Acetylcholine (Hippocampus) (ACh (Hippocampus))

The level of acetylcholine within the hippocampus serves as a crucial regulator for cognitive processing—including learning/memory—as well as emotional responses under stress. Its actions are mediated through diverse receptor subtypes expressed across multiple cell types. Both excessive increases and decreases are implicated in neuropsychiatric dysfunctions including impaired neurogenesis, anxiety disorders, depression-like behaviors.

Varies depending on the specific drug and receptor involved. Acetylcholinesterase inhibitors increase ACh levels by preventing its breakdown. Muscarinic and nicotinic receptor ligands directly activate or block these receptors, modulating downstream signaling pathways.
