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 PREFRONTAL CORTEX is considered to be a key cortical substrate of the highest-level mental processes

THE PREFRONTAL CORTEX is considered to be a key cortical substrate of the highest-level mental processes. Yet, despite the bewildering gamut and complexity of cognitive processes that depend on the prefrontal cortex, over the last decades significant progress has been made in linking the prefrontal function with its cellular and circuit mechanisms in a field at the interface between cognitive sciences and cellular electrophysiology. A landmark paper that helped usher prefrontal research into neurophysiology is Funahashi, Bruce, and Goldman-Rakic's article published in 1989 in the Journal of Neurophysiology (3Go).
