It doesn’t. It stays on the ipsilateral side of body
Where does the spinothalamic tract decussate?
About 1-3 vertebral segments above the level

Arises from left intercostal or lumbar artery at levels of T9-L3
What part of cerebral cortex do the dorsal columns, corticospinal and spinothalamic tracts attach to
