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.

The role of norepinephrine in spatial reference and spatial working memory

The role of norepinephrine in spatial reference and spatial working memory

The adrenergic system (utilizing norepinephrine, NE, as a neurotransmitter) is implicated in hippocampus-based learning and memory, in addition to its well known peripheral actions mediated by the sympathetic nervous system.
