Fear Conditioned Discrimination of Frequency Modulated Sweeps within Species-Specific Calls of Mustached Bats

Social and echolocation vocalizations of bats contain different patterns of frequency modulations. An adult bat's ability to discriminate between various FM parameters, however, is not well established. Using changes in heart rate (HR) as a quantitative measure of associative learning, we demonstrate that mustached bats (Pteronotus parnellii) can be fear conditioned to linear frequency modulate...

DSCF neurons within the primary auditory cortex of the mustached bat process frequency modulations present within social calls.

Neurons in the Doppler-shifted constant frequency processing (DSCF) area in the primary auditory cortex of mustached bats, Pteronotus parnellii, are multifunctional, responding both to echolocation and communication sounds. Simultaneous presentation of a DSCF neuron's best low and high frequencies (BF(low) and BF(high), respectively) facilitates its response. BF(low) corresponds to a frequency ...

Neural Mechanisms for Call Processing in the Auditory Cortex of Mustached Bats: Frequency Modulated Sounds and their Lateralization

Speech processing is lateralized to the left hemisphere of the human brain, with some variation between sexes. Single unit electrophysiological recordings in the Doppler-shifted constant frequency processing (DSCF) sub-region of the mustached bat primary auditory cortex (A1) has revealed a left hemispheric advantage for processing species-specific (or conspecific) calls that at least superficia...

Simple Syllabic Calls Accompany Discrete Behavior Patterns in Captive Pteronotus parnellii: An Illustration of the Motivation-Structure Hypothesis

Mustached bats, Pteronotus parnellii, are highly social and vocal. Individuals of this species roost in tight clusters, and emit an acoustically rich repertoire of calls whose behavioral significance is largely unknown. We recorded their social and vocal behaviors within a colony housed under semi-natural conditions. We also quantified the spatial spread of each bat's roosting location and disc...

Target flutter rate discrimination by bats using frequency-modulated sonar sounds: behavior and signal processing models.

This study utilized psychophysical data and acoustical measurements of sonar echoes from artificial fluttering targets to develop insights to the information used by FM bats to discriminate the wingbeat rate of flying insects. Fluttering targets were produced by rotating blades that moved towards the bat, and the animal learned to discriminate between two rates of movement, a reference rate (30...
