Aversive prediction error signals in the amygdala.
Prediction error signals are fundamental to learning. Here, in mice, we show that aversive prediction signals are found in the hemodynamic responses and theta oscillations recorded from the basolateral amygdala. During fear conditioning, amygdala responses evoked by footshock progressively decreased, whereas responses evoked by the auditory cue that predicted footshock concomitantly increased. ...
متن کاملStress increases aversive prediction error signal in the ventral striatum.
From job interviews to the heat of battle, it is evident that people think and learn differently when stressed. In fact, learning under stress may have long-term consequences; stress facilitates aversive conditioning and associations learned during extreme stress may result in debilitating emotional responses in posttraumatic stress disorder. The mechanisms underpinning such stress-related asso...
متن کاملReward Prediction Error Signals are Metarepresentational
Although there has been considerable debate about the existence of metarepresentational capacities in non-human animals and their scope in humans, the well-confirmed temporal difference reinforcement learning models of rewardguided decision making have been largely overlooked. This paper argues that the reward prediction error signals which are postulated by temporal difference models and have ...
متن کاملWhat the amygdala does and doesn't do in aversive learning.
Whether you are a rat or a rabbit or a mouse or a monkey, your brain is constantly learning. Indeed, one could argue that this is one of the primary purposes of the nervous system: to adapt behavior to changing environments by storing a record of experience. When experiences are aversive, the type of learning that encodes memories of such events is generally called ‘aversive learning.’ And alth...
متن کاملThe feedback-related negativity reflects “more or less” prediction error in appetitive and aversive conditions
Humans make predictions and use feedback to update their subsequent predictions. The feedback-related negativity (FRN) has been found to be sensitive to negative feedback as well as negative prediction error, such that the FRN is larger for outcomes that are worse than expected. The present study examined prediction errors in both appetitive and aversive conditions. We found that the FRN was mo...
