1. Sympathetic and subretrofacial neuron responses to preoptic warming were studied in chloralose- or Saffan-anaesthetized, paralysed cats. 2. Warming a thermode in the preoptic region inhibited the...
Classification of preganglionic neurones projecting into the cat cervical sympathetic trunk.
Boczek-Funcke, A, Dembowsky, K, Häbler, H J, Jänig, W, McAllen, R M, Michaelis, M
1. The spontaneous and reflex activity patterns of 167 single preganglionic axons dissected from the cervical sympathetic trunk were examined in chloralose-anaesthetized cats. Each neurone was...
1. Simultaneous recordings were made from postganglionic sympathetic fibres supplying hindlimb skin and skeletal muscle in chloralose-anaesthetized, artificially ventilated cats. Single-fibre...
Central respiratory modulation of subretrofacial bulbospinal neurones in the cat.
1. Spontaneous activity was recorded from spinally projecting neurones of the subretrofacial nucleus (s.r.f.) in seven chloralose-anaesthetized, vagotomized, paralysed cats. Nineteen such neurones...
In chloralose-anaesthetized, artificially ventilated cats, the effects have been studied of inactivating neurones of the 'glycine-sensitive area' of the rostral ventrolateral medulla on evoked renal...
Two types of vagal preganglionic motoneurones projecting to the heart and lungs
1. A study has been made of eighty-four cells in the cat's nucleus ambiguus whose axons projected to the cardiac (seventy-four) and pulmonary (ten) branches of the right vagus. Their axonal...
The baroreceptor input to cardiac vagal motoneurones
1. A study has been made of twenty-three cardiac vagal motoneurones (c.v.m.s) in the nucleus ambiguus of chloralose-anaesthetized cats.
The carotid chemoreceptor input to the respiratory neurones of the nucleus of tractus solitarius
Lipski, J., McAllen, R. M., Spyer, K. M.
1. An investigation has been made into the connexions between the carotid body chemoreceptors and the dorsal respiratory neurones of the cat's medulla.
The location of cardiac vagal preganglionic motoneurones in the medulla of the cat.
1. Electrophysiological techniques have been used to locate the origin of preganglionic vagal motoneurones supplying the heart of the cat. 2. The right cardiac vagal branches were identified...
Humphreys, P. W., Joels, N., McAllen, R. M.
1. The effects of stimulation of the hypothalamic defence area on carotid sinus baroreceptor reflexes have been investigated by examining the cardiovascular responses to a 15 sec period of increased...
The sinus nerve and baroreceptor input to the medulla of the cat.
Lipski, J, McAllen, R M, Spyer, K M
Electrical stimulation within the medulla of cats revealed that myelinated primary afferent fibres of the sinus nerve terminated within the immediate vicinity of the tractus solitarius and its...

Cold-activated raphé-spinal neurons in rats
Rathner, J A, Owens, N C, McAllen, R M
In a search for sympathetic premotor neurons subserving thermoregulatory functions, medullary raphé-spinal neurons were studied in urethane-anaesthetized, artificially ventilated, paralysed rats....
Thermoregulatory control of sympathetic fibres supplying the rat's tail
Owens, N C, Ootsuka, Y, Kanosue, K, McAllen, R M
We investigated the thermoregulatory responses of sympathetic fibres supplying the tail in urethane-anaesthetised rats. When skin and rectal temperatures were kept above 39 °C, tail sympathetic...
