Ontogeny of auditory brainstem responses in the bat, Phyllostomus discolor
Hearing Research, 2019Hearing is the primary sensory modality in bats, but its development is poorly studied. For newborns, hearing appears essential in maintaining contact with their mothers and to develop echolocation abilities. Here we measured auditory brainstem responses

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.

Simulated head related transfer function of the phyllostomid bat Phyllostomus discolor.
The Journal of the Acoustical Society of America, 2008This paper presents a calculation of the head related transfer function (HRTF) for the frontal hemisphere of the phyllostomid bat Phyllostomus discolor using an acoustic field simulation tool based on the boundary element method. From the calculated HRTF results, binaural interaural intensity differences (IIDs) are derived.

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.

The auditory cortex of the bat Phyllostomus discolor [PDF]
, 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.

The orientation behaviour of bats (Phyllostomus discolor, Phyllostomidae), flying inside an octagonal "roost-like" chamber (phi: 100 cm; h: 150 cm) was examined. It has been shown that the bats begin turning manoeuvres during flight by turning their head towards the direction they intend to proceed to.

The ventilatory and metabolic responses of lesser spear-nosed bats to hypoxia and hypercapnia were measured to determine whether these corresponded to preliminary allometries and a positive relationship between hypoxic ventilatory threshold and P50.

AbstractBats have a well‐developed spatial memory, which enables them to navigate even when the conditions are extremely unfavourable for orientation. However, if they were to adhere too strictly to a flight path planned from memory and independent of exteroceptive control, they would be in danger of colliding with unexpected obstacles.
