Figure 2

The conditioned hyperactivity during the CS reactivation sessions.

Two days after the conditioning sessions, rats were transported into the locomotion chambers for a 20-min re-exposure trial on day 10. Immediately after re-exposure, rats were administered 10 mg/kg propranolol (Mor-R-Pro) or saline (Mor-R-Sal) and placed back into home cages. The non-reactivation control group (Mor-NR-Pro) received propranolol in home cages. The same intervention was repeated on day 11. * p < 0.05 compared with Sal group (day 10 and day 11); # p < 0.01 compared with Mor-R-Sal group (day 11).
