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.

Norephineprine - Emotion - Memory

Dr. Walling studied the contribution of emotion to the formation of memory. Norepinephrine, a neurotransmitter released during states of heightened arousal, is considered to be the primary candidate mediating the effects of emotion on memory. Dr. Walling's study on rats provides support for the hypothesis that that short-term and long-term memory processes may be modulated by separate and distinct memory mechanisms.
