Activational and effort-related aspects of motivation: neural mechanisms and implications for psychopathology
Oxford University Press (2016-04-26)Motivation has been defined as the process that allows organisms to regulate their internal and external environment, and control the probability, proximity and availability of stimuli. As such, motivation is a complex ... -
Actualización de la subescala SR del SPSRQ y análisis de las propiedades psicométricas del nuevo instrumento
Universitat Jaume I (2017)La Teoría de la Sensibilidad al Refuerzo de Gray (RST) (1981,1982, 1987), establece tres susbsistemas neurobiológicos que actúan para regular la conducta. Torrubia, Ávila, Moltó y Caseras (2001) desarrollaron el Cuestionario ... -
Complexities and paradoxes in understanding the role of dopamine in incentive motivation and instrumental action: Exertion of effort vs. anhedonia
Elsevier (2022-05)Instrumental behavior is a very complex and multifaceted process. Behavioral output during instrumental performance is influenced by a variety of factors, including associative conditioning, directional and activational ... -
Diferencias anatómicas asociadas a la sensibilidad al castigo y a la recompensa: un estudio de morfometría basada en el vóxel
Universitat Jaume I (2017)Introducción: La teoría de la sensibilidad al refuerzo (tsr) propone el sistema de activación conductual (sac) como el sistema motivacional encargado de dirigir la con- ducta hacia la obtención de estímulos apetitivos. ... -
Dopamine and Food Addiction: Lexicon Badly Needed
Elsevier (2013-05-01)Over the last few years, the concept of food addiction has become a common feature in the scientific literature, as well as the popular press. Nevertheless, the use of the term addiction to describe pathological aspects ... -
Evolution of vertebrate survival circuits
Elsevier (2018-12)Evolution selects those adaptive features that increase reproductive probabilities and facilitate survival. Analysing the brain circuits mediating risk-avoidance (e.g. defense) and those allowing reward-seeking (motivated) ... -
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. ... -
Influencia de la recompensa y las diferencias individuales en Sensibilidad a la Recompensa sobre la interferencia cognitiva
Universitat Jaume I (2014-07-22)El objetivo de este estudio es conocer si la recompensa produce una mejora en el control ejecutivo y ver en qué medida se produce esta mejora en función del grado de recompensa. Asimismo, se pretende ver cómo la ... -
Insulin and Ventral Tegmental Dopamine: What's Impaired and What's Intact?
Elsevier (2013-04-02)Manipulations affecting mesolimbic dopamine transmission exert specific effects on normal and pathological aspects of motivation, altering some functions while sparing others. Labouèbe et al. (2013) show that insulin induced ... -
Intraspecific Communication Through Chemical Signals in Female Mice: Reinforcing Properties of Involatile Male Sexual Pheromones
Oxford University Press (2007)In rodents, social and reproductive behaviors critically depend on chemical signals, including sexual pheromones that have been suggested (but not demonstrated) to be rewarding. In this work, we analyze this issue by ... -
Las diferencias individuales en sensibilidad a la recompensa modulan la actividad cerebral en una tarea de control inhibitorio con contingencias de reforzamiento
Universitat Jaume I (2015)Introducción: La motivación apetitiva influye sobre procesos cognitivos como el control inhibitorio, y dicha influencia parece asociarse con cambios en la actividad del sistema dopaminérgico. Por otra parte, las diferencias ... -
Low-Affinity/High-Selectivity Dopamine Transport Inhibition Sufficient to Rescue Cognitive Functions in the Aging Rat
MDPI (2023-03)The worldwide increase in cognitive decline, both in aging and with psychiatric disorders, warrants a search for pharmacological treatment. Although dopaminergic treatment approaches represent a major step forward, current ... -
Nucleus accumbens and effort-related functions: behavioral and neural markers of the interactions between adenosine A2A and dopamine D2 receptors
Elsevier (2010-04)Nucleus accumbens dopamine (DA) is a critical component of the brain circuitry regulating work output in reinforcement-seeking behavior and effort-related choice behavior. Moreover, there is evidence of an interaction ... -
Relevance of the anterior cingulate cortex volume and personality in motivated physical activity behaviors
Springer Nature (2023-10-31)Some recent theories about the origins and maintenance of regular physical activity focus on the rewards of the properties of practicing this activity. Animal and human studies have demonstrated that mesolimbic dopamine ... -
Reward network connectivity “at rest” is associated with reward sensitivity in healthy adults: A resting-state fMRI study
Springer (2019)The behavioral approach system (BAS), based on reinforcement sensitivity theory (RST), is a neurobehavioral system responsible for detecting and promoting motivated behaviors towards appetitive stimuli. Anatomically, the ... -
Role of AMPA glutamate receptors in the conditioned rewarding effects of MDMA in mice
Elsevier (2018-07-16)Currently, there is not an effective treatment for 3,4-methylenedioxymethamphetamine (MDMA) dependence but pharmacotherapies targeting glutamate neurotransmission are a promising strategy. Previously, we showed that blockade ... -
Role of the vomeronasal system in intersexual attraction in female mice
Elsevier (2008-05)Although it is generally accepted that rodents' sociosexual behavior relies mainly on chemosignals, the specific roles played by the vomeronasal and olfactory systems in detecting these signals are presently unclear. This ...
