Control of echolocation pulses by neurons of the nucleus ambiguus in the rufous horseshoe bat, Rhinolophus rouxi [PDF]
, 1986 1. Horseradish peroxidase was applied by iontophoretic injections to physiologically identified regions of the laryngeal motor nucleus, the nucleus ambiguus in the CF/FM batRhinolophus rouxi. 2.

BiomimeticsIn this paper, we introduce SonoNERFs, a novel approach that adapts Neural Radiance Fields (NeRFs) to model and understand the echolocation process in bats, focusing on the challenges posed by acoustic data interpretation without phase information ...

Molecular Ecology Resources, EarlyView.ABSTRACT Many studies have proposed various comparative genomic methods to probe the molecular basis for adaptive functional convergence between species, conventionally by detecting the convergence of amino acid states between orthologous protein sequences of these species or lineages.

Development of echolocation calls and neural selectivity for echolocation calls in the pallid bat [PDF]
Developmental Neurobiology, 2014 ABSTRACTStudies of birdsongs and neural selectivity for songs have provided important insights into principles of concurrent behavioral and auditory system development. Relatively little is known about mammalian auditory system development in terms of vocalizations or other behaviorally relevant sounds.

Storage of Doppler-Shift Information in the Echolocation System of the "CF-FM"-Bat, Rhinolophus ferrumequinum [PDF]
, 1976 The greater horseshoe bat (Rhinolophus ferrumequinum) emits echolocation sounds consisting of a long constant-frequency (CF) component preceeded and followed by a short frequency-modulated (FM) component. When an echo returns with an upward Doppler-shift,

Frontiers in Marine ScienceGoose-beaked whales (Ziphius cavirostris) are deep-diving cetaceans known for their elusive nature and specialized foraging behavior. In 2019 and 2020, six telemetry tags were deployed on these whales in Southern California, resulting in 395 h of ...

Let's stop measuring animal sound frequencies in hertz
Methods in Ecology and Evolution, EarlyView.Abstract Research on the function and evolution of animal sounds typically analyses sound frequency on a linear scale (Hz), despite the perception and modulation of sound frequency by animals being better described with an equal‐ratios scale (logHz). Using a linear frequency scale causes bias in analyses, and distorts the visual representation of sound

A Device for Human Ultrasonic Echolocation [PDF]
IEEE Transactions on Biomedical Engineering, 2015 We present a device that combines principles of ultrasonic echolocation and spatial hearing to provide human users with environmental cues that are 1) not otherwise available to the human auditory system, and 2) richer in object and spatial information than the more heavily processed sonar cues of other assistive devices.

Optical flow sensing and the inverse perception problem for flying bats [PDF]
, 2013 The movements of birds, bats, and other flying species are governed by complex sensorimotor systems that allow the animals to react to stationary environmental features as well as to wind disturbances, other animals in nearby airspace, and a wide variety

The jamming avoidance response in echolocating bats
Communicative & Integrative Biology, 2019 Bats face many sources of acoustic interference in their natural environments, including other bats and potential prey items that affect their ability to interpret the returning echoes of their biosonar signals.
