Quantitative electrocortical changes in the rat induced by phencyclidine and other stimulants. 1985

H Neal, and A Bond

An automated technique for the continuous analysis of different frequency bands of the electrocorticogram (ECoG) of the rat has been used to quantify the actions of phencyclidine (PCP) and various other stimulant drugs. It has been demonstrated that phencyclidine, etoxadrol and LY154045 produced similar changes in the individual frequency bands whereas amphetamine and apomorphine had different profiles of activity. The phencyclidine-like compounds exhibited extremely strong stimulation of the ECoG with very large increases recorded in high frequency (15-50 Hz) activity and reductions in all other frequency bands. Various compounds have been used in an attempt to antagonise the changes in the ECoG. Chlorpromazine caused a slight shift in the dose-response curves as did chlordiazepoxide when used with phencyclidine. The GABA agonists, THIP and muscimol, had no effect on the stimulation of the ECoG. In contrast another presumed GABA agonist, baclofen, proved to be the most effective agent for blocking the stimulation induced by phencyclidine. The role of the GABAB receptor in the action of phencyclidine is discussed.

UI	MeSH Term	Description	Entries
D007546	Isoquinolines	A group of compounds with the heterocyclic ring structure of benzo(c)pyridine. The ring structure is characteristic of the group of opium alkaloids such as papaverine. (From Stedman, 25th ed)
D007555	Isoxazoles	Azoles with an OXYGEN and a NITROGEN next to each other at the 1,2 positions, in contrast to OXAZOLES that have nitrogens at the 1,3 positions.	Isoxazole
D008297	Male		Males
D009118	Muscimol	A neurotoxic isoxazole isolated from species of AMANITA. It is obtained by decarboxylation of IBOTENIC ACID. Muscimol is a potent agonist of GABA-A RECEPTORS and is used mainly as an experimental tool in animal and tissue studies.	Agarin,Pantherine
D010622	Phencyclidine	A hallucinogen formerly used as a veterinary anesthetic, and briefly as a general anesthetic for humans. Phencyclidine is similar to KETAMINE in structure and in many of its effects. Like ketamine, it can produce a dissociative state. It exerts its pharmacological action through inhibition of NMDA receptors (RECEPTORS, N-METHYL-D-ASPARTATE). As a drug of abuse, it is known as PCP and Angel Dust.	1-(1-Phenylcyclohexyl)piperidine,Angel Dust,CL-395,GP-121,Phencyclidine Hydrobromide,Phencyclidine Hydrochloride,Sernyl,Serylan,CL 395,CL395,Dust, Angel,GP 121,GP121
D011919	Rats, Inbred Strains	Genetically identical individuals developed from brother and sister matings which have been carried out for twenty or more generations or by parent x offspring matings carried out with certain restrictions. This also includes animals with a long history of closed colony breeding.

D002540	Cerebral Cortex	The thin layer of GRAY MATTER on the surface of the CEREBRAL HEMISPHERES that develops from the TELENCEPHALON and folds into gyri and sulci. It reaches its highest development in humans and is responsible for intellectual faculties and higher mental functions.

D002707	Chlordiazepoxide	An anxiolytic benzodiazepine derivative with anticonvulsant, sedative, and amnesic properties. It has also been used in the symptomatic treatment of alcohol withdrawal.	Methaminodiazepoxide,7-Chloro-2-methylamino-5-phenyl-3H-1,4-benzodiazepine-4-oxide,7-Chloro-N-methyl-5-phenyl-3H-1,4-benzodiazepin-2-amine 4-oxide,Chlordiazepoxide Hydrobromide,Chlordiazepoxide Hydrochloride,Chlordiazepoxide Monohydrochloride,Chlordiazepoxide Perchlorate,Chlozepid,Elenium,Librium,7 Chloro 2 methylamino 5 phenyl 3H 1,4 benzodiazepine 4 oxide,7 Chloro N methyl 5 phenyl 3H 1,4 benzodiazepin 2 amine 4 oxide,Hydrobromide, Chlordiazepoxide,Hydrochloride, Chlordiazepoxide,Monohydrochloride, Chlordiazepoxide,Perchlorate, Chlordiazepoxide
D002746	Chlorpromazine	The prototypical phenothiazine antipsychotic drug. Like the other drugs in this class chlorpromazine's antipsychotic actions are thought to be due to long-term adaptation by the brain to blocking DOPAMINE RECEPTORS. Chlorpromazine has several other actions and therapeutic uses, including as an antiemetic and in the treatment of intractable hiccup.

D003913	Dextroamphetamine	The d-form of AMPHETAMINE. It is a central nervous system stimulant and a sympathomimetic. It has also been used in the treatment of narcolepsy and of attention deficit disorders and hyperactivity in children. Dextroamphetamine has multiple mechanisms of action including blocking uptake of adrenergics and dopamine, stimulating release of monamines, and inhibiting monoamine oxidase. It is also a drug of abuse and a psychotomimetic.	d-Amphetamine,Curban,Dexamfetamine,Dexamphetamine,Dexedrine,Dextro-Amphetamine Sulfate,DextroStat,Dextroamphetamine Sulfate,Oxydess,d-Amphetamine Sulfate,dextro-Amphetamine,Dextro Amphetamine Sulfate,Sulfate, Dextroamphetamine,d Amphetamine,d Amphetamine Sulfate,dextro Amphetamine
