To analyze corticosterone level in the serum of PTSD and non-PTSD rats, approximately 2 ml blood was obtained from the orbital sinus of the rat’s eye (28). Some samples were collected before training, and some after the testing. Consequently, the blood samples were centrifuged under the following settings: 3500 rpm for 5 min at room temperature. The serum was stored at -70 °C. Corticosterone was quantified using an Enzyme-linked immunosorbent assay (ELISA) DRG Corticosterone kit (Cat. No. EIA4164).
