Bilateral lesions of the striatum induced with 6-hydroxydopamine abolish apomorphine-induced yawning in rats. 1985

C T Dourish, and P H Hutson

The subcutaneous injection of 0.1 mg/kg apomorphine induced a syndrome consisting of yawning, chewing and sexual arousal in male rats. Bilateral lesions of the striatum induced with 6-hydroxydopamine abolished the drug-induced yawning, chewing and sexual arousal and produced a 58% depletion of the concentrations of dopamine in the striatum. These data suggest that apomorphine-induced yawning is mediated by presynaptic dopamine receptors (which may be autoreceptors). Furthermore, it appears that dopaminergic innervation of the striatum may play an important role in the production of yawning elicited by small doses of dopamine agonists.

D012018	Reflex	An involuntary movement or exercise of function in a part, excited in response to a stimulus applied to the periphery and transmitted to the brain or spinal cord.
D003342	Corpus Striatum	Striped GRAY MATTER and WHITE MATTER consisting of the NEOSTRIATUM and paleostriatum (GLOBUS PALLIDUS). It is located in front of and lateral to the THALAMUS in each cerebral hemisphere. The gray substance is made up of the CAUDATE NUCLEUS and the lentiform nucleus (the latter consisting of the GLOBUS PALLIDUS and PUTAMEN). The WHITE MATTER is the INTERNAL CAPSULE.

D003891	Desipramine	A tricyclic dibenzazepine compound that potentiates neurotransmission. Desipramine selectively blocks reuptake of norepinephrine from the neural synapse, and also appears to impair serotonin transport. This compound also possesses minor anticholinergic activity, through its affinity to muscarinic receptors.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D001058	Apomorphine	A derivative of morphine that is a dopamine D2 agonist. It is a powerful emetic and has been used for that effect in acute poisoning. It has also been used in the diagnosis and treatment of parkinsonism, but its adverse effects limit its use.

D016627	Oxidopamine	A neurotransmitter analogue that depletes noradrenergic stores in nerve endings and induces a reduction of dopamine levels in the brain. Its mechanism of action is related to the production of cytolytic free-radicals.	6-Hydroxydopamine,6-OHDA,Oxidopamine Hydrobromide,Oxidopamine Hydrochloride,6 Hydroxydopamine,Hydrobromide, Oxidopamine,Hydrochloride, Oxidopamine
