In anterior cord syndrome, which sensory modality is lost at the level of the lesion?

Explanation:
Anterior cord syndrome damages the anterior two-thirds of the spinal cord, where the spinothalamic tract (pain and temperature) and the corticospinal tract reside, while the dorsal columns (vibration and proprioception) are preserved. Because the injury affects the anterior portion, pain and temperature sensation is lost at the level of the lesion (and below), whereas fine touch and vibratory/proprioceptive sense remain intact. Hearing is outside the spinal cord pathways, so it is unaffected. Thus, the sensory modality lost at the level of the lesion is pain and temperature.
