Data indicate the numbers of mRNA molecules for individual muscarinic receptor subtypes (mean ± S.E. of three determinations) per 1 ng of total cerebrocortical RNA, and the proportions (percentage) that mRNAs for individual subtypes represent of the sum of mRNAs for all subtypes of muscarinic receptors taken together.
