Coordinated Acetylcholine Release in Prefrontal Cortex and Hippocampus Is Associated with Arousal and Reward on Distinct Timescales

Cell Reports, 2017
Cholinergic neurotransmission throughout the neocortex and hippocampus regulates arousal, learning, and attention. However, owing to the poorly characterized timing and location of acetylcholine release, its detailed behavioral functions remain unclear ...

Scanning curves and kinetics of the acetylcholine / acetylcholine receptor hysteresis [PDF]

Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1988
The high affinity binding of the neurotransmitter acetylcholine (AcCh) to the nicotinic acetylcholine receptor (nAcChR) of the electric organ of Torpedo californica exhibits a pronounced hysteresis and scanning loops. Dialysis conditions lead to an equilibrium binding curve which is coincident with the upper hysteresis branch; K = 5 × 10−9M, 4° C; and ...

Conformation of acetylcholine bound to the nicotinic acetylcholine receptor. [PDF]

Proceedings of the National Academy of Sciences, 1988
We report here the biologically active conformation of acetylcholine when bound to the high-affinity state of the receptor from Torpedo californica. The acetylcholine conformation was determined in the free and bound states by proton NMR two-dimensional nuclear Overhauser effects. In agreement with x-ray crystallographic data, acetylcholine in solution
