Laminar Distribution of Spectrotemporal Receptive Field Subtypes in the Primary Auditory Cortex of Echolocating Bats. [PDF]
Ann N Y Acad SciThis study examines how the bat auditory cortex evolved to process biosonar echoes during echolocation. Neurons in more superficial cortical layers exhibited more complex receptive fields matching the modulated acoustic patterns of echoes reflected from obstacles and prey, rather than just the bats' emitted pulses, suggesting that these cortical ...

Predicting ecology and hearing sensitivities in Parapontoporia-An extinct long-snouted dolphin. [PDF]
Anat Rec (Hoboken)Abstract Analyses of the cetacean (whale and dolphin) inner ear provide glimpses into the ecology and evolution of extinct and extant groups. The paleoecology of the long‐snouted odontocete (toothed whale) group, Parapontoporia, is primarily marine with its depositional context also suggesting freshwater tolerance.

Vocalization Characteristics of the Indo-Pacific Humpback Dolphins (<i>Sousa chinensis</i>) in Xiamen Bay With Insights on Regional Differences. [PDF]
Ecol EvolThe Indo‐Pacific humpback dolphin population in Xiamen Bay was divided into two geographically separated but socially associated communities inhabiting the West and East sub‐regions. Based on 3 years of boat‐based surveys, this study established baseline acoustic characteristics and investigated whether vocal patterns varied with habitat conditions ...

Hearing sensation levels of emitted biosonar clicks in an echolocating Atlantic bottlenose dolphin. [PDF]
PLoS ONE, 2012 Emitted biosonar clicks and auditory evoked potential (AEP) responses triggered by the clicks were synchronously recorded during echolocation in an Atlantic bottlenose dolphin (Tursiops truncatus) trained to wear suction-cup EEG electrodes and to detect ...

Noseleaf dynamics during pulse emission in horseshoe bats. [PDF]
PLoS ONE, 2012 Horseshoe bats emit their biosonar pulses nasally and diffract the outgoing ultrasonic waves by conspicuous structures that surrounded the nostrils. Here, we report quantitative experimental data on the motion of a prominent component of these structures,

Rapid jamming avoidance in biosonar [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2006 The sonar systems of bats and dolphins are in many ways superior to man-made sonar and radar systems, and considerable effort has been devoted to understanding the signal-processing strategies underlying these capabilities. A major feature determining the efficiency of sonar systems is the sensitivity to noise and jamming signals.
