How the brain translates money into force: a neuroimaging study of subliminal motivationMathias Pessiglione
Wellcome Trust Centre for Neuroimaging, Institute of Neurology, University College London, 12 Queen Square London WC1N 3BG, UK
Science 316:904-6. 2007..Our findings thus reveal this region as a key node in brain circuitry that enables expected rewards to energize behavior, without the need for the subjects;awareness...
Subliminal instrumental conditioning demonstrated in the human brainMathias Pessiglione

Neuron 59:561-7. 2008..We conclude that, even without conscious processing of contextual cues, our brain can learn their reward value and use them to provide a bias on decision making...
An effect of dopamine depletion on decision-making: the temporal coupling of deliberation and executionMathias Pessiglione
Hopital de la Salpetriere, Paris, France
J Cogn Neurosci 17:1886-96. 2005..We suggest that such coupling may be related to the loss of dopamine-mediated functional segregation between basal ganglia circuits processing different stages of goal-directed behavior...

Neural mechanisms underlying motivation of mental versus physical effortLiane Schmidt
Motivation, Brain and Behavior MBB Team, Institut du Cerveau et de la Moëlle épinière ICM, Paris, France
PLoS Biol 10:e1001266. 2012..Thus, we suggest that the interaction between a common motivational system and the different task-specific systems underpinning behavioral performance might occur within the basal ganglia...
Splitting motivation: unilateral effects of subliminal incentivesLiane Schmidt
institut du cerveau et de la moelle épinière, Paris, France
Psychol Sci 21:977-83. 2010..These results show that in the absence of conscious control, one brain hemisphere, and hence one side of the body, can be motivated independently of the other...
Disruption of self-organized actions in monkeys with progressive MPTP-induced parkinsonism. I. Effects of task complexityMathias Pessiglione
, , Paris, France
Eur J Neurosci 19:426-36. 2004..We therefore suggest that everyday cognitive difficulties may exacerbate hypokinesia (lack of initiation, abnormal slowness) and executive disorders (hesitations, freezing) in the early stages of human PD...
Similar improvement of reward and punishment learning by serotonin reuptake inhibitors in obsessive-compulsive disorderStefano Palminteri
Institut National de la Santé et de la Recherche Médicale Unité 975, Centre National de la Recherche Scientifique Unité 7225, Groupe Hospitalier Pitie Salpetriere, Universite Pierre et Marie Curie Paris 6, Paris, France
Biol Psychiatry 72:244-50. 2012..An influential theory has suggested that dopamine and serotonin represent opponent systems respectively driving reward and punishment learning...
Reinforcement learning and Gilles de la Tourette syndrome: dissociation of clinical phenotypes and pharmacological treatmentsYulia Worbe
Centre de Recherche de l Institut du Cerveau et de la Moelle Epiniere, Hopital Pitie Salpetriere, Paris, France
Arch Gen Psychiatry 68:1257-66. 2011..The heterogeneity of clinical phenotypes may relate to the dysfunction of distinct frontal cortex-basal ganglia circuits...
Get aroused and be stronger: emotional facilitation of physical effort in the human brainLiane Schmidt
Institut du Cerveau et de la Moëlle épinière ICM, INSERM UMRS 975, Paris, France
J Neurosci 29:9450-7. 2009..We suggest that this region, by driving the motor cortex, constitutes a brain pathway that allows emotional arousal to facilitate physical effort...
Dopamine-dependent reinforcement of motor skill learning: evidence from Gilles de la Tourette syndromeStefano Palminteri
institut du cerveau et de la moelle épinière, Groupe Hospitalier Pitie Salpetriere, Paris, France
Brain 134:2287-301. 2011..These results support the hypothesis that overactive dopamine transmission leads to excessive reinforcement of motor sequences, which might explain the formation of tics in Gilles de la Tourette syndrome...
An automatic valuation system in the human brain: evidence from functional neuroimagingMaël Lebreton
Institut du Cerveau et de la Moëlle èpinière CR ICM, INSERM UMR 975, Paris, France
Neuron 64:431-9. 2009..These regions may therefore constitute a brain system that automatically engages in valuating the various components of our environment so as to influence our future choices...
Learning affective values for faces is expressed in amygdala and fusiform gyrusPredrag Petrovic
Wellcome Trust Centre for Neuroimaging, University College of London, 12 Queen Square, London, WC1N 3BG, UK
Soc Cogn Affect Neurosci 3:109-18. 2008..We conclude that amygdala and fusiform encode affective value in a manner that closely approximates a standard computational solution to learning...

Motivation, Brain and Behavior lab, institut du cerveau et de la moelle épinière, Hopital de la Pitie Salpetriere, Paris, France

, , , 75651 Paris, France
J Neurosci 25:1523-31. 2005..Thus the major dysfunction after dopamine depletion appeared to be the loss of functional segregation within cortico-BG circuits, which could also be at the heart of parkinsonian pathophysiology...
