PTSD and stress sensitisation: A tale of brain and body Part 2: Animal models
2007, Neuroscience and Biobehavioral ReviewsCitation Excerpt :One week after pre-shocks, the plasma corticosterone response to a novel cage is increased compared to non-shocked controls (Weinberg et al., 1980). Two weeks after pre-shocks, the corticosterone response to a reminder footshock (Madden et al., 1971), but also to a novel open field (Levine and Madden, 1973), to a startle apparatus (Chalmers et al., 1974) and to heat-induced pain (Caggiula et al., 1989), the ACTH response to noise in a novel cage (van Dijken et al., 1993) and the ACTH and corticosterone response to a novel, electrified prod in the home cage (Bruijnzeel et al., 2001a) are all greater than in non-shocked controls. Even though peak corticosterone levels in the noise test are not greater in previously shocked rats, the temporal dynamics seem to point to a faster negative feedback (van Dijken et al., 1993).
Exposure to repeated low-level formaldehyde in rats increases basal corticosterone levels and enhances the corticosterone response to subsequent formaldehyde
2001, Brain ResearchCitation Excerpt :Previous work examining the effect of repeated stress has demonstrated a variety of outcomes regarding CORT responses. Some studies have demonstrated no changes in CORT levels after repeated presentations of stress [23,36], while others have demonstrated a sensitization of basal and/or stress-induced CORT responses after repeated stress [17,23,26,27,34], and even a single pre-exposure to a stressor is sufficient to sensitize the CORT response [7]. However, the literature also supports an habituation response of CORT to repeated stressor presentation ( [21,22,25,51]; also, see [12] and references therein).
