Chewing Prevents Stress-Induced Hippocampal LTD Formation and Anxiety-Related Behaviors: A Possible Role of the Dopaminergic System

Figure 4

Effect of SCH23390 on exploratory behavior at 60 min after stress exposure. The number of animals administered SCH23390 (0.3 mg/kg i.p.) was in the OFT and (9, 8, 8) in the EPM for (CT, ST, and SC) groups, respectively. Data of “no treatment” were taken from Figure 2 and shown for comparison. Asterisks indicate statistically significant differences (, ).
