Utilizing average reward temporal difference reinforcement learning, we incorporate the elevation of basal reward threshold after long-term drug exposure into the model of drug addiction proposed by Redish. Our model is consistent with the animal models of drug seeking under punishment. In the case of nondrug reward, the model explains increased impulsivity after long-term drug exposure. Furthermore, the existence of a blocking effect for cocaine is predicted by our model. <\/jats:p>","DOI":"10.1162\/neco.2009.10-08-882","type":"journal-article","created":{"date-parts":[[2009,7,27]],"date-time":"2009-07-27T20:17:41Z","timestamp":1248725861000},"page":"2869-2893","source":"Crossref","is-referenced-by-count":38,"title":["A Neurocomputational Model for Cocaine Addiction"],"prefix":"10.1162","volume":"21","author":[{"given":"Amir","family":"Dezfouli","sequence":"first","affiliation":[{"name":"Control and Intelligent Processing Center of Excellence, School of Electrical and Computer Engineering, University of Tehran, Tehran, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Payam","family":"Piray","sequence":"additional","affiliation":[{"name":"Control and Intelligent Processing Center of Excellence, School of Electrical and Computer Engineering, University of Tehran, Tehran, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohammad Mahdi","family":"Keramati","sequence":"additional","affiliation":[{"name":"School of Management and Economics, Sharif University of Technology, Tehran, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hamed","family":"Ekhtiari","sequence":"additional","affiliation":[{"name":"Neurocognitive Laboratory, Iranian National Center for Addiction Studies, Tehran, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Caro","family":"Lucas","sequence":"additional","affiliation":[{"name":"Control and Intelligent Processing Center of Excellence, School of Electrical and Computer Engineering, University of Tehran, Tehran, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Azarakhsh","family":"Mokri","sequence":"additional","affiliation":[{"name":"Department of Psychiatry, Tehran University of Medical Sciences, Tehran, and Department of Clinical Sciences, Iranian National Center for Addiction Studies, Tehran, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"281","reference":[{"key":"B1","doi-asserted-by":"publisher","DOI":"10.1126\/science.1107071"},{"key":"B2","doi-asserted-by":"publisher","DOI":"10.1126\/science.282.5387.298"},{"key":"B3","doi-asserted-by":"publisher","DOI":"10.1007\/s002130051121"},{"key":"B4","doi-asserted-by":"publisher","DOI":"10.1007\/s00213-005-2180-z"},{"key":"B5","volume-title":"Diagnostic and statistical manual of mental disorders","year":"2000"},{"key":"B6","doi-asserted-by":"publisher","DOI":"10.1523\/JNEUROSCI.2225-08.2008"},{"key":"B7","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.0600905103"},{"key":"B8","doi-asserted-by":"publisher","DOI":"10.1037\/10500-002"},{"key":"B9","doi-asserted-by":"publisher","DOI":"10.1287\/mnsc.45.4.560"},{"key":"B10","volume-title":"Reinforcement learning models of the dopamine system and their behavioral implications","author":"Daw N.
