Figure 2From: Roles of the anterior cingulate cortex and medial thalamus in short-term and long-term aversive information processing Effects of microinfusion of lidocaine into the ACC on the initial and retention latencies tested in the inhibitory avoidance task. a. Illustration of infusion cannula placements (arrow) in a histological coronal section. Placements shown are from all rats included in the final analysis (Saline, open circles; Lidocaine, filled inverted triangles). b. Lidocaine infusion into the ACC immediately after behavioral training disrupted retention of inhibitory avoidance learning tested 10 min later. Fisher's LSD test showed a significant difference between the saline and lidocaine microinfusion rats in the retention test 10 min after footshock (**p < 0.01).Back to article page
