Medulla oblongata of 80 vagotomized cats was explored with microelectrodes. Spontaneous respiratory neuronal activities and chest movements were recorded simultaneously with a twin beam cathode ray oscilloscope. It was found that inspiratory discharges are concentrated in the reticular formation between 3 mm rostral and 1 mm caudal to the level of the obex, which corresponds approximately to the inspiratory region of Pitts, Magoun and Ranson. On the other hand, expiratory discharges are not obtained in Pitts' expiratory area, but are found in a circumscribed region in the reticular formation from the level of the obex to 3 mm caudally. Electric stimulation of this region has been found recently by Ngai and Wang to yield marked expiratory spasm. It is concluded that the expiratory center is located caudally to the inspiratory center in the cat. The spontaneous respiratory neuronal discharges continue with no alterations of pattern of firing during drug-induced respiratory paralysis, and are increased both in number and in frequency during CO2 inhalation. Stimulation of the vagus nerve with 50 shocks/sec. reduces inspiratory discharges and prolongs the duration of expiratory discharges.

Abstract: This paper addresses the importance of steady state brain oscillation for brain connectivity and cognition. Given that a healthy brain maintains particular levels of oscillatory activity, it argues that disturbances or dysrhythmias of this oscillatory activity can be implicated in common health conditions including Alzheimer’s disease, Parkinson’s Disease, pain, and depression. Literature is reviewed that shows that electric stimulation of the brain can contribute to regulation of neural oscillatory activity and the alleviation of related health conditions. It is then argued that specific frequencies of sound in their vibratory nature can serve as a means to brain stimulation through auditory and vibrotactile means and as such can contribute to regulation of oscillatory activity. The frequencies employed and found effective in electric stimulation are reviewed with the intent of guiding the selection of sound frequencies for vibroacoustic stimulation in the treatment of AD, PD, Pain, and depression.

Vagal nerve stimulation and electroacupuncture have some promise as neuroprotective therapies for patients with poorly controlled epilepsy. It has been demonstrated that stimulation of acupuncture points on the extremities results in stimulation of the vagus nerve. It is possible that the antiepileptic effects of these two applications might be targeting the same centre in the brain. The nucleus of the solitary tract, which is a primary site at which vagal afferents terminate, is also the site for afferent pathways of facial, scalp and auricular acupuncture via trigeminal, cervical spinal and glossopharyngeal nerves. Taken together with laboratory findings, the neuroprotective pathways of electroacupuncture in epileptic models may stem from the collaboration of its anti-inflammatory and neurotrophic actions through the nucleus of the solitary tract via vagus nerve stimulation.

In dogs, the central end of the cut phrenic or vagus nerve was anastomosed to the distal end of the phrenic nerve. After phreno-phrenic anastomosis, slight atrophy of the muscle and nerve elements of the diaphragm occurred up to 7–8 weeks, followed by regeneration. At that time, electric stimulation of the nerve above the anastomosis produced contraction of the diaphragm, although respiratory function was absent. Ten to eleven weeks after anastomosis, spontaneous respiration recurred. In the case of vagophrenic anastomosis, spontaneous respiration did not reappear within 58 weeks, but stimulation of the vagus above the anastomosis produced contraction of the diaphragm, and histologic study showed regeneration of muscle and nerve elements. It is concluded, that trophic maintenance of the diaphragm depends on the presence of functionable innervation, not necessarily on functioning innervation.
