“…The F0 range over which the spatio-temporal representation of pitch is most effective in cat AN encompasses the 500–1000 Hz range of cat vocalizations (Brown et al, 1978; Shipley et al, 1991). What might be the corresponding range in humans?…”

The pitch of harmonic complex tones plays an important role in speech and music perception and the analysis of auditory scenes, yet traditional rate-place and temporal models for pitch processing provide only an incomplete description of the psychophysical data. To test physiologically a model based on spatiotemporal pitch cues created by the cochlear traveling wave (Shamma, 1985), we recorded from single fibers in the auditory nerve of anesthetized cat in response to harmonic complex tones with missing fundamentals and equalamplitude harmonics. We used the principle of scaling invariance in cochlear mechanics to infer the spatiotemporal response pattern to a given stimulus from a series of measurements made in a single fiber as a function of fundamental frequency F 0 . We found that spatiotemporal cues to resolved harmonics are available for F 0 values between 350 and 1100 Hz and that these cues are more robust than traditional rate-place cues at high stimulus levels. The lower F 0 limit is determined by the limited frequency selectivity of the cochlea, whereas the upper limit is caused by the degradation of phase locking to the stimulus fine structure at high frequencies. The spatiotemporal representation is consistent with the upper F 0 limit to the perception of the pitch of complex tones with a missing fundamental, and its effectiveness does not depend on the relative phase between resolved harmonics. The spatiotemporal representation is thus consistent with key trends in human psychophysics.

“…At the same time, a high prevalence of spatially tuned neurons in AAF and in the anterior ectosylvian sulcus (AES) was found Rauschecker and Korte 1993). These findings led to the hypothesis that PAF may be more suitable for the analysis of communication sounds with their slower FM rates (Brown et al 1978;Capranica 1972;Leppelsack 1983;Liberman et al 1967;Rauschecker 1997Rauschecker , 1998, whereas AAF and AES may be more specialized for the analysis of sound location. However, the conclusions from the cat work remained incomplete and purely hypothetical because no tests of call selectivity, for instance, were conducted and no direct comparison between areas was performed in the same animals.…”

Tian, Biao and Josef P. Rauschecker. Processing of frequencymodulated sounds in the lateral auditory belt cortex of the rhesus monkey. J Neurophysiol 92: 2993-3013, 2004; 10.1152/ jn.00472.2003. Single neurons were recorded from the lateral belt areas, anterolateral (AL), mediolateral (ML), and caudolateral (CL), of nonprimary auditory cortex in 4 adult rhesus monkeys under gas anesthesia, while the neurons were stimulated with frequency-modulated (FM) sweeps. Responses to FM sweeps, measured as the firing rate of the neurons, were invariably greater than those to tone bursts. In our stimuli, frequency changed linearly from low to high frequencies (FM direction "up") or high to low frequencies ("down") at varying speeds (FM rates). Neurons were highly selective to the rate and direction of the FM sweep. Significant differences were found between the 3 lateral belt areas with regard to their FM rate preferences: whereas neurons in ML responded to the whole range of FM rates, AL neurons responded better to slower FM rates in the range of naturally occurring communication sounds. CL neurons generally responded best to fast FM rates at a speed of several hundred Hz/ms, which have the broadest frequency spectrum. These selectivities are consistent with a role of AL in the decoding of communication sounds and of CL in the localization of sounds, which works best with broader bandwidths. Together, the results support the hypothesis of parallel streams for the processing of different aspects of sounds, including auditory objects and auditory space.

“…Litters from different females may be reared in the same nest and thus, may become mixed, which could make kin signatures essential for offspring recognition and offspring-directed maternal care [51]. Previous studies have already shown that kittens produce isolation calls when isolated from their mother [55,57-60] which evoke maternal behaviour [61]. Context and age-specific variations in the acoustic structure of kitten isolation calls have already been described but only for a few acoustic parameters [58,60], whereas to our knowledge no data on acoustically conveyed individual signatures in kitten isolation calls have been published.…”

Vocal correlates of sender-identity and arousal in the isolation calls of domestic kitten (Felis silvestris catus)

IntroductionHuman speech does not only communicate linguistic information but also paralinguistic features, e.g. information about the identity and the arousal state of the sender. Comparable morphological and physiological constraints on vocal production in mammals suggest the existence of commonalities encoding sender-identity and the arousal state of a sender across mammals. To explore this hypothesis and to investigate whether specific acoustic parameters encode for sender-identity while others encode for arousal, we studied infants of the domestic cat (Felis silvestris catus). Kittens are an excellent model for analysing vocal correlates of sender-identity and arousal. They strongly depend on the care of their mother. Thus, the acoustical conveyance of sender-identity and arousal may be important for their survival.ResultsWe recorded calls of 18 kittens in an experimentally-induced separation paradigm, where kittens were spatially separated from their mother and siblings. In the Low arousal condition, infants were just separated without any manipulation. In the High arousal condition infants were handled by the experimenter. Multi-parametric sound analyses revealed that kitten isolation calls are individually distinct and differ between the Low and High arousal conditions. Our results suggested that source- and filter-related parameters are important for encoding sender-identity, whereas time-, source- and tonality-related parameters are important for encoding arousal.ConclusionComparable findings in other mammalian lineages provide evidence for commonalities in non-verbal cues encoding sender-identity and arousal across mammals comparable to paralinguistic cues in humans. This favours the establishment of general concepts for voice recognition and emotions in humans and animals.
