Anatomical dissociation of intracerebral signals for reward and punishment prediction errors in humans
(2021)
Whether maximizing rewards and minimizing punishments rely on distinct brain systems remains debated, given inconsistent results coming from human neuroimaging and animal electrophysiology studies. Bridging the gap across ...
Food tissues as reward for birds
(Sociedad Argentina de Botánica, 2002-12)
Nectar is the reward regularly offered by flowers to their pollinating birds. Studies on pollinalion by birds have focused on nectar as a reward while alternative reward systems have been poorly studied. Previous reviews ...
Expectation of reward differentially modulates executive inhibition
Background: Inhibitory control, a key modulatory component of cognition guiding strategy and behaviour, can be affected by diverse contingencies. We explore here the effect of expectation of reward over behavioural adjustment ...
Sweet taste and nutrient value subdivide rewarding dopaminergic neurons in drosophila
(Cell Press, 2015-03)
Dopaminergic neurons provide reward learning signals in mammals and insects [1-4]. Recent work in Drosophila has demonstrated that water-reinforcing dopaminergic neurons are different to those for nutritious sugars [5]. ...
The Role of Ghrelin in Reward-Based Eating
(Elsevier Science Inc, 2012-09)
The peptide hormone ghrelin acts in the central nervous system as a potent orexigenic signal. Not only is ghrelin recognized as playing an important role in feeding circuits traditionally thought of as affecting body weight ...
A NEUROECONOMIC MODELING OF ATTENTION-DEFICIT/HYPERACTIVITY DISORDER (ADHD)
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2009)
In this paper we present a new neuroeconomics model for decision-making applied to the Attention-Deficit/Hyperactivity Disorder (ADHD). The model is based on the hypothesis that decision-making is dependent on the evaluation ...
Neural markers of social and monetary rewards in children with attention-deficit/hyperactivity disorder and autism spectrum disorder.
Recent theories of decision making propose a shared value-related brain mechanism for encoding monetary and social rewards. We tested this model in children with Attention-Deficit/Hyperactivity Disorder (ADHD), children ...
