The Philippine tarsier, has a high-frequency limit of auditory sensitivity of approximately 91 kHz with a dominant frequency of 70 kHz.
The spatial perceptual features of human auditory system, for example, the perceptual sensitivity limits of human auditory system, have played important roles in the perceptual redundancy removal of spatial parameter quantization in SAC.
Pennington et al. 12 administered the Illinois Test of Psycholinguistic Abilities to 11 4-year-old females from the Denver cohort and found that they scored below normal limits on auditory association (d=1.2), visual association (0.8), visual closure (0.7), and auditory closure (1.9).
As the task difficulty increased with decreasing notch, resulting in poorer performance, we could tentatively say that task difficulty (or attentional load) did increase the proportional attentional effect or sensory gain, but only to a certain extent, which could even be related to the physiological limits of the human auditory system (the critical band).
Finally, analysis of cognition was limited to auditory verbal memory and executive function.
Similarly, comparison between auditory (AIS) and audiovisual (AISVIS) modalities demonstrated that the enhancement of mean response magnitude was limited to auditory stimuli (F1, 154 = 7.91, P = 0.006).
Recent human neuroimaging studies revealed that the functional hemispheric asymmetry of auditory processing was not limited to complex sound signals conveying specific meaning and rules (e.g. music and speech), but originated from the basic auditory processing level, namely, the temporal integration window (Poeppel 2003; Belin et al. 1998; Zatorre and Belin 2001; Zatorre et al. 2002).
5) What if it's not vPN1 acting as a low pass filter, but 35ms being the natural limit of the fly auditory system and in turn aPN1 integration?
Several factors have limited fMRI research in the auditory field, including some intrinsic features of auditory functional anatomy and some peculiar interactions between fMRI technique and audition.
Studies of auditory function in PCB- or MeHg-exposed humans are limited, but they do suggest that low-level prenatal exposure may impair hearing.
