Bases biológicas del consumo compulsivo del azúcar
Universitat Jaume I (2017)En la actualidad, los trastornos de conducta alimentaria están recibiendo una notoria atención, pues cada vez son más frecuentes y aparecen en edades más tempranas. Este consumo disparatado de grasas y azúcar está ... -
Behavioral manipulations for the improvement of anergia: impact on the mesolimbic dopaminergic system
Universitat Jaume I (2016-07-20)Studies with animals have shown that exercise can have neuroprotective effects which has led to suggestions that physical exercise could have positive effects in the prevention/treatment of various neurologic or psychiatric ... -
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 ... -
Efavirenz induces anergia in animal models for the study of the activational deficits observed in depression : therapeutic effect of the chatecolamine uptake inhibitor bupropion
Universitat Jaume I (2016-07-18)A high degree of behavioral activation and work output are observed in motivated behaviors. Mesolimbic DA plays an important role in the regulation of this activational component of motivation. Anergia and fatigue are ... -
Efectos del metilfenidato sobre la ansiedad
(2013-04-15)The attention deficit disorder with hyperactivity (ADDH) is a widely recognized disorder of unknown etiology. Methylphenidate administration is one of the most commonly used treatments to improve symptoms associated with ... -
Evidencia conductual y neurobiológica del potencial adictivo del azúcar
Universitat Jaume I (2017-07-17)The massive use of sugar in the food industry, and the high rates of obesity documented by the WHO, have fueled the investigation of the addictive properties of this substance. In the present manuscript we review evidence ... -
Impacto del ejercicio físico sobre los sistemas dopaminérgicos: relevancia para la elección de reforzadores activos y la prevención de la anergia en modelos animales.
Universitat Jaume I (2015-06-15)Introduction Sedentary Modern lifestyles are associated with an increased risk of pathologies such as obesity, cardiovascular diseases or depression, while physical activity has demonstrated to improve brain health and ... -
Intra-accumbens injections of the adenosine A(2A) agonist CGS 21680 affect effort-related choice behavior in rats
Springer Verlag (2008)Rationale: Nucleus accumbens dopamine (DA) participates in the modulation of instrumental behavior, including aspects of behavioral activation and effort-related choice behavior. Rats with impaired accumbens DA transmission ... -
Nucleus Accumbens Adenosine A2A Receptors Regulate Exertion of Effort by Acting on the Ventral Striatopallidal Pathway
Society for Neuroscience (2008)Goal-directed actions are sensitive to work-related response costs, and dopamine in nucleus accumbens is thought to modulate the exertion of effort in motivated behavior. Dopamine-rich striatal areas such as nucleus ... -
Papel terapéutico del ejercicio físico en los síntomas motores de la enfermedad de Párkinson
Universitat Jaume I (2014)La enfermedad de Párkinson es el segundo trastorno neurodegenerativo más frecuente en el mundo que se caracteriza principalmente por una serie de síntomas motores. Actualmente no existe cura y se están investigando ... -
Role of dopamine–adenosine interactions in the brain circuitry regulating effort-related decision making: insights into pathological aspects of motivation
Future Medicine (2010)Brain dopamine, particularly in the nucleus accumbens, has been implicated in activational aspects of motivation and effort-related processes. Accumbens dopamine depletions reduce the tendency of rats to work for food, and ... -
Salsolinol, posible mediador de los efectos del etanol en organismos
Universitat Jaume I (2017)El alcohol es la droga más aceptada y consumida en el mundo, la cual puede causarte un alto nivel de dependencia, a causa, principalmente, del efecto reforzante que produce en tu cerebro. En el presente trabajo nos vamos ...
