Contextual fear learning and memory differ between stress coping styles in zebrafish.

ABSTRACT: Animals frequently overcome stressors and the ability to learn and recall these salient experiences is essential to an individual's survival. As part of an animal's stress coping style, behavioral and physiological responses to stressors are often consistent across contexts and time. However, we are only beginning to understand how cognitive traits can be biased by different coping styles. Here we investigate learning and memory differences in zebrafish (Danio rerio) displaying proactive and reactive stress coping styles. We assessed learning rate and memory duration using an associative fear conditioning paradigm that trained zebrafish to associate a context with exposure to a natural olfactory alarm cue. Our results show that both proactive and reactive zebrafish learn and remember this
