Deficits in cholinergic signaling impair cognition and conscious processing. Nicotinic acetylcholine receptors (nAChRs) play a key role in modulating cognitive behavior and conscious control.
Area of Science:
- Neuroscience
- Cognitive Science
- Molecular Biology
Background:
- Cholinergic signaling deficits are linked to cognitive disorders.
- Nicotinic acetylcholine receptors (nAChRs) are crucial for brain function.
Purpose of the Study:
- To review the role of nAChRs in high-order cognitive processes.
- To discuss the involvement of cholinergic circuits in cognitive control and conscious processing.
Main Methods:
- Literature review of recent studies.
- Integration of molecular approaches, in vivo recordings, human brain imaging, and genetics.
Main Results:
- nAChRs modulate cognitive behavior and network dynamics.
- Cholinergic circuits are implicated in cognitive control and conscious processing.
Conclusions:
- nAChRs are vital for higher-order cognition.
- Understanding cholinergic circuits enhances knowledge of cognitive control.

Drugs Acting on Autonomic Ganglia: Stimulants
Ganglionic stimulants activate NM nicotinic receptors in autonomic ganglia, falling into two categories: nicotine mimetics [e.g., lobeline, dimethylpiperazine, tetramethylammonium] and muscarinic receptor agonists [e.g., muscarine, methacholine]. The first category's action is rapid and blocked by nicotinic receptor antagonists, while the second category's action is delayed and blocked by atropine-like agents. Nicotine, an alkaloid, affects the heart rate by stimulating...
