- The µ-opioid system promotes visual attention to faces and eyesOlga Chelnokova
Department of Psychology, University of Oslo, Oslo N 0317, Norway
Soc Cogn Affect Neurosci 11:1902-1909. 2016..Enhanced attention to others' faces and eyes represents a putative behavioral mechanism through which the human MOR system promotes social interest...
- Oxytocin enhances pupil dilation and sensitivity to 'hidden' emotional expressionsSiri Leknes
Department of Psychology, University of Oslo, Postboks 1094, Blindern 0317, Oslo, Norway
Soc Cogn Affect Neurosci 8:741-9. 2013..Since pupil dilation can be associated with increased attractiveness and approach behaviour, this effect could also represent a mechanism by which oxytocin increases human affiliation. ..

Centre for Functional Magnetic Resonance Imaging of the Brain, Nuffield Department of Clinical Neurosciences Nuffield Division of Anaesthetics, University of Oxford, Oxford, UK
Pain 154:402-10. 2013..The findings of this study point to a role for brainstem and reward circuitry in a context-induced "hedonic flip" of pain...
- Pain relief as an opponent process: a psychophysical investigationSiri Leknes
Oxford Centre for Functional MRI of the Brain, Clinical Neurology and Nuffield Department of Anaesthetics, Oxford University, John Radcliffe Hospital, Oxford, UK

- Relief as a reward: hedonic and neural responses to safety from painSiri Leknes
Nuffield Division of Anaesthetics, Nuffield Department of Clinical Neurosciences, Centre for Functional Magnetic Resonance Imaging of the Brain FMRIB, University of Oxford, Oxford, Oxfordshire, United Kingdom
PLoS ONE 6:e17870. 2011..In conclusion, relief differs from appetitive rewards due to its reliance on negative expectations, the violation of which is reflected in relief-related accumbens activation...
- Induction of depressed mood disrupts emotion regulation neurocircuitry and enhances pain unpleasantnessChantal Berna
Centre for Functional Magnetic Resonance Imaging of the Brain, Department of Clinical Neurology, University of Oxford, Oxford, United Kingdom
Biol Psychiatry 67:1083-90. 2010..We hypothesized that dysregulation of the neural circuitry underlying emotion regulation is the mechanism whereby pain processing is affected during depressed mood...

Psychopharmacology (Berl) 233:3711-3723. 2016..Rodent models highlight the key role of μ-opioid receptor (MOR) signaling in palatable food consumption. In humans, however, the effects of MOR stimulation on eating and food liking remain unclear...
