Neurons in the caudal pedunculopontine nucleus, an area of the brain that regulates motor coordination, switch neurotransmitters from acetylcholine to GABA as a result of exercise. The switch appears to provide feedback control that regulates motor coordination and skill learning.
Researchers have identified a mechanism within the cholinergic system that underlies our ability to rapidly focus attention.
In lower mammals, the iris may sense light and cause the pupils to constrict without involving the brain, a new study reports.
Researchers have identified a signaling pathway that promotes sensory neuron grown and prevents peripheral neuropathy when blocked.
According to researchers, traumatic memories are strengthened by an increased release of acetylcholine in the amygdala. Decreasing acetylcholine signaling during traumatic experience helped wipe out memory.
Acetylcholine regulates glutamate signaling in the habenula, reinforcing nicotine addiction, researchers report.
According to a new study, acetylcholine acts via a single neuron type to enable effective information processing.
Researchers create new and specific memories by directly manipulating brain cells in the cerebral cortex of rodents.
Using a line of genetically modified mice, researchers discover boosting acetylcholine can disturb cognitive function.
