... of gillnet bycatch mitigation strategies that include auditory deterrent devices. We used both psychoacoustic and electrophysiological techniques to investigate underwater duck hearing in several species including the long-tailed duck ( Clangula hyemalis ), surf scoter ( Melanitta perspicillata ) and common...

.... Females displayed reduced affiliation in auditory-only conditions, but similar affiliation during visual and visual–acoustic conditions, demonstrating that visual–acoustic signaling from males is non-redundant but vision dominates. Using the neural activation marker cfos , we identified differential...

Recent studies of hearing in extant atympanate vertebrates have provided significant insights into the ancestral state(s) and the early evolution of the terrestrial tetrapod auditory...

... pathways to transmit sound from the environment to the ear. We used auditory brainstem response recording and laser vibrometry to assess the contributions of these extratympanic pathways for airborne sound in atympanic salamanders. We measured auditory sensitivity thresholds in eight species and observed...

... both conditions ( Fig. S5C,D ). The location of the approach points with CS ad and WN ad were more scattered than those under control conditions (CS ctl ) without pre-exposure to auditory stimuli ( Fig. S5F ). Crickets exposed to CS ad actually moved around the starting position ( Fig. S5B,C...

...T. Aran Mooney; Adam Smith; Ole Naesbye Larsen; Kirstin Anderson Hansen; Magnus Wahlberg; Marianne H. Rasmussen ABSTRACT Hearing is a primary sensory modality for birds. For seabirds, auditory data is challenging to obtain and hearing data are limited. Here, we present methods to measure seabird...

These behaviors are explained by a simple rule: flies steer away from the antenna with the larger vibration amplitude. Hearing Auditory...

...Karen P. Maruska; Allen F. Mensinger ABSTRACT The inner ear of fishes contains three paired otolithic end organs, the saccule, lagena and utricle, which function as biological accelerometers. The saccule is the largest otolith in most fishes and much of our current understanding on auditory...

...Timothy C. Tricas; Kelly S. Boyle ABSTRACT Fish produce context-specific sounds during social communication, but it is not known how acoustic behaviors have evolved in relation to specializations of the auditory system. Butterflyfishes (family Chaetodontidae) have a well-defined phylogeny...

Although there are no direct studies of dopamine release in cetaceans, we found that the timing of our VS is consistent with a response after dopamine release. We compared trained vocal responses to auditory stimuli with VS responses to SR sounds...

The complex tracheal shape of O. uninotatus also deviates from the known tube or horn shapes associated with simple band-pass or high-pass amplification of tracheal input to the tympana. Interestingly, while the anterior tympanal membrane shows directional...

... of the longfin squid ( Loligo pealeii ) using near-field acoustic and shaker-generated acceleration stimuli. Sound field pressure and particle motion components were measured from 30 to 10,000 Hz and acceleration stimuli were measured from 20 to 1000 Hz. Responses were determined using auditory evoked potentials...

... is the first investigation of peripheral coding strategies for spectral analysis in the auditory system in a non-teleost bony fish. We used a shaker system to simulate the particle motion component of sound during electrophysiological recordings of isolated single units from the eighth nerve innervating...

...Ian C. Hall; George V. Rebec; Laura M. Hurley SUMMARY Neuromodulation by serotonin (5-HT) could link behavioral state and environmental events with sensory processing. Within the auditory system, the presence of 5-HT alters the activity of neurons in the inferior colliculus (IC), but the conditions...

Previous physiological and neuroanatomical studies have indicated that binaural convergence is present in the ascending auditory...

They might also be able to hit a target that is intermittently moving while the owl is approaching. If so, there should be a critical...
