Inhibition of shaking movements in rats by central administration of cholinergic and adrenergic agents
Abstract:
Shaking movements of the body, similar to that made by a dog when wet ('wet-dog shakes'), occur in rats in response to pharmacological stimuli and in response to stimuli associated with cold and skin irritation. In this study, shaking movements, elicited by a variety of stimuli, were inhibited by central administration of nanomolar doses of drugs that act as agonists on muscarinic, adrenergic, and opiate receptors. The brain regions that mediate the drug inhibition of shaking appear to be located in the medial preoptic area and in structures lining the aqueduct and fourth ventricle.

Indirect-Acting Cholinergic Agonists: Mechanism of Action
Reversible inhibitors like edrophonium bind to a specific part of the enzyme called the anionic catalytic site. They form noncovalent bonds, which means they are not strongly attached to the enzyme. This creates a temporary and less stable enzyme–inhibitor complex, leading to...

At the neuromuscular junction, these agents work by inhibiting the breakdown of acetylcholine, allowing it to remain bound to the receptor and bind to nearby receptors. This process leads to repetitive firing of the endplate, causing muscle...

Adrenergic Agonists: Indirect-Acting Agents
One mechanism involves depleting stored catecholamines by displacing them from synaptic vesicles. These agents, known as "displacers," are transported into vesicles at the expense of noradrenaline. Examples include amphetamine and tyramine, which lack a catechol moiety, resulting in prolonged action, improved oral bioavailability, and...
