Cholinergic neuron - Wikipedia
A cholinergic neuron is a nerve cell which mainly uses the neurotransmitter acetylcholine (ACh) to send its messages. Many neurological systems are cholinergic. Cholinergic neurons provide the primary source of acetylcholine to the cerebral cortex, and promote cortical activation during both wakefulness and rapid eye movement sleep. [1]
Cholinergic Neuron - an overview | ScienceDirect Topics
Cholinergic neurons synthesize the neurotransmitter acetylcholine to send messages throughout the nervous system. Cholinergic neurons originate from the basal forebrain, striatum, thalamic nuclei, and brainstem (Mesulam et al., 1983; …
14.4A: Cholinergic Neurons and Receptors - Medicine LibreTexts
In the central nervous system, acetylcholine and its associated neurons form the cholinergic system. When acetylcholine binds to acetylcholine receptors on skeletal muscle fibers, it opens ligand-gated sodium channels in the cell membrane.
Acetylcholine as a neuromodulator: cholinergic signaling shapes …
2012年10月4日 · We propose that the role of ACh as a neuromodulator in the brain is to increase neurotransmitter release in response to other inputs, to promote burst firing and/or suppress tonic firing, depending upon the system and the neuronal subtypes stimulated. Further, ACh contributes to synaptic plasticity in many brain areas.

2023年2月23日 · Studies that have mapped the activity and functional connectivity of cholinergic neurons have shown that the axons of basal forebrain cholinergic neurons innervate the pallium with far more...
New Insights Into Cholinergic Neuron Diversity - Frontiers
2019年8月26日 · Cholinergic neurons comprise a small population of cells in the striatum but have fundamental roles in fine tuning brain function, and in the etiology of neurological and psychiatric disorders such as Parkinson’s disease (PD) or schizophrenia.
The Cholinergic System - Chemical Biology of Neurodegeneration …
2019年8月9日 · The cholinergic system is located in both the central and peripheral nervous systems. This chapter focuses on the structure and function of all different assemblies involved in acetylcholine neurotransmission at the central nervous system (CNS) level.
Cholinergic - Definition, Effects and Drugs - Biology Dictionary
2019年10月4日 · Cholinergic is a term used to refer to the molecule acetylcholine. It is usually employed to define neurons, receptors or synapses that use acetylcholine. For instance, a cholinergic neuron is a neuron that releases acetylcholine, and a cholinergic receptor is a receptor to which acetylcholine binds. Acetylcholine is a signal molecule in the ...
