Figure 2.
Freezing behavior of the SOM-GAD67 mice and control mice in the contextual conditioned fear test. The mice were subjected to either 0.2 mA (SOM-GAD67; n = 7, control; n = 7) or 0.4 mA (SOM-GAD67; n = 6, control; n = 4) foot-shocks in the conditioning session. Twenty-four hours later, the mice were returned to the same chamber, and freezing behavior was measured for 6 min without foot-shock presentation. The percent duration of freezing is shown. Data represent the means + SE.
