Communication between two animals occurs when one animal transmits an information signal that causes a change in the animal that receives the information. Organisms communicate with one another in a host of different ways. Signals can be auditory, chemical, visual, tactile, or a combination of these. Communication is a critical behavioral adaptation that promotes survival, growth, and reproduction. Types of Communication A common form of communication is visual. Visual communication can be...

Auditory brainstem neurons of avians and mammals are specialized for fast neural encoding, a fundamental process for normal hearing functions. These neurons arise from distinct precursors of embryonic hindbrain. We present techniques utilizing electroporation to express genes in the hindbrain of chicken embryos to study gene function during auditory development.

Source: Laboratories of Jonas T. Kaplan and Sarah I. Gimbel—University of Southern California Imagine the sound of a bell ringing. What is happening in the brain when we conjure up a sound like this in the "mind's ear?" There is growing evidence that the brain uses the same mechanisms for imagination that it uses for perception.1 For example, when imagining visual images, the visual cortex becomes activated, and when imagining sounds, the auditory cortex is engaged. However, to what extent are...

Source: Lee, D., et. al. Modified Experimental Conditions for Noise-Induced Hearing Loss in Mice and Assessment of Hearing Function and Outer Hair Cell Damage. J. Vis. Exp. (2023)This video demonstrates the measurement of auditory brainstem response (ABR) in a mouse. Electrodes are placed on the head, behind the ear, and near the tail of an anesthetized mouse. Acoustic stimuli at various intensities are delivered, and electric signals generated are recorded as waveforms.

FAQs
These three signal properties provide different kinds of information. Frequency describes sound wave characteristics, amplitude reflects signal strength, and timing indicates when acoustic events occur. Sensory systems detect these features and convert them into neural information, allowing receivers to interpret calls in relation to identity, reproductive status, territory, or alarm. Together, they support behaviorally relevant signal interpretation.
Sound-producing structures generate vibrations, but those vibrations must travel through a medium before reaching a receiver. The transmission stage therefore links the signal producer with the sensory system that detects it. Studying this sequence helps biologists connect biomechanics, which examines how structures produce movement, with sensory biology, which examines how receivers process acoustic information.
The same general types of acoustic signals can carry different biological significance depending on the interaction and surroundings. Receivers interpret sounds within social and environmental contexts, which helps explain responses related to identity, reproduction, territory, or danger. Context is therefore essential for connecting a signal's physical properties with the behavior it coordinates.
A useful analysis follows the signal from production to interpretation: identify the structure generating the vibration, consider how the sound travels through a medium, examine sensory detection of frequency, amplitude, and timing, and relate the resulting neural information to behavior. This pathway integrates biomechanics, sensory biology, and behavioral observation without treating sound as an isolated physical event.
Acoustic signaling can support several types of interaction, including locating resources, avoiding danger, and maintaining social relationships. In animals, calls and other vocalizations may also communicate identity, reproductive status, territory, or alarm. Examining which behavior follows a signal helps researchers connect measurable acoustic features with the biological function of communication.
Auditory communication provides a way to study how anatomy, sensory systems, behavior, and habitat interact. Researchers can use it to examine how acoustic systems support animal interactions and how communication adapts to changing habitats. Its value extends beyond sound production because it links the mechanisms of signaling with ecological conditions and evolutionary change.
