It’s not unusual to hear people describe themselves as emotionally 'colder'

It’s not unusual to hear people who have undergone sympathectomies describe themselves as feeling emotionally “colder” than before. Among psychologists and neurologists alike there is concern, but no evidence, that the procedure limits alertness and arousal as well as fear, and might affect memory, empathy and mental performance. Professor Ronald Rapee, the director of the Centre of Emotional Health at Sydney’s Macquarie University, says he’s counselled several people who complain of feeling “robot-like” in the long-term wake of the operation. “They’re happy they no longer blush, but they miss the highs and lows they used to feel.”

pituitary secretions of ACTH and TSH after sympathectomy

The present results suggest that cervical sympathectomy in the rat increases ACTH secretion and decreases TSH secretion in the pituitary. These effects seem to be due to a mildly increased secretion of melatonin in the pineal body that probably in turn increases corticotropin-releasing factor (CRF) secretion and decreases thyrotropin-releasing hormone (TRH) secretion in the hypothalamus. Extrapolation of these findings to humans suggests that longterm and repeated stellate ganglion block would affect the pituitary secretions of ACTH and TSH.
