The in vitro autoradiographic technique was used to characterize the density and laminar
distribution of muscarinic cholinergic receptors in 12 cytoarchitectonic areas in the frontal …

The regional distributions of muscarinic receptor subtypes (M1 and M2) in the macaque
brain were investigated by in vitro receptor autoradiography. Putative muscarinic receptor …

The distribution and characteristics of M 1 and M 2 muscarinic cholinergic receptors as
defined by their affinity for the antagonist pizenzepine were studied in the human brain using …

The distribution of muscarinic cholinergic receptors in the human forebrain and cerebellum
was studied in detail by quantitative autoradiography using N-[3H] methylscopolamine as a …

The distribution of high vs. low affinity muscarinic agonist binding sites has been determined
using quantitative techniques of receptor autoradiography. The low affinity agonist sites …

The affinities of muscarinic agonists and antagonists were determined by autoradiography
and image analysis in selected areas of the rat brain. IC 50 values and Hill coefficients for …

Previous studies have shown that muscarinic cholinergic agonists bind to 3 distinct receptor
sites in brain, each being distinguished by their affinity for the agonists. Antagonists, on the …

Several neurophysiological studies have attempted to differentiate the relative
preponderance of nicotinic or muscarinic cholinergic receptors in different brain areas1, 16 …

The binding characteristics of N [3 H] methylscopolamine (3 H] NMS) to slide-mounted tissue
sections were studies using quantitative autoradiography. Binding of [3 H] NMS was …

Light microscopic autoradiography of [3H] quinuclidinyl benzilate (QNB) binding sites was
used to study the distribution of muscarinic acetylcholine receptors in the mouse, rat, guinea …
