“…For example, extremely salty solutions are typically avoided, but physiological salt deprivation will produce approach behavior for salty reinforcers (Robinson and Berridge 2013). Also, cues that predict punishing reinforcers are also sometimes chosen over cues that predict the absence of any reinforcer (Barberini et al 2012). It is not known how the BLA responds in these surprising situations.…”

“…The BLA is thought to encode the association of predictive stimuli with both aversive and appetitive outcomes (Morrison and Salzman 2010;Barberini et al 2012). Reward and punishment are reinforcers of opposite valence (positive versus negative), and these reinforcers typically lead to opposing behaviors (approach versus avoidance).…”

Reward and punishment are often thought of as opposing processes: rewards and the environmental cues that predict them elicit approach and consummatory behaviors, while punishments drive aversion and avoidance behaviors. This framework suggests that there may be segregated brain circuits for these valenced behaviors. The basolateral amygdala (BLA) is one brain region that contributes to both types of motivated behavior. Individual neurons in the BLA can favor positive over negative valence, or vice versa, but these neurons are intermingled, showing no anatomical segregation. The amygdala receives inputs from many brain areas and current theories posit that encoding of positive versus negative valence by BLA neurons is determined by the wiring of each neuron. Specifically, many projections from other brain areas that respond to positive and negative valence stimuli and predictive cues project strongly to the BLA and likely contribute to valence processing within the BLA. Here we review three of these areas, the basal forebrain, the dorsal raphe nucleus and the ventral tegmental area, and discuss how these may promote encoding of positive and negative valence within the BLA.The basic desire to seek reward and avoid punishment shapes virtually all of behavior, and the ability to discriminate between "good" and "bad" environmental cues is critical for guiding choices and maximizing survival. Thus, understanding the brain circuits that encode motivated behaviors is important because it contributes to our knowledge of how we learn, and it is also essential for understanding human disorders associated with abnormal processing of reward and danger (i.e., emotional disorders), such as anxiety, depression, addiction, and post-traumatic stress disorder (PTSD).The amygdala is one brain area implicated in motivated behaviors and the basolateral complex of the amygdala (BLA) receives information about diverse environmental stimuli from many brain regions. The BLA is thought to encode the association of predictive stimuli with both aversive and appetitive outcomes (Morrison and Salzman 2010;Barberini et al. 2012). Reward and punishment are reinforcers of opposite valence (positive versus negative), and these reinforcers typically lead to opposing behaviors (approach versus avoidance). Many theories have suggested that appetitive and aversive systems act in opponent fashion (Solomon and Corbit 1974;Daw et al. 2002). However, it is unclear how the BLA contributes to this. We do not yet understand the extent to which aversive and appetitive information is processed in parallel BLA circuits, or whether individual BLA neurons are involved in the regulation of both types of motivated behaviors.In this review, we propose several models by which functional segregation of valence can be achieved in the BLA. These models are based on studies describing how BLA neurons respond to reward and aversive stimuli. We then consider whether three major inputs, known to carry valenced information, support or conflict these models, and also discus...

“…Based on their findings of gambling task Cauffman et al propose steady increased sensitivity to rewards from late childhood to adolescence that subsequently declines from late adolescence to adulthood [35]. Punishment based decision making on the other hand is based on one or more prior experiences with an aversive outcome [36]. Hence, the sensitivity to punishment is likely to be more in late adulthood and elderly.…”
