Two weeks following single prolonged stress (SPS), dopamine (DA) levels in the nucleus accumbens were measured in SPS-exposed (n = 5) and control (n = 6) rats by in vivo microdialysis. Samples were collected over seven 10-minute periods: baseline (Period 1–3), K+-evoked stimulation (75 mM; Period 4), and post-stimulation recovery (Periods 5–7. Data presented as mean and S.E.M. *** - p < 0.001.
