Light‐Activated Pharmacological Tools for Exploring the Cholinergic System

open access: yesMedicinal Research Reviews, Volume 45, Issue 4, Page 1251-1274, July 2025.
ABSTRACT Cholinergic transmission plays a critical role in both the central and peripheral nervous systems, affecting processes such as learning, memory, and inflammation. Conventional cholinergic drugs generally suffer from poor selectivity and temporal precision, leading to undesired effects and limited therapeutic efficacy. Photopharmacology aims to
