Brainstem evoked response audiometry is an important tool in clinical neurophysiology. Nowadays, brainstem evoked response audiometry is also applied in the basic science and preclinical studies involving both pharmacological and genetic animal models. Here we provide a detailed description of how auditory brainstem responses can be successfully recorded and analyzed in mice.

Zebrafish are an excellent model to study muscle function and disease. During early embryogenesis zebrafish begin regular muscle contractions producing rhythmic swimming behavior, which is altered when the muscle is disrupted. Here we describe a touch-evoked response and locomotion assay to examine swimming performance as a measure of muscle function.

The preparation of acute brain slices from isolated hippocampi, as well as the simultaneous electrophysiological recordings of astrocytes and neurons in stratum radiatum during stimulation of schaffer collaterals is described. The pharmacological isolation of astroglial potassium and glutamate transporter currents is demonstrated.
FAQs
Repeated presentations make it possible to estimate the neural signal consistently associated with the stimulus. Synchronizing each presentation with the recording creates a common time reference, so responses can be aligned and averaged. Activity that varies independently across trials is reduced in the average, helping the time-locked response stand out from ongoing background activity.
Amplitude and latency provide complementary information about processing. Amplitude describes the size of the recorded response, whereas latency indicates when a response occurs relative to the stimulus. Examining both measures can show whether experimental conditions alter the strength or timing of neural processing, supporting comparisons of sensory, motor, or cognitive responses.
Synchronization links each stimulus presentation to a precise point in the neural recording. That alignment allows activity from separate trials to be combined according to its timing relative to the stimulus. Without this shared reference, the response could be difficult to distinguish from unrelated ongoing activity, limiting interpretation of when processing occurs.
Researchers can present defined sensory, motor, or cognitive conditions while recording neural activity, then compare the resulting time-related response measures. Differences in amplitude or latency may indicate that the conditions influence the strength or timing of processing. This design supports investigations of attention and perception as well as comparisons involving neurological disorders.
A basic workflow begins by selecting a defined stimulus and a recording approach, such as electroencephalography. Stimulus presentations are repeated and synchronized with the recording. The resulting trials are aligned in time and averaged, producing measures of the response’s amplitude and latency. These measurements can then be compared across experimental conditions.
These measurements can characterize sensory pathways and help investigate how attention and perception shape brain responses. They also provide an objective way to examine neural communication and assess changes associated with neurological disorders. Because the same framework applies to sensory, motor, and cognitive stimulation, it supports basic brain research and condition-based comparisons.
