A cognitive neuroscience approach to individual differences in sensitivity to reward
Springer-Verlag (2008)The Reinforcement Sensitivity Theory proposes that a neurobiological system, the Behavioral Activation System, defines individual differences on the subject’s sensitivity and reactivity to appetitive stimuli associated ... -
A new window to understanding individual differences in reward sensitivity from attentional networks
Springer (2014-04)Existing evidence suggests that the presence of reward cues modifies the activity in attentional networks, however, the nature of these influences remains poorly understood. Here, we performed independent component analysis ... -
Abstinence duration modulates striatal functioning during monetary reward processing in cocaine patients
Wiley (2013)Pre-clinical and clinical studies in cocaine addiction highlight alterations in the striatal dopaminergic reward system that subserve maintenance of cocaine use. Using an instrumental conditioning paradigm with monetary ... -
Acquisition and reconditioning of ethanol-induced conditioned place preference in mice is blocked by the H2O2 scavenger alpha lipoic acid
Springer (2012)Rationale Hydrogen peroxide (H2 O2) is the co-substrate used by catalase to metabolize ethanol to acetaldehyde in the brain. This centrally formed acetaldehyde has been involved in several ethanol-related behaviors. ... -
Choosing voluntary exercise over sucrose consumption depends upon dopamine transmission: effects of haloperidol in wild type and adenosine A2AKO mice
Springer (2016-02)Rationale: Mesolimbic dopamine (DA) regulates behavioral activation and effort-related decision-making in motivated behaviors. Mesolimbic DA D2 receptors are co-localized with adenosine A2A receptors, and they interact in ... -
Differential effects of selective adenosine antagonists on the effort-related impairments induced by dopamine D1 and D2 antagonism
Elsevier (2010)Mesolimbic dopamine (DA) is a critical component of the brain circuitry regulating behavioral activation and effort-related processes. Rats with impaired DA transmission reallocate their instrumental behavior away from ... -
Dopamine, behavioral economics, and effort
Frontiers Research Foundation (2009)There are numerous problems with the hypothesis that brain dopamine (DA) systems, particularly in the nucleus accumbens, directly mediate the rewarding or primary motivational characteristics of natural stimuli such as ... -
Dopamine, Effort-Based Choice, and Behavioral Economics: Basic and Translational Research
Frontiers Media (2018-03)Operant behavior is not only regulated by factors related to the quality or quantity of reinforcement, but also by the work requirements inherent in performing instrumental actions. Moreover, organisms often make ... -
Dopamine/adenosine interactions involved in effort-related aspects of food motivation
Elsevier (2009)Nucleus accumbens dopamine (DA) is involved in effort-related aspects of food motivation. Accumbens DA depletions reduce the tendency of rats to work for food, and alter effort-related choice, but leave other aspects of ... -
Effects of brain insulin in conditioned place preference using exercise as a reward stimulus
Universitat Jaume I (2017-09-21)Researches suggest that physical activity is effective to prevent or treat stress-related psychiatric disorders such as depression, anxiety, and substance abuse disorders. Both, natural and drugs rewards is processed by ... -
Focal Lesions within the ventral striato-pallidum abolish attraction for male chemosignals in female mice
Elsevier (2014-02)In rodents, socio-sexual behaviour is largely mediated by chemosensory cues, some of which are rewarding stimuli. Female mice display an innate attraction towards male chemosignals, dependent on the vomeronasal system. ... -
Glutamate and Opioid Antagonists Modulate Dopamine Levels Evoked by Innately Attractive Male Chemosignals in the Nucleus Accumbens of Female Rats
Frontiers Media (2017-02-23)Sexual chemosignals detected by vomeronasal and olfactory systems mediate intersexual attraction in rodents, and act as a natural reinforcer to them. The mesolimbic pathway processes natural rewards, and the nucleus ... -
Hiperactivación del córtex visual secundario en adictos a cocaína durante una tarea de counting Stroop con contingencias de recompensa
Universitat Jaume I (2015-06-15)Introducción: La motivación apetitiva, en sujetos sanos, mejora el procesamiento cognitivo, aunque hay condiciones que lo empeora. Por otra parte, las personas adictas a cocaína muestran un déficit en las funciones ... -
Juvenile play conditions sexual partner preference in adult female rats
Elsevier (2011)Rats can display a conditioned partner preference for individuals that bear an odor previously associated with sexual reward. Herein we tested the possibility that odors associated with the reward induced by social play in ... -
Naloxone effects on extinction of ethanol- and cocaine-induced conditioned place preference in mice
Springer Verlag (2017)Rationale Previous studies found that naloxone (NLX) facilitated choice extinction of ethanol conditioned place preference (CPP) using long (60 min) test sessions, but there is little information on the variables ... -
Nucleus accumbens neurotransmission and effort-related choice behavior in food motivation: Effects of drugs acting on dopamine, adenosine, and muscarinic acetylcholine receptors
Elsevier (2013)Mesolimbic dopamine (DA) is a critical component of the brain circuitry regulating behavioral activation and effort-related processes. Although nucleus accumbens (NAc) DA depletions or antagonism leave aspects of appetite ... -
Preference for Exercise vs. More Sedentary Reinforcers: Validation of an Animal Model of Tetrabenazine-Induced Anergia
Frontiers Media (2020-01-30)Physical activities can have intrinsic motivational or reinforcing properties. The choice to engage in voluntary physical activity is undertaken in relation to the selection of other alternatives, such as sedentary ... -

Reward anticipation enhances brain activation during response inhibition
Springer (2014-06)The chance to achieve a reward starts up the required neurobehavioral mechanisms to adapt our thoughts and actions in order to accomplish our objective. However, reward does not equally reinforce everybody but depends on ... -
The VMAT-2 inhibitor tetrabenazine alters effort-related decision making as measured by the T-maze barrier choice task: reversal with the adenosine A2A antagonist MSX-3 and the catecholamine uptake blocker bupropion
Springer Verlag (2015)Rationale Depressed people show effort-related motivational symptoms, such as anergia, retardation, lassitude, and fatigue. Animal tests can model these motivational symptoms, and the present studies characterized the ...
