“…The perceived loudness may have differed between the 22 kHz USVs and the 50 kHz USV because the behavioral hearing threshold and the electrophysiological detection threshold are lower for 22 kHz auditory stimuli than for 50 kHz stimuli (Borg, 1982;Kelly & Masterton, 1977;Gourevitch, 1965;Gourevitch & Hack, 1966;Sally & Kelly, 1988). However, the loudness of all four USVs was well above the detection threshold, as demonstrated by subsequent conditioning (see Experiment 2).…”

Rodent ultrasonic vocalizations (USVs) are ethologically critical social signals. Rats emit 22 kHz USVs and 50 kHz USVs, respectively, in conjunction with negative and positive affective states. Little is known about what controls emotional reactivity to these social signals. Using male SpragueDawley rats, we examined unconditional and conditional freezing behavior in response to the following auditory stimuli: three 22 kHz USVs, a discontinuous tone whose frequency and on-off pattern matched one of the USVs, a continuous tone with the same or lower frequencies, a 4 kHz discontinuous tone with an on-off pattern matched to one of the USVs, and a 50 kHz USV. There were no differences among these stimuli in terms of the unconditional elicitation of freezing behavior. Thus, the stimuli were equally neutral before conditioning. During differential fear conditioning, one of these stimuli (the CS + ) always co-terminated with a footshock unconditional stimulus (US) and another stimulus (the CS − ) was explicitly unpaired with the US. There were no significant differences among these cues in CS + -elicited freezing behavior. Thus, the stimuli were equally salient or effective as cues in supporting fear conditioning. When the CS + was a 22 kHz USV or a similar stimulus, rats discriminated based on the principal frequency and/or the temporal pattern of the stimulus. However, when these same stimuli served as the CS − , discrimination failed due to generalization from the CS + . Thus, the stimuli differed markedly in the specificity of conditioning. This strikingly asymmetrical stimulus generalization is a novel bias in discrimination.

“…In addition, the previously mentioned wide auditory sensitivity range for gerbils (Finck & Sofouglu, 1966) is superior to that of other small rodents such as the rat (Crowley, Hepp-Raymond, Tabowitz, & Palin;Gourevitch & Hack, 1966), the hamster (Finck & Houberman, 1965), as well as the mouse (Mikaelian, Alford, & Ruben, 1965).…”

“…This may be attributable to the anatomo-functional properties of the chochlea, with a dis tinct tonotopical localization at the high and the middle frequencies but with poorer cor relations of anatomical frequency resolution at low frequencies localized at the cochlear apex [16]. All ABR-based thresholds are, however, 10-30 dB poorer than behaviourally measured thresholds [10,11,14,17,18], The highest degree of normal auditory sensitivity in our study was around 12-20 kHz and accords with previous data in the literature. It was also in this frequency region that significant mean differences were found between 3-month-old and old normal rats.…”

Normative data for frequency-specific ( ± 100 Hz) auditory brainstem response (ABR) thresholds were determined in 60 normal healthy 3-month-old, 5 normal 22-month-old and 6 alcohol-addicted 22-month-old Sprague Dawley rats. The highest degree of auditory sensitivity was in the range of 12–20 kHz. These frequencies showed significant mean differences between the 3-month-old and the old normal rats. In contrast, alcohol-addicted old rats did not reveal any significant threshold changes as compared with either normal old or 3-month-old rats.
