Recent studies have shown that some alterations present in cocaine users may be related to the activity of large functional networks. The aim of this study was to investigate how these functional networks are modulated by non\u2010drug rewarding stimuli in cocaine\u2010dependent individuals. Twenty abstinent cocaine\u2010dependent and 21 healthy matched male controls viewed erotic and neutral pictures while undergoing a functional magnetic resonance imaging scan. Group independent component analysis was then performed in order to investigate how functional networks were modulated by reward in cocaine addicts. The results showed that cocaine addicts, compared with healthy controls, displayed diminished modulation of the left frontoparietal network in response to erotic pictures, specifically when they were unpredicted. Additionally, a positive correlation between the length of cocaine abstinence and the modulation of the left frontoparietal network by unpredicted erotic images was found. In agreement with current addiction models, our results suggest that cocaine addiction contributes to reduce sensitivity to rewarding stimuli and that abstinence may mitigate this effect.<\/jats:p>","DOI":"10.1111\/adb.12329","type":"journal-article","created":{"date-parts":[[2015,11,27]],"date-time":"2015-11-27T08:08:47Z","timestamp":1448611727000},"page":"479-489","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":23,"title":["Reduced activity in functional networks during reward processing is modulated by abstinence in cocaine addicts"],"prefix":"10.1111","volume":"22","author":[{"given":"V\u00edctor","family":"Costumero","sequence":"first","affiliation":[{"name":"Departamento de Psicolog\u00eda B\u00e1sica, Cl\u00ednica y Psicobiolog\u00eda Universitat Jaume I  Castell\u00f3n Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juan Carlos","family":"Bustamante","sequence":"additional","affiliation":[{"name":"Departamento de Psicolog\u00eda y Sociolog\u00eda Universidad de Zaragoza  Zaragoza Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Patricia","family":"Rosell\u2010Negre","sequence":"additional","affiliation":[{"name":"Departamento de Psicolog\u00eda B\u00e1sica, Cl\u00ednica y Psicobiolog\u00eda Universitat Jaume I  Castell\u00f3n Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paola","family":"Fuentes","sequence":"additional","affiliation":[{"name":"Departamento de Psicolog\u00eda B\u00e1sica, Cl\u00ednica y Psicobiolog\u00eda Universitat Jaume I  Castell\u00f3n Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juan Jos\u00e9","family":"Llopis","sequence":"additional","affiliation":[{"name":"Addictive Behaviors Unit San Agust\u00edn  Castell\u00f3n Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C\u00e9sar","family":"\u00c1vila","sequence":"additional","affiliation":[{"name":"Departamento de Psicolog\u00eda B\u00e1sica, Cl\u00ednica y Psicobiolog\u00eda Universitat Jaume I  Castell\u00f3n Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alfonso","family":"Barr\u00f3s\u2010Loscertales","sequence":"additional","affiliation":[{"name":"Departamento de Psicolog\u00eda B\u00e1sica, Cl\u00ednica y Psicobiolog\u00eda Universitat Jaume I  Castell\u00f3n Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2015,11,27]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.3389\/fnsys.2011.00002"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1369-1600.2010.00230.x"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1162\/neco.1995.7.6.1129"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuropharm.2013.02.018"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1038\/npp.2008.135"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.0911855107"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/adb.12041"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1002\/hbm.1048"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1002\/hbm.22436"},{"key":"e_1_2_6_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuron.2008.04.017"},{"key":"e_1_2_6_12_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00429-014-0760-6"},{"key":"e_1_2_6_13_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0066940"},{"key":"e_1_2_6_14_1","doi-asserted-by":"publisher","DOI":"10.1523\/JNEUROSCI.0909-12.2012"},{"key":"e_1_2_6_15_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1369-1600.2008.00129.x"},{"key":"e_1_2_6_16_1","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.0704320104"},{"key":"e_1_2_6_17_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.biopsych.2009.12.013"},{"key":"e_1_2_6_18_1","doi-asserted-by":"publisher","DOI":"10.1176\/appi.ajp.157.11.1789"},{"key":"e_1_2_6_19_1","doi-asserted-by":"publisher","DOI":"10.1177\/0004867413508455"},{"key":"e_1_2_6_20_1","doi-asserted-by":"publisher","DOI":"10.1176\/ajp.2007.164.1.43"},{"key":"e_1_2_6_21_1","doi-asserted-by":"publisher","DOI":"10.1176\/appi.ajp.159.10.1642"},{"key":"e_1_2_6_22_1","doi-asserted-by":"publisher","DOI":"10.1016\/0166-2236(92)90344-8"},{"key":"e_1_2_6_23_1","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.0135058100"},{"key":"e_1_2_6_24_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuroimage.2004.03.027"},{"key":"e_1_2_6_25_1","doi-asserted-by":"publisher","DOI":"10.1038\/npp.2013.314"},{"key":"e_1_2_6_26_1","doi-asserted-by":"publisher","DOI":"10.1002\/hbm.20807"},{"key":"e_1_2_6_27_1","doi-asserted-by":"publisher","DOI":"10.1093\/schbul\/sbn133"},{"key":"e_1_2_6_28_1","unstructured":"LangPJ BradleyMM CuthbertBN(1999)International affective picture system (IAPS): instruction manual and affective ratings.
