In experiment 1, rats were trained to perform an action sequence until stable performance was achieved, and then, in phase 2, they were switched to perform the reverse sequence. In experiment 2, rats were trained to perform an action sequence, and in phase 2, they continued to do the same sequence. In both experiments in the first 3 days of phase 2, rats were injected with an NK1 receptor antagonist (L-733,060, i.p.) or with vehicle. Additionally, we developed a reinforcement learning model which allowed the in silico replication of our experimental tasks.We found that administering an NK1 receptor antagonist weakened the stable retention of a well-learned sequence, allowing the faster acquisition of a new sequence, without impairing the continued performance of a crystallized sequence. Using our reinforcement learning model, we suggest that SP could be acting through the state value learning rate, modulating the effects of the reward prediction error.Our results suggest that SP could be involved in the consolidation of a sequence representation through a modulatory effect on the reward prediction error. 000258691 536__ $$0G:(DE-HGF)POF4-351$$a351 - Brain Function (POF4-351)$$cPOF4-351$$fPOF IV$$x0 000258691 588__ $$aDataset connected to CrossRef, PubMed, , Journals: pub.dzne.de 000258691 650_2 $$2MeSH$$aRats 000258691 650_2 $$2MeSH$$aAnimals 000258691 650_2 $$2MeSH$$aLearning 000258691 650_2 $$2MeSH$$aReinforcement, Psychology 000258691 650_2 $$2MeSH$$aPiperidines: pharmacology 000258691 650_2 $$2MeSH$$aConditioning, Operant 000258691 650_2 $$2MeSH$$aReward 000258691 650_2 $$2MeSH$$aSubstance P: pharmacology 000258691 650_2 $$2MeSH$$aReceptors, Neurokinin-1 000258691 650_7 $$0148700-85-0$$2NLM Chemicals$$a3-((3,5-bis(trifluoromethyl)phenyl)methyloxy)-2-phenylpiperidine 000258691 650_7 $$2Other$$aAction sequences 000258691 650_7 $$2Other$$areinforcement learning 000258691 650_7 $$2Other$$areward prediction error 000258691 650_7 $$2Other$$astriosomes 000258691 650_7 $$2Other$$asubstance P 000258691 650_7 $$2NLM Chemicals$$aPiperidines 000258691 650_7 $$033507-63-0$$2NLM Chemicals$$aSubstance P 000258691 650_7 $$2NLM Chemicals$$aReceptors, Neurokinin-1 000258691 7001_ $$aGurney, Kevin$$b1 000258691 7001_ $$aOverton, Paul G$$b2 000258691 773__ $$0PERI:(DE-600)2028926-1$$a10.1177/02698811231161582$$gp. 026988112311615 -$$n6$$p610-626$$tJournal of psychopharmacology$$v37$$x0269-8811$$y2023 000258691 8564_ $$uhttps://journals.sagepub.com/doi/10.1177/02698811231161582 000258691 8564_ $$uhttps://pub.dzne.de/record/258691/files/DZNE-2023-00664.pdf$$yOpenAccess 000258691 8564_ $$uhttps://pub.dzne.de/record/258691/files/DZNE-2023-00664.pdf?subformat=pdfa$$xpdfa$$yOpenAccess 000258691 909CO $$ooai:pub.dzne.de:258691$$pdnbdelivery$$pdriver$$pVDB$$popen_access$$popenaire 000258691 9101_ $$0I:(DE-588)1065079516$$6P:(DE-2719)9001992$$aDeutsches Zentrum für Neurodegenerative Erkrankungen$$b0$$kDZNE 000258691 9131_ $$0G:(DE-HGF)POF4-351$$1G:(DE-HGF)POF4-350$$2G:(DE-HGF)POF4-300$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$aDE-HGF$$bGesundheit$$lNeurodegenerative Diseases$$vBrain Function$$x0 000258691 9141_ $$y2023 000258691 915__ $$0StatID:(DE-HGF)0160$$2StatID$$aDBCoverage$$bEssential Science Indicators$$d2022-11-19 000258691 915__ $$0StatID:(DE-HGF)1190$$2StatID$$aDBCoverage$$bBiological Abstracts$$d2022-11-19 000258691 915__ $$0StatID:(DE-HGF)0113$$2StatID$$aWoS$$bScience Citation Index Expanded$$d2022-11-19 000258691 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000258691 915__ $$0LIC:(DE-HGF)CCBY4$$2HGFVOC$$aCreative Commons Attribution CC BY 4.0 000258691 915__ $$0StatID:(DE-HGF)0430$$2StatID$$aNational-Konsortium$$d2023-10-24$$wger 000258691 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bJ PSYCHOPHARMACOL : 2022$$d2023-10-24 000258691 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS$$d2023-10-24 000258691 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline$$d2023-10-24 000258691 915__ $$0StatID:(DE-HGF)0600$$2StatID$$aDBCoverage$$bEbsco Academic Search$$d2023-10-24 000258691 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bASC$$d2023-10-24 000258691 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List$$d2023-10-24 000258691 915__ $$0StatID:(DE-HGF)1050$$2StatID$$aDBCoverage$$bBIOSIS Previews$$d2023-10-24 000258691 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection$$d2023-10-24 000258691 915__ $$0StatID:(DE-HGF)1030$$2StatID$$aDBCoverage$$bCurrent Contents - Life Sciences$$d2023-10-24 000258691 915__ $$0StatID:(DE-HGF)9900$$2StatID$$aIF < 5$$d2023-10-24 000258691 9201_ $$0I:(DE-2719)5000059$$kAG Krabbe ; AG Krabbe$$lFunctional Diversity of Neural Circuits$$x0 000258691 980__ $$ajournal 000258691 980__ $$aVDB 000258691 980__ $$aUNRESTRICTED 000258691 980__ $$aI:(DE-2719)5000059 000258691 9801_ $$aFullTexts
