Fear Conditioned Discrimination of Frequency Modulated Sweeps within Species-Specific Calls of Mustached Bats
Figure 6
Cumulative line plots for representative examples of peri-stimulus HRs in response to conditioning with three different FMs.
CS+ was a steep DFM (40 to 30 kHz sweep in 10 ms; rate 1.0 kHz/ms) FMs used as CS− differed (A) in direction (UFM), (B) in duration (100 ms) and rate (0.1 kHz/ms), and (C) in bandwidth (60 kHz to 10 kHz) and rate (0.5 kHz/ms). Line plots indicate instantaneous HR to the presentation of FM stimuli. Each black trace represents the HR in response to CS+, and each grey trace shows HR on trials with one of the three CS− stimuli. CS onset occurs at time zero (vertical dashed line). (D) Bar graph of data to show ∂HR for CS+ (black bar) versus CS− (grey bar) for each of the same three stimulus conditions. Error bars represent standard error of the mean.
