Source: Reindl, V., et al. Conducting Hyperscanning Experiments with Functional Near-Infrared Spectroscopy. J. Vis. Exp. (2019) This video demonstrates the use of functional near-infrared spectroscopy (fNIRS) to measure brain activity during social interactions. Participants engage in a coordinated task that increases activity in the prefrontal cortex, a region critical for social behavior, while the system detects changes in light absorption due to blood oxygenation. By analyzing the synchrony...

This video demonstrates a method to assess functional neuromuscular junctions. Using a bioreactor containing muscle tissue and motor neurons, along with fluorescent microscopy, the light-sensitive channels in the neurons are stimulated to generate electrical signals, causing muscle fiber contractions.

Video-oculography is a very quantitative method to investigate ocular motor performance as well as motor learning. Here, we describe how to measure video-oculography in mice. Applying this technique on normal, pharmacologically-treated or genetically modified mice is a powerful research tool to explore the underlying physiology of motor behaviors.

Source: Vy M. Dong and Zhiwei Chen, Department of Chemistry, University of California, Irvine, CA This experiment will demonstrate the use of infrared (IR) spectroscopy (also known as vibrational spectroscopy) to elucidate the identity of an unknown compound by identifying the functional group(s) present. IR spectra will be obtained on an IR spectrometer using the attenuated total reflection (ATR) sampling technique with a neat sample of the unknown.
FAQs
Infrared video recording relies on a camera sensitive to infrared wavelengths and illumination from near-infrared sources. The illuminators provide energy that reflects from the subject and reaches the camera, allowing movement to be recorded when ordinary white light is absent. Because the recording does not depend on visible illumination, observation can continue in darkness without adding ordinary white-light exposure.
Near-infrared illumination matters because it supplies the light needed for imaging while remaining invisible or minimally visible to the observed animal. This can reduce the chance that lighting changes the behavior being measured. The resulting footage is therefore useful when researchers need activity records under darkness or when ordinary white light could alter behavioral responses.
It creates a record that can be reviewed for behavioral coding and processed through automated tracking. Those outputs can support measurements of movement, activity, social interactions, and locomotion rather than relying only on an observer’s presence. Continuous recording also preserves behavior across extended periods, allowing patterns to be examined in relation to environmental conditions.
A workflow combines an infrared-sensitive camera with near-infrared illumination, records activity during low-light or dark periods, and then examines footage through behavioral coding, automated tracking, or quantitative analysis. The same recording can document individual movement and interactions over time, making it possible to extend observation beyond daylight and reduce observer disturbance.
Infrared video recording is especially useful for studies of nocturnal activity, when behavior occurs outside ordinary daylight observation periods. It also supports monitoring in laboratory and natural settings, where researchers may need to follow locomotion, social interactions, or changes associated with environmental conditions. By extending observation into darkness, the technique broadens the time range available for behavioral study.
Because footage can be collected continuously, researchers can examine observed activity and movement in relation to environmental conditions represented in the study. The recordings preserve evidence of locomotion, social interaction, and other activity for later coding or quantitative analysis. This makes the method relevant when the research question concerns how behavior varies over time rather than at a single observation.
