(a) Ablation of the cerebellum, midbrain, hypothalamus, pituitary, diencephalon, and telencephalon. (b) Section of the posterior cervical roots from Cl to C6. (c) Section of the spinal cord at C6. (d) Section of the two vagus nerves and of the sino-aortic nerves. (e) Ablation of the two stellate ganglia. (f) Splanchnicectomy and medullo-adrenal curettage.
