This approach overemphasized correlation of histoloogical receptor type with sensory experience.
Upper limbs are lateral in cuneate tract.
There is a cross-over, and then the next nucleus is in the thalamus. 9.3A spinothalamic with synapse and decussation at entry point. There are separate tracts in spinal cord. The lateral portion is for pain and temperature. A half spinal cord injury would cause contralateral loss of spinothalamic below injury and ipailateral loss of lemniscal.
