Figure 2 Schematic overview of the configuration of the guider cannula for kainic acid (KA) injection and electroencephalogram (EEG) recording. KA was injected into the right amygdala (anterior −0.94 mm, medial −2.85 mm, dorsal 4.75 mm) (indicated by the arrow) through a guider cannula (indicated by the vertical black line). For EEG recording, a single stainless-steel screw was implanted in the right frontal lobe to be used as a recording electrode. Two screws then were mounted over the left and right occipital lobes to act as an EEG reference and ground electrode, respectively. Two other screws were implanted to affix the dental cement.
