Separation and Its Effect on the Forced Swim Test In the Guinea Pig Early-life stress such as parental neglect, absence, or abandonment, has been hypothesized to increase the susceptibility for developing depression later in life via sensitization of stress-responsive physiological systems (e.g., pro-inflammatory cytokines, hypothalamic-pituitary-adrenal axis). Guinea pigs offer a potential model, but study has been limited to behavioral observations obtained during maternal separation tests. This thesis examined the generalization of this response by asking whether it would cross-sensitize to behavior in another depressive-related paradigm, the forced swim test. In three experiments, pups underwent three forced swim trials, in shallower …
