Psychophysical and neurophysiological hearing thresholds in the bat Phyllostomus discolor
Journal of Comparative Physiology A: Neuroethology, Sensory, Neural, and Behavioral Physiology, 2007(Uploaded by Plazi for the Bat Literature Project) Absolute hearing thresholds in the spear-nosed bat Phyllostomus discolor have been determined both with psychophysical and neurophysiological methods. Neurophysiological data have been obtained from two diVerent structures of the ascending auditory pathway, the inferior colliculus and the auditory ...

Detection of frequency modulation in the FM-bat Phyllostomus discolor
Journal of Comparative Physiology A: Neuroethology, Sensory, Neural, and Behavioral Physiology, 1996In a two-alternative forced-choice procedure lesser spear-nosed bats, Phyllostomus discolor, had to discriminate between a pure tone stimulus and a sinusoidally frequency-modulated signal generated at the same carrier frequency as the tone. Modulation depths of the SFM stimuli were reduced until the animals' performance dropped below the 75%-correct ...

Cochlear sensitivity in the lesser spear-nosed bat, Phyllostomus discolor
Journal of Comparative Physiology A: Neuroethology, Sensory, Neural, and Behavioral Physiology, 2004Behavioral auditory thresholds of Phyllostomus discolor are characterized by two threshold minima separated by an insensitive region at about 55 kHz (Esser and Daucher 1996). To investigate whether these characteristics are due to cochlear properties, we recorded distortion product otoacoustic emissions (DPOAEs) and calculated relative DPOAE threshold ...

The auditory cortex of the bat Phyllostomus discolor
, 2009 The auditory cortex is the acoustically responsive part of the neocortex and represents the highest level of processing of the ascending auditory pathway. The experiments described in this thesis were designed to study the auditory cortex of the microchiropteran bat Phyllostomus discolor with both, simple and complex acoustic stimuli.

Spectral directionality of the external ear of the lesser spear-nosed bat, Phyllostomus discolor
Hearing Research, 2003The directional dependence of sound pressure transformation of head and pinna has been measured in the phyllostomid bat Phyllostomus discolor for the frontal hemisphere using a maximum length sequence method. The azimuthal position of the axis of highest pinna gain came closer to the midsagital plane with increasing frequency.

Hearing in the FM-bat Phyllostomus discolor: a behavioral audiogram
Journal of Comparative Physiology A, 1996Absolute auditory thresholds of six adult lesser spear-nosed bats Phyllostomus discolor (Chiroptera, Phyllostomidae) were determined in a two-alternative forced-choice procedure. Behavioral response to pure tone stimuli could be elicited throughout the tested frequency range of 5-142 kHz.
