Figure 2. Prolonged RST elevated corticosterone levels throughout the stress period.

Corticosterone levels were determined during the stress period (solid bars, Day 0–28) and following stress cessation (hashed bars, Day 29–42). For each data point, n = 5–15 individuals. Data shown is mean +SEM. *p<.05; **p<.0001. Data were collected without repeated sampling of individuals.
