Figure 4.
DL‐propranolol administration increased the NE levels in the dHPC, but not in the plasma. (a) Intrahippocampal injections of propranolol (5 μg) increased the NE levels in the dHPC. *p < .05, **p < .01 compared with the baseline; # p < .05 compared with the vehicle (n = 4 per group). (b) Intrahippocampal injections of propranolol (5 μg) induced a similar increase in both NE and epinephrine levels in the plasma compared with the saline group. *p < .05, **p < .01 compared with the baseline (n = 4 per group)
