Yes! Very relevant indeed!

Here's just one of the many examples of how ACh is involved in improving signal-to-noise ratio:
 

The traditional view that derangements of the basal forebrain cholinergic system in Alzheimer's disease relate specifically to memory impairment is assessed in terms of a more general role for cortical acetylcholine in consciousness. This extends the concept that cortical acetylcholine enhances neuronal signal to noise ratio. It is suggested that muscarinic receptor activation in the cortex is involved in confining the contents of the discrete self-reported conscious "stream." In the absence of cortical acetylcholine, currently irrelevant intrinsic and sensory information, which is constantly processed in parallel at the subconscious level, enters conscious awareness. This is consistent with the ability of anti-muscarinic drugs administered medically, recreationally, or ritualistically to induce visual hallucinations and other perceptual disturbances.

This is one of the reasons why recently I've been putting so much faith in Coluracetam!
