He is brought to a hospital and subjected to a radical treatment which cuts the nerves of the spinothalamic tract, so physical pain is no longer felt.
22.
The zona incerta receives pain input through the spinothalamic tract and this has been shown to control the activity of the pain transmission pathway in the posterior thalamus.
23.
The spinothalamic tract, like the dorsal column-medial lemniscus tract, uses three neurons to convey sensory information from the periphery to conscious level at the cerebral cortex.
24.
SP, a hybrid neurotransmitter-cytokine, is co-transmitted with BDNF through paleo-spinothalamic circuitry from the periphery with collaterals into key areas of the limbic system.
25.
Cordotomy involves cutting into the spinothalamic tracts, which run up the front / side ( anterolateral ) quadrant of the spinal cord, carrying heat and pain signals to the brain.
26.
The peduncle is not part of the lateral-spinothalamic-tract-pathway; the medulla receives the info and passes it onto the peduncle from elsewhere ( see somatosensory system ).
27.
There are two main parts : the lateral spinothalamic tract, which transmits pain and temperature, and the anterior ( or ventral ) spinothalamic tract, which transmits crude touch and pressure.
28.

29.
The spinothalamic tract thus decussates very soon after entering the spinal cord, ascending in the spinal cord, contralateral to the side from where it provides ( pain and temperature ) sensory information.
30.
Unmyelinated nerve fibers for itch and pain both originate in the skin; however, information for them is conveyed centrally in two distinct systems that both use the same nerve bundle and spinothalamic tract.
