Abstract
Cholecystokinin (CCK) is an abundant and widely distributed neuropeptide that plays a modulatory role in a variety of behaviours. This paper focuses on the role of CCK in modulating anxiety-related and reward-related behaviours in key brain regions of the amygdala and mesolimbic dopamine system, respectively. The role of CCK in mediating aspects of these behaviours has been studied in a variety of behavioural paradigms, but inconsistent results have led to confusion regarding the precise role of the receptor subtypes in mediating behaviour. The confusion in the literature may come in part from the diverse behavioural paradigms that are used, the differences in regional effects of CCK manipulations in different areas and at different receptor subtypes in these areas and the dependence of the behavioural outcome on the baseline state of arousal of the animal. Evidence on the role of CCK in anxiety-related and reward-related behaviours in various animal models indicates that CCK-B receptors in the basolateral amygdala are important mediators of anxiety-related behaviours and that CCK-A and CCK-B receptors in the nucleus accumbens are important in mediating different aspects of reward-related behaviour. Emphasis is placed upon the role of CCK as a neuromodulator that is recruited only under conditions of high frequency neuronal firing.

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
