In contrast, the nitrergic pathway releases NO and favors inhibition, opposing the contractile properties of the LES. Overall, the combination of these forces favors contraction over ... 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 … See more Most research involving cholinergic neurons involves the basal forebrain cholinergic neurons. However, cholinergic neurons only represent about 5% of the total basal forebrain cell population. Most of these neurons … See more Normal aging is described as aging unaccompanied by the behavioral or cognitive dysfunctions associated with the cholinergic basal forebrain system. In normal aging, there are beadlike swellings within the cholinergic fibers with enlarged or thickened See more Cholinergic neurons, along with non-cholinergic neurons, have sleep/wake regulatory functions in the basal forebrain that can be categorized based on their firing patterns in different regions. The cholinergic system allows the circadian system to … See more Nerve growth factor protects cholinergic neurons.
