Abstract
When an organism is exposed to a stressor, a series of behavioral changes occur that are thought to be of adaptive value. Among other things, the response style of an organism will narrow to those innate responses highest in the animal’s defensive repertoire (see belles, 1970) or to responses previously acquired in aversive situations. In addition, several neurochemical changes occur that may blunt the physical or psychological impact of the stressor, increase arousal or vigilance, or increase the animal’s ability to initiate and sustain defensive responses (see reviews in Zacharko and Anisman, 1989; Maier and Seligman, 1976; Weiss and Simson, 1985). However, there maybe occasions where these responses may have adverse consequences. For instance, when the response required to escape from the stressor is not part of the organism’s repertoire, the persistent adoption of these response styles may be counterproductive. Likewise, excessive utilization may reduce neurotransmitter stores, rendering the animal less able to deal with environmental demands. It has been our contention that many of the behavioral and physiological disturbances associated with acute and chronic uncontrollable stressors stem from the failure of adaptive neurochemical mechanisms. This chapter will outline some of the biochemical and behavioral consequences of stressors, particularly as they relate to an animal model of depression.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
