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.

(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.

A novel motion-based acuity test that allows the assessment of central and peripheral visual processing in low-vision and healthy individuals, along with goggles limiting peripheral vision compatible with MRI protocols, are described here. This method offers a comprehensive vision assessment for functional impairments and dysfunctions of the visual system.
FAQs
Frequency and intensity provide different kinds of auditory information. Frequency supports judgments about pitch, whereas intensity contributes to judgments of loudness. Auditory acuity depends on sensitivity to both dimensions rather than on a single measure of hearing. Examining them separately helps psychologists determine whether a person has difficulty detecting sound, distinguishing sounds, or interpreting differences in their sensory features.
Detection thresholds indicate the minimum level at which a person can detect a sound, while discrimination tasks examine whether the person can distinguish between sounds that differ in features such as pitch, loudness, or timing. These measures address different stages of auditory processing. Together, they provide a more informative picture than either simple sound detection or discrimination alone.
Timing helps listeners identify differences between sounds and contributes to how auditory signals are interpreted. A person may detect a sound yet show difficulty distinguishing sounds that differ in when they occur. In psychological research, controlled timing differences can therefore reveal aspects of auditory processing that are not captured by measures focused only on frequency or intensity.
Auditory acuity findings can vary with developmental stage, aging, attention, and hearing-related changes. These factors may influence how effectively a person detects sounds, discriminates among them, or interprets speech and other signals. Psychology researchers consider such variation when studying sensory processing, because performance differences may reflect changes in perception and processing rather than a single uniform ability.
Researchers commonly present controlled sounds and measure detection thresholds, discrimination performance, or responses to speech and other selected auditory stimuli. The specific task determines whether the study focuses on noticing a signal, identifying a difference in pitch, loudness, or timing, or interpreting meaningful sound. Comparing responses across tasks can clarify how auditory information supports behavior and communication.
Auditory acuity measures are useful when researchers examine how sensory processing relates to learning, communication, social interaction, and everyday decision-making. They also support studies of perception, attention, development, aging, and hearing-related changes. Speech-based responses can connect auditory performance with communication, while controlled nonspeech sounds can help isolate particular aspects of sensory discrimination and interpretation.
