better knowledge in the transmission of pain signals , clinical analysis of pain allowing its aetiopathogenic interpretation ( neurogenic pain , somatogenic pain ) , and technical improvements in neurosurgical interventions that have now become non-traumatic , increasingly selective with less and less general anaesthesia and without prolonged hospitalization , most often allowing precise postoperative control of the intervention , have given neurosurgery a fresh impetus and a major place in the multidisciplinary therapeutic approach to chronic pain .
