**3.2. Evaluation of the correct placement of the cannula**

After all experiments finished, animals were decapitated and the brains were removed. We checked the placement of the cannulas histologically whether they were placed to the amygdala of the brain or not. Figure 24 represents a histological section of a brain which the cannula was placed correctly.

**Figure 24.** The figure represents the amydala region of the brain where the injections were applied. Blue colored region of the brain represents the amygdala region. (Reproduced with permission from Karakas et al.; published by Elsevier, 2011a.)
