Although total levels of muscarine receptors in the rat forebrain and brainstem are constant at different times of day, there are large circadian changes in the numbers and carbachol-affinities of unoccupied receptors, which appear to reflect varying levels of endogenous acetylcholine-receptor complexes and the activity of cholinergic synapses.
