terminate in the ventral posterior lateral nucleus (VPL) of
Clinical relevance: Lesions of the spinothalamic tract typically produce contralateral loss of pain and temperature beginning
