Site summary — not the original abstract
Wenzel and colleagues reviewed neurochemical evidence that dopamine in the nucleus accumbens participates in responses to aversive as well as rewarding events; the reviewed findings vary with brain subregion, measurement timescale, stimulus, and behavioral task. [22]
The review discusses rat studies of fear, escape, and avoidance, including different dopamine patterns in the accumbens core and shell, while leaving the precise information encoded during avoidance unresolved. [22]
This is a review, not a new experiment demonstrating canine training outcomes; a dopamine change alone does not establish equivalent emotional experiences or validate claims of effective, fear-free use of aversive dog-training methods. [22]
