Effect of pre-acquisition dopamine D1 antagonist injection in the amygdala on the performances during the retention session. During the retention session, the SCH2339 group (n = 10) and the NaCl group (n = 9) received 5 presentations of the CS odor. The data were averaged over the 5 presentations. (A) Global effect: the data for freezing, respiration, and ultrasonic vocalization (USV) were averaged for the 5 s preceding odor onset (Pre-CS period) and compared to the average of the 40 s after odor onset (CS period). *significant difference with Pre-CS period (p = 0.01). (B) Temporal pattern: the temporal pattern for each parameter is represented with a 1-s bin precision, from 5 s prior to odor onset (green vertical line on each graph) to 40 s after. The blue vertical dashed line represents the time of shock arrival in the acquisition session. SCH23390 group: red filled circles (n = 10); NaCl group: blue filled circles (n = 9). #significant difference between the two experimental groups (p < 0.05); *significant difference with pre-odor baseline level (p < 0.05). The symbol preceding the asterisk refers to the experimental group.
