Pharmacological properties of cholinoceptive neurones in the medulla and pons of the cat

The Journal of Physiology
P B BradleyJ H Wolstencroft


1. Iontophoretic application of acetylcholine to neurones in the medulla and pons of the unanaesthetized decerebrate cat excited 35.5% and inhibited 22%. This was not a representative sample of lower brain stem neurones, since most penetrations were made medially. Some cholinoceptive neurones were in the medial reticular formation.2. The time course of the response to different doses has been described.3. Nicotine and nicotinic agents 1,1-dimethyl-4-phenylpiperazinium iodide (DMPP) and choline phenyl ether (TM1) excited neurones excited by acetylcholine but, with one exception, did not inhibit neurones inhibited by acetylcholine.4. Muscarinic agents mimicked both the excitatory and inhibitory responses to acetylcholine. (+/-)-muscarine and bethanechol (beta-methylcholine carbamate) had a prolonged and powerful inhibitory action.5. Oxotremorine [1-(2-oxopyrrolidino)-4-pyrrolidino-butyne-2] had a long-lasting excitatory action on neurones excited by acetylcholine.6. Eserine and neostigmine potentiated the action of acetylcholine but in addition they had a strong excitatory effect on many brain stem neurones, independently of the action of acetylcholine.7. Excitatory and inhibitory responses to acetylcholine could be antagonized b...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Alzheimer's Disease: MS4A

Variants within the membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease in genome-wide association studies. Here is the latest research on Alzheimer's disease and MS4A.

Pediculosis pubis

Pediculosis pubis is a disease caused by a parasitic insect known as Pthirus pubis, which infests human pubic hair, as well as other areas with hair including eye lashes. Here is the latest research.
