1 Release was monitored by measuring endogenous ACh when acetylcholinesterase (AChE) was inhibited with physostigmine (30 microM) or by measuring endogenous choline when AChE activity was left intact. Acetylcholine acetylcholinesterase Rattus norvegicus
2 Release was monitored by measuring endogenous ACh when acetylcholinesterase (AChE) was inhibited with physostigmine (30 microM) or by measuring endogenous choline when AChE activity was left intact. Physostigmine acetylcholinesterase Rattus norvegicus
3 Release was monitored by measuring endogenous ACh when acetylcholinesterase (AChE) was inhibited with physostigmine (30 microM) or by measuring endogenous choline when AChE activity was left intact. Physostigmine acetylcholinesterase Rattus norvegicus
4 Release was monitored by measuring endogenous ACh when acetylcholinesterase (AChE) was inhibited with physostigmine (30 microM) or by measuring endogenous choline when AChE activity was left intact. Choline acetylcholinesterase Rattus norvegicus
5 The classical antagonist, atropine (0.1-2 microM), induced an increase in release whether AChE activity was inhibited or intact. Atropine acetylcholinesterase Rattus norvegicus
6 The putative M-1 selective antagonist, pirenzepine, had minimal effects over a broad concentration range (2-200 microM) and induced an increase in ACh release only when AChE activity was inhibited. Pirenzepine acetylcholinesterase Rattus norvegicus
7 The classical agonist, oxotremorine (10-100 microM) decreased effectively ACh release (by 22-35%), but only when AChE activity was intact. Oxotremorine acetylcholinesterase Rattus norvegicus
8 The oxotremorine analog, oxotremorine-M, was apparently more potent than oxotremorine, but also decreased ACh release (by 24-41%) only when AChE activity was intact. Oxotremorine acetylcholinesterase Rattus norvegicus
9 The oxotremorine analog, oxotremorine-M, was apparently more potent than oxotremorine, but also decreased ACh release (by 24-41%) only when AChE activity was intact. Oxotremorine acetylcholinesterase Rattus norvegicus
10 The oxotremorine analog, oxotremorine-M, was apparently more potent than oxotremorine, but also decreased ACh release (by 24-41%) only when AChE activity was intact. Oxotremorine acetylcholinesterase Rattus norvegicus
11 Another oxotremorine analog, BM-5, behaved more like a muscarinic antagonist in its effects on neostriatal ACh release, and the highest concentration tested (100 microM) increased release (by 47%) when AChE activity was left intact. Oxotremorine acetylcholinesterase Rattus norvegicus
12 Another oxotremorine analog, BM-5, behaved more like a muscarinic antagonist in its effects on neostriatal ACh release, and the highest concentration tested (100 microM) increased release (by 47%) when AChE activity was left intact. N-methyl-N-(1-methyl-4-pyrrolidino-2-butynyl)acetamide acetylcholinesterase Rattus norvegicus
