Attraction to sexual pheromones and associated odorants in female mice involves activation of the reward system and basolateral amygdala
Wiley (2005-04)Adult female mice are innately attracted to non-volatile pheromones contained in male-soiled bedding. In contrast, male-derived volatiles become attractive if associated with non-volatile attractive pheromones, which act ... -
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 ... -
Effort-related motivational effects of the pro-inflammatory cytokine interleukin 1-beta: studies with the concurrent fixed ratio 5/ chow feeding choice task
Springer (2014-02)Rationale. Effort-related motivational symptoms such as anergia and fatigue are common in patients with depression and other disorders. Research implicates pro-inflammatory cytokines in depression, and administration of ... -
Elegir entre consumir dulces o hacer ejercicio depende de la modulación dopaminérgica en el circuito cerebral que regula la motivación
Universitat Jaume I (2015)Introducción: Los organismos continuamente toman decisiones basadas en el valor de los reforzadores y los costes que suponen las respuestas para conseguirlos. La magnitud del esfuerzo que la conducta a ejecutar requiere, ... -
Impact of Caffeine on Ethanol‐Induced Stimulation and Sensitization: Changes in ERK and DARPP‐32 Phosphorylation in Nucleus Accumbens
Wiley (2021)Background: Caffeine is frequently consumed with ethanol to reduce the impairing effects induced by ethanol, including psychomotor slowing or incoordination. Both drugs modulate dopamine (DA)‐related markers in accumbens ... -
Selective dopaminergic lesions of the ventral tegmental area impair preference for sucrose but not for male sexual pheromones in female mice
Wiley (2006-08)The role of the meso-accumbens dopaminergic pathway in reward-related behaviours is the subject of intense investigation. In this regard, here we analyse the effects of specific lesions of dopaminergic cells of the ventral ... -
The monoamine-oxidase B inhibitor deprenyl increases selection of high-effort activity in rats tested on a progressive ratio/chow feeding choice procedure: Implications for treating motivational dysfunctions
Elsevier (2018-04)Motivated behaviors often are characterized by a high degree of behavioral activation and work output, and organisms frequently make effort-related decisions based upon cost/benefit analyses. Moreover, people with depression ...
