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 ... -
Effects of the dopamine depleting agent tetrabenazine in tests evaluating different components of depressive-like behavior in mice : sex-dependent response to antidepressant drugs with SERT and DAT blocker profiles
Springer Nature (2023-07-05)Background ; Depression is a disorder twice as common in women than in men. There are sex differences in the symptomatology and treatment response to this disorder. Impairments in behavioral activation (i.e. anergia, ... -
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 ... -
Energizing effects of bupropion on effortful behaviors in mice under positive and negative test conditions: modulation of DARPP-32 phosphorylation patterns
Springer (2021-09-09)Motivational symptoms such as anergia, fatigue, and reduced exertion of effort are seen in depressed people. To model this, nucleus accumbens (Nacb) dopamine (DA) depletions are used to induce a low-effort bias in rodents ... -
Engaged, Workaholic, Burned-Out or Just 9-to-5? Toward a Typology of Employee Well-being
Wiley (2013-05)The aim of this study was to establish a typology of employee well-being, together with its psychosocial antecedents and consequences. Results obtained with a sample of 786 full-time employees from different occupational ... -
Forebrain circuitry involved in effort-related choice: Injections of the GABAA agonist muscimol into ventral pallidum alter response allocation in food-seeking behavior
Elsevier (2008-03)Organisms often make effort-related choices based upon assessments of motivational value and work requirements. Nucleus accumbens dopamine is a critical component of the brain circuitry regulating work output in ... -
High versus low motivating music on intermittent fitness and agility in young well-trained basketball players
Routledge (2021-03-31)The present study aimed to analyse the influence of the music level of motivation, compared to the absence of music, on intermittent fitness and agility, in a group of young well-trained basketball players. On alternate ... -
Multiple Sclerosis and Depression: Translation and Adaptation of the Spanish Version of the Chicago Multiscale Depression Inventory and the Study of Factors Associated with Depressive Symptoms
Oxford University Press (2022-12-08)Objective: Depressive disorder occurs in up to 50% of persons with Multiple Sclerosis (PwMS). Accurate assessment of depression in MS is essential in clinical settings because depressive symptomatology can affect the ... -
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 ... -
Regional Brain Atrophy and Functional Connectivity Changes Related to Fatigue in Multiple Sclerosis
Public Library of Science (2013)Fatigue is one of the most frequent symptoms in multiple sclerosis (MS), and recent studies have described a relationship between the sensorimotor cortex and its afferent and efferent pathways as a substrate of fatigue. ... -
Sex differences in lever pressing and running wheel tasks of effort-based choice behavior in rats: Suppression of high effort activity by the serotonin transport inhibitor fluoxetine
Elsevier (2021)Selective serotonin transport (SERT) inhibitors such as fluoxetine are the most commonly prescribed treatments for depression. Although efficacious for many symptoms of depression, motivational impairments such as psychomotor ... -
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 ... -
The week after running a marathon: effects of running vs elliptical Training vs resting on neuromuscular performance and muscle damage recovery
Taylor & Francis & European College of Sport Science (2021-01-18)Our aim was to compare the effects of two exercise modalities vs resting on the time course of neuromuscular performance and muscle damage recovery during the week after running a marathon. Sixty-four finishers from a road ...
