Easy! Spinothalamic which carries pain and temperature sensation, and it crosses the middle line inmediately, so deficit presents usually 1-2 segments below the lesion. IM SO HAPPY I REMEMBER!!!

right, D)Spinothalamic tracts
There are 2 pathways that together form the anterolateral system - the lateral spinothalamic tract which carries the modalities of pain and temperature, and the anterior spinothalamic tract which carries the modality of crude touch and other sensations not known for accurate localization (itch, tickle, sexual).
