Whole\u2010cell patch clamp recordings were made from nucleus accumbens neurones in slices of rat ventral forebrain. In the presence of picrotoxin (50 microM), the amplitude of 6\u2010cyano\u20107\u2010nitroquinoxaline\u20102, 3\u2010dione\u2010sensitive glutamate EPSCs, recorded at holding potentials between \u201080 and \u201090 mV, was reversibly reduced by 56 +\/\u2010 11% (n = 6) by dopamine (30 microM). The selective dopamine D1 receptor agonists SKF 38393 (10 microM) and SKF 81297A (10 microM), but not the selective D2 receptor agonist quinpirole (10 microM), also reversibly depressed the EPSC by 36\u201048%. The depression of the EPSC by dopamine was completely blocked by the D1 receptor antagonist SCH 23390 (1 microM), whereas the D2 antagonist (\u2010)\u2010sulpiride (1 microM) was without effect. 2. EPSCs were reversibly depressed by the dopamine mimetic psychostimulants cocaine (1\u201020 microM) and amphetamine (10\u201030 microM) by 40 +\/\u2010 16 and 62 +\/\u2010 9%, respectively, but only in about half of the cells tested (11\/23 and 6\/13, respectively). Their actions were completely reversed by SCH 23390 (1 microM), indicating that endogenous dopamine can also depress the EPSC via D1 receptors. 3. No discernable effects of dopamine, SKF 81297A, SKF 38393, quinpirole, cocaine or amphetamine were observed on membrane conductance or holding current (at holding potentials of \u201080 to \u201090 mV), suggesting that the depression of the EPSC was solely due to an action on presynaptic D1 receptors. 4. In contrast, agents that elevate intracellular levels of adenosine\u20103':5'\u2010cyclic monophosphate (cAMP) (forskolin (1\u201010 microM), 3\u2010isobutyl\u20101\u2010methylxanthine (0.1\u20101 mM), rolipram (10 microM), and dibutyryl cAMP (0.5\u20101 mM)) caused a reversible increase in the EPSC amplitude (by 21\u2010150%). Furthermore, in the presence of forskolin (10 microM), the ability of dopamine to depress synaptic transmission was unaffected. 5. Together these data suggest that both exogenous dopamine and dopamine released from intrinsic nerve terminals attenuate glutamate receptor\u2010mediated synaptic transmission in the nucleus accumbens by presynaptic D1 receptor activation. The transduction mechanism underlying this effect does not appear to involve the formation of cAMP.<\/jats:p>","DOI":"10.1113\/jphysiol.1996.sp021296","type":"journal-article","created":{"date-parts":[[2014,12,17]],"date-time":"2014-12-17T08:24:14Z","timestamp":1418804654000},"page":"143-154","source":"Crossref","is-referenced-by-count":98,"title":["Endogenous and exogenous dopamine depress EPSCs in rat nucleus accumbens in vitro via D1 receptors activation."],"prefix":"10.1113","volume":"492","author":[{"given":"J","family":"Harvey","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M G","family":"Lacey","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[1996,4]]},"container-title":["The Journal of Physiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1113%2Fjphysiol.1996.sp021296","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/physoc.onlinelibrary.wiley.com\/doi\/pdf\/10.1113\/jphysiol.1996.sp021296","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,26]],"date-time":"2023-10-26T18:58:48Z","timestamp":1698346728000},"score":1,"resource":{"primary":{"URL":"https:\/\/physoc.onlinelibrary.wiley.com\/doi\/10.1113\/jphysiol.1996.sp021296"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1996,4]]},"references-count":0,"journal-issue":{"issue":"1","published-print":{"date-parts":[[1996,4]]}},"alternative-id":["10.1113\/jphysiol.1996.sp021296"],"URL":"https:\/\/doi.org\/10.1113\/jphysiol.1996.sp021296","archive":["Portico"],"relation":{},"ISSN":["0022-3751","1469-7793"],"issn-type":[{"value":"0022-3751","type":"print"},{"value":"1469-7793","type":"electronic"}],"subject":[],"published":{"date-parts":[[1996,4]]}}}
