From: Multiple factors contribute to flight behaviors during fear conditioning
Tone intensity was the primary factor to trigger flight behaviors independent from the tone intensity used for the conditioning. (A) Averaged motions of each condition around the CS presentation by day are shown. G1 (upper row), G2 (lower row). (B) Averaged total motions, averaged percentages of freezing, and averaged jumps during the CS presentation of each trial are plotted. G1 (upper row), G2 (lower row). (C) Comparisons of motions, freezing, and jumps between G1 and G2. Averaged total motions, averaged percentages of freezing, and averaged total numbers of jumps by days are plotted. Each group exhibited more flight behavior on the day when the group was exposed to a louder tone. (D) Comparisons of ‘across-day ratio’ for motions, freezing, and jumps between G1 and G2. Each value is plotted as a gray circle. The horizontal red bars indicate the averages, and the vertical red bars indicate the S.E.M. of each group. G1 exhibited more flight behavior on day 3 than on day 4, while G2 showed the opposite. *Indicates p < 0.05.
