The effects of opiate agonists on acetylcholine release from hippocampal, striatal and
cerebral cortical slices were tested; tissue from rat was compared to that from guinea-pig …

The effects of intraventricular injections of alpha-endorphin, beta-endorphin and morphine
have been studied on the tail flick test, on catalepsy and on acetylcholine turnover rate in …

The effects of various opioid receptor agonists and antagonists on evoked acetylcholine
release were studied in slices of human neocortex prelabelled with [3 H]-choline …

Endogenous acetylcholine (ACh) release from rat striatal slices was measured by a
chemiluminescent method. Several opiate agents were tested for their ability to modulate …

Slices of the rabbit hippocampus were pre-incubated with 3 H-choline, rinsed and
superfused continuously. The release of 3 H-acetylcholine in these slices, evoked by …

We investigated the effect of selective opiate antagonists on striatal acetylcholine (ACh) and
dopamine (DA) release. The μ-receptor antagonist β-funaltrexamine (β-FNA), the δ …

Recently we demonstrated specific binding of opiate agonists and antagonists to the
pharmacologically relevant opiate receptor in the brains of several mammalian species s, 9 …

Intraseptal administration of morphine (70 nmol) or β-endorphin (0.7 nmol) reduced the rate
of acetylcholine (ACh) turnover (TR ACh) in rat hippocampus but not in striatum or cortex …

Modulation of acetylcholine release was studied in slices of the rabbit hippocampus
preincubated with 3 H-choline and then continuously superfused with a medium containing …

Summary The effect of morphine (0.5–50 μM) was examined on CA1 field potentials in the
transverse hippocampal slice. Morphine consistently produced an augmentation of evoked …
