Object-oriented echo perception and cortical representation in the bat Phyllostomus discolor

The Journal of the Acoustical Society of America, 2008
Echolocating bats can identify three-dimensional objects exclusively through the analysis of acoustic echoes of their ultrasonic emissions. However, objects of the same structure can differ in size and the auditory system must achieve a size-invariant, normalized object representation for reliable object recognition.

An area sensitive to apparent acoustic motion in the auditory cortex of the bat Phyllostomus discolor

The Journal of the Acoustical Society of America, 2008
The processing of apparent acoustic motion was investigated in neurons in the auditory cortex of anaesthetized bats (Phyllostomus discolor). Apparent motion in the horizontal plane was generated by presenting pairs of pure tones with different interaural intensity differences (IIDs) and temporal separations, i.e. inter-pulse intervals (IPIs).

Discrimination of sinusoidally frequency-modulated sound signals mimicking species-specific communication calls in the FM-bat Phyllostomus discolor

Journal of Comparative Physiology A: Sensory, Neural, and Behavioral Physiology, 1997
In the lesser spear-nosed bat, Phyllostomus discolor, maternal directive calls are characterized by an individual type of sinusoidal frequency modulation (= SFM) pattern. Beside modulation frequency, modulation depth, carrier frequency, and number of modulation cycles per call contribute to the mother's vocal signature. Since juvenile P. discolor learn

A dietary analysis of Phyllostomus discolor with potential evidence of mammal predation

Therya Notes
Phyllostomus discolor is considered an omnivore, with a high consumption of nectar.  The consumption of vertebrates has never been documented in P. discolor.  However, there is a documented attack on Eptesicus furinalis, and frog remains were found under a colony of this bat.  We obtained a fecal sample from P.

Neuronale Kontrolle von Echoortungs- und Kommunikationslauten bei der Fledermaus Phyllostomus discolor

2009
Vokalisationen von Fledermäusen können in zwei Gruppen unterteilt werden: Kommunikationslaute und Echoortungslaute. Diese Arbeit wurde durchgeführt, um herauszufinden, ob in die Steuerung der unterschiedlichen Laute unterschiedliche Hirnstrukturen involviert sind.

Orientation by the Bat Phyllostomus discolor (Phyllostomidae) on the Return Flight to its Resting Place

Ethology, 1995
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.
