    • openAccess   Dopamine, behavioral economics, and effort 

      Salamone, John; Correa, Merce; Farrar, Andrew M.; Nunes, Eric J.; Pardo Andrés, Marta 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 ...

    • closedAccess   Dopamine/adenosine interactions involved in effort-related aspects of food motivation 

      Salamone, John; Correa, Merce 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 ...

    • openAccess   Intra-accumbens injections of the adenosine A(2A) agonist CGS 21680 affect effort-related choice behavior in rats 

      Stopper, Colin M.; Worden, Lila T.; Mingote, Susana; Port, Russell G.; Salamone, John; Font Hurtado, Laura; Pereira, Mariana; Farrar, Andrew M. 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 ...

    • openAccess   Nucleus Accumbens Adenosine A2A Receptors Regulate Exertion of Effort by Acting on the Ventral Striatopallidal Pathway 

      Font Hurtado, Laura; Mingote, Susana; Farrar, Andrew M.; Vontell, Regina; Worden, Lila T.; Stopper, Colin M.; Port, Russell G.; Sink, Kelly S.; Bunce, Jamie G.; Chrobak, James; Salamone, John 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 ...
