Conventional computer hardware can not generate visual stimuli with sufficiently high grayscale resolution and measure response times with sufficient accuracy. We describe how to use the VideoSwitcher to produce high-resolution monochromatic displays, and the RTbox to measure response times with high accuracy on conventional computer hardware.

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.

This protocol presents the configuration of a compression test device capable of precisely measuring the mechanical properties of microstructures in the small-strain region, along with a systematic method for compression testing using this device. The proposed device can be used to analyze various microstructures and the mechanical behavior of polymer-based materials.
FAQs
Standardized protocols make the stimulus, response requirement, and timing procedure more consistent across trials. Repeated measurements help assess whether an observed result is reliable rather than an artifact of a single response. This consistency is important when comparing performance across assessments or examining changes associated with neurological conditions, medication effects, fatigue, or recovery.
The stimulus modality determines which sensory input initiates the measured response. Visual, auditory, and tactile testing can therefore provide information about different sensory pathways while also engaging cognitive processing and motor output. Selecting a modality that matches the clinical or research question helps clarify which part of the response sequence the assessment is intended to examine.
Response times may change alongside neurological conditions, medication effects, fatigue, or recovery. These influences can affect cognitive processing, motor function, or sensory pathways, producing measurable differences in performance. Repeating the assessment under a standardized protocol helps researchers and clinicians evaluate whether a change is consistent and relevant to the condition or circumstance being examined.
A typical procedure defines the stimulus and the event that counts as a response, then presents controlled visual, auditory, or tactile signals. Specialized software or sensors record the interval until the participant presses a button, moves, speaks, or produces another predefined response. Multiple trials can then be collected to improve measurement reliability.
Response time testing may use specialized software, sensors, or both, depending on the response being recorded. A button press, movement, speech response, or another predefined event can serve as the recorded endpoint. The equipment must connect the controlled stimulus with a precisely identified response so the interval can be quantified consistently.
This approach is useful when clinicians or researchers need an objective indicator of how quickly a person or physiological system responds. It can support assessment of cognitive processing, motor function, and sensory pathways, while also tracking effects associated with neurological conditions, medication, fatigue, or recovery. Standardized repeated testing makes it suitable for clinical assessment and research comparisons.
