Two distinct profiles of fMRI and neurophysiological activity elicited by acetylcholine in visual cortex [Neuroscience]

Cholinergic neuromodulation is involved in all aspects of sensory processing and is crucial for processes such as attention, learning and memory, etc. However, despite the known roles of acetylcholine (ACh), we still do not how to disentangle ACh contributions from sensory or task-evoked changes in functional magnetic resonance imaging (fMRI)....
