1. Cholinergic chemicals decouple the extensive networks used for cognition and behavior.2. Mefloquine alters cholinergic synaptic transmission through both postsynaptic and presynaptic actions. 3. Cholinergic drugs are drugs that primarily act on the neurotransmitter acetylcholine.4. This is why the eyelids get heavy when cholinergic signals take over. 5. Caffeine also affects the cholinergic system where it inhibits the enzyme acetylcholinesterase. 6. If the endothelium is damaged, cholinergic stimulation causes vasoconstriction. 7. Very few parts of the sympathetic system use cholinergic receptors. 8. COPIND occurs without cholinergic symptoms and is not dependent on AChE inhibition. 9. This process would increase the acetylcholine levels and would have cholinergic effects. 10. He suggested that poets may be more naturally cholinergic .
