Humans and animals realize cost/benefits analysis of our responses with the goal of use the lowest
energy possible to obtain the major benefit. Mesolimbic dopamine (DA) is a critic component in
the cerebral circuitry regulating decision making based on the effort that the response requires,
because it regulates behavioral activation. Research with rodents show that DA antagonists displace
the behavior from the response that supposes more effort, though it has more reinforcement, to other
behavior with less effort required. Interaction between A2A adenosine receptors and D2 receptors
play an essential paper in these processes. In the T-Maze paradigm the animal is exposed to an
option of choose one arm with two food pellets, to which it accedes after climbing a 14 cm barrier,
or to choose the arm without barrier and with only one food pellet. Control animals choose to do the
effort of climbing the barrier to obtain the high reinforcement. Haloperidol, D2 antagonist, produces
change behavior towards the less density arm, been this effect partially reverted with theophylline,
unspecific adenosine antagonist, and with MSX-3, selective A2A antagonist. These drugs could have
applications for the treatment of amotivational syndromes. [-]
