M1 muscarinic receptor

The M1 muscarinic receptor is a type of protein found in the brain that responds to the chemical acetylcholine. It plays a crucial role in cognitive functions such as learning, memory, and attention. When acetylcholine binds to these receptors, it triggers signals that help neurons communicate effectively. M1 receptors are primarily located in nerve cells within areas of the brain involved in thinking and memory. Proper functioning of these receptors is important for mental clarity, and disruptions may be linked to neurological conditions like Alzheimer's disease.
