The amount of compensatory sweating depends on the patient, the damage that the white rami communicans incurs, and the amount of cell body reorganization in the spinal cord after surgery.
Other potential complications include inadequate resection of the ganglia, gustatory sweating, pneumothorax, cardiac dysfunction, post-operative pain, and finally Horner’s syndrome secondary to resection of the stellate ganglion.

After severing the cervical sympathetic trunk, the cells of the cervical sympathetic ganglion undergo transneuronic degeneration
After severing the sympathetic trunk, the cells of its origin undergo complete disintegration within a year.

Where were you on Sept. 11, 20017 Or when the shuttle Challenger exploded in 19867 Heightened emotions cause experiences to crystallize into lasting and vivid memories. This boost in memory formation is due in part to the stress hormone norepinephrine, but scientists haven't understood how the hormone causes this effect.

Now researchers have uncovered molecular changes triggered by norepinephrine that help nerve cells form new memories.

A team led by Roberto Malinow of Cold Spring Harbor Laboratory in New York traced the hormone's effects to a receptor molecule called glutamate receptor 1 (G1uR1) on the surfaces of nerve cells. Through G1uR1 and similar receptors, ... http://www.highbeam.com/doc/1G1-170372501.html
