The Masked ABR (mABR): a New Measurement Method for the Auditory Brainstem Response
The auditory brainstem response (ABR) is relatively non-invasive, and in many species, the only practical way to assess auditory sensitivity. The two main methods for measuring ABR are using either transients ...

From “ear” to there: a review of biorobotic models of auditory processing in lizards
The peripheral auditory system of lizards has been extensively studied, because of its remarkable directionality. In this paper, we review the research that has been performed on this system using a biorobotic...

Role of intracranial cavities in avian directional hearing
Whereas it is clear from anatomical studies that all birds have complex interaural canals connecting their middle ears, the effect of interaural coupling on directional hearing has been disputed. A reason for ...

Sound source localization and segregation with internally coupled ears: the treefrog model
Acoustic signaling plays key roles in mediating many of the reproductive and social behaviors of anurans (frogs and toads). Moreover, acoustic signaling often occurs at night, in structurally complex habitats,...

Animals and ICE: meaning, origin, and diversity
ICE stands for internally coupled ears. More than half of the terrestrial vertebrates, such as frogs, lizards, and birds, as well as many insects, are equipped with ICE that utilize an air-filled cavity connec...

Coupled ears in lizards and crocodilians
Lizard ears are coupled across the pharynx, and are very directional. In consequence all auditory responses should be directional, without a requirement for computation of sound source location. Crocodilian ea...

Low frequency eardrum directionality in the barn owl induced by sound transmission through the interaural canal
The middle ears of birds are typically connected by interaural cavities that form a cranial canal. Eardrums coupled in this manner may function as pressure difference receivers rather than pressure receivers. ...

The Malleable Middle Ear: An Underappreciated Player in the Evolution of Hearing in Vertebrates
The middle ear of tetrapods (limbed vertebrates) originated from nonauditory structures, and has been modified by adaptations arising from the lifestyle of the tetrapods. These accessory structures for the inn...

Chapter
Auditory Brain Stem Processing in Reptiles and Amphibians: Roles of Coupled Ears
Comparative approaches to the auditory system have yielded great insight into the evolution of sound localization circuits, particularly within the nonmammalian tetrapods. The fossil record demonstrates multip...

Importance of Hearing for Survival of Danio rerio (Zebrafish) in an Experimental Predator/Prey Environment
Throughout the past 10 years, there has been an increasing interest regarding the influence of man-made noise on life in the sea. Behavioral studies show that hearing in fish (and other animals) can be impaire...

Potential for Sound Sensitivity in Cephalopods
Hearing is a primary sense in many marine animals, and we now have a reasonable understanding of what stimuli generate clear responses, the frequency range of sensitivity, expected threshold values, and mechan...

Article
Acoustical Coupling of Lizard Eardrums
Lizard ears are clear examples of two-input pressure-difference receivers, with up to 40-dB differences in eardrum vibration amplitude in response to ipsi- and contralateral stimulus directions. The directiona...
