Journal ArticleDOI
Interplay of approximate planning strategies
Quentin J. M. Huys,Quentin J. M. Huys,Níall Lally,Níall Lally,Paul Faulkner,Neir Eshel,Erich Seifritz,Samuel J. Gershman,Peter Dayan,Jonathan P. Roiser +9 more
TL;DR: Model-based behavioral analysis is used to provide a detailed examination of the performance of human subjects in a moderately deep planning task and finds that subjects exploit the structure of the domain to establish subgoals in a way that achieves a nearly maximal reduction in the cost of computing values of choices.
Journal ArticleDOI
Losing the rose tinted glasses: Neural substrates of unbiased belief updating in depression
Neil Garrett,Tali Sharot,Paul Faulkner,Christoph W. Korn,Jonathan P. Roiser,Raymond J. Dolan +5 more
TL;DR: Brain imaging is used in conjunction with a belief update task administered to clinically depressed patients and healthy controls to characterize brain activity that supports unbiased belief updating in clinically depressed individuals.
Journal ArticleDOI
The role of serotonin in reward, punishment and behavioural inhibition in humans: insights from studies with acute tryptophan depletion.
Paul Faulkner,J F William Deakin +1 more
TL;DR: Two of these studies strongly indicate that ATD blocks 5-HT mediated aversively conditioned Pavlovian inhibition and this can explain a number of the behavioural effects of ATD.
Journal ArticleDOI
Measuring endogenous changes in serotonergic neurotransmission in humans: a [11C]CUMI-101 PET challenge study.
Sudhakar Selvaraj,Sudhakar Selvaraj,Federico Turkheimer,Lula Rosso,Paul Faulkner,Elias Mouchlianitis,J. P. Roiser,Philip McGuire,Philip J. Cowen,Oliver D. Howes,Oliver D. Howes +10 more
TL;DR: It is concluded that [11C]CUMI-101 may be sensitive to changes in endogenous 5-HT release in humans, consistent with preclinical animal studies, in which acute administration of SSRIs decreases DRN cell firing through activation of5-HT1A autoreceptors to reduce 5- HT levels in postsynaptic regions.
Journal ArticleDOI
Sex differences in tobacco withdrawal and responses to smoking reduced-nicotine cigarettes in young smokers
Paul Faulkner,Nicole Petersen,Dara G. Ghahremani,Chelsea M. Cox,Rachel F. Tyndale,Rachel F. Tyndale,Gerhard Hellemann,Edythe D. London +7 more
TL;DR: Men may experience less smoking-related relief of craving, and enjoy cigarettes less, if nicotine yields are reduced to very low levels, while women respond equally well to cigarettes with nicotine yields as low as 0.027 mg; these differences are relevant for policy regarding reduced nicotine in cigarettes.
