Auditory Sensitivity of a Chinese River Dolphin, ,es, however, have suggested that the auditory and vestibular systems of baiji are relatively underdeveloped in comparison to those of some other dolphins, such as . and . (Feng et al., 1989). The objective of this paper is to estimate baiji’s hearing capability by determining its auditory thresholds using behavioral methods.

Detection of Tone Glides by the Beluga Whaleesholds for tone glides in the beluga whale three types of tone pulses were used: continuous frequency (CF) tones, linear frequency modulated (LFM) tones, and linear period modulated (LPM) tones. These three pulse types can be expressed mathematically as follows (Kroszczynski, 1969).

Selective Hearing Adaptation to Paired Pulses in ,e and amplitude domains. In the auditory system, the synthesis of a range axis, which has no corresponding anatomical precursor in the periphery, is suggestive of the methods by which sensory information may be extracted and displayed in the brain.

However, there is only limited information available on the visual system of cetaceans. Since the visual system is primarily depending on the structure of the eye, it is necessary to examine the qualitative character of the eye to understand the visual system.

Morphological and Histochemical Features of Odontocete Visual Neocortex: Immunocytochemical Analysisanularization of the neocortex. In the whale neocortex layer I comprises approximately one-third of total cortical thickness, whereas layer II is thin but markedly accentuated due to the high numerical density of intensively stained neurons.
