Loss of the righting reflex has long served as a standard behavioral surrogate for unconsciousness, also called hypnosis, in laboratory animals. Alterations in volatile anesthetic sensitivity caused by pharmacological interventions can be detected with a carefully controlled high-throughput assessment system, which may be adapted for delivery of any inhaled therapeutic.

Utilizing luciferase and in vivo imaging systems (IVIS) as a novel means to identify disease endpoints before clinical developments occur. IVIS has allowed us to visualize in real time the invasion of encephalitic viruses over multiple days, providing a more accurate disease model for future study. It has also allowed us to identify the potential protective features of antivirals and vaccines faster than currently utilized animal models. The capability to utilize individual animals over...

Source: Kay Stewart, RVT, RLATG, CMAR; Valerie A. Schroeder, RVT, RLATG. University of Notre Dame, IN Animal records must be accurately maintained to ensure that data collection is correct. Records range from maintaining information on cage cards to having a detailed database with all of the relevant information on each animal. The primary component of recordkeeping is the individual identification of research animals. There are a variety of methods suitable for identifying mice and rats. This...

A passive unit derives electrical power from the radio waves emitted by an RFID reader. Its antenna receives the incoming energy, allowing the chip to operate without an internal battery. The chip then changes, or modulates, the returned signal so the reader can recover the stored identifier. This power arrangement supports identification without direct line of sight.
Active tags contain an internal battery, so they do not depend entirely on energy supplied by the reader. That independent power source allows the tag to transmit over greater distances than a passive transponder. The distinction matters when study designs require identification across a broader area, although the overview does not specify particular distance limits or operating conditions.
The antenna receives radio-frequency energy and participates in returning the response to the reader. The chip uses that available power, or its internal battery in an active tag, to process the stored digital identifier. By modulating and backscattering the signal, the transponder sends encoded information that links a detected object, animal, instrument, or device to its recorded identity.
RFID recognition does not require the reader and tagged item to maintain a direct line of sight. This allows identification when visual access is inconvenient or unavailable, while still associating a digital identifier with the item being detected. In neuroscience studies, that property can help connect observations to individually identified animals, materials, or devices during ongoing research workflows.
A transponder provides a persistent digital identifier that can be associated with an individual laboratory animal or research item across repeated observations. Researchers can therefore connect behavioral or physiological measurements to the same subject over time instead of treating each record as isolated. This supports longitudinal study management, improves data organization, and helps preserve links needed for reproducible analyses.
A study assigns a transponder identifier to the relevant animal, material, instrument, or device, then uses an RFID reader to detect and recover that identifier during research activities. The resulting identity is linked with behavioral or physiological measurements in the study records. This workflow helps organize observations by subject or item and supports consistent management of repeated data.
The overview identifies several possible targets: laboratory animals, experimental materials, and research devices. Using one system across these entities can help researchers associate recorded measurements or study activities with the correct subject, material, or instrument. The approach is especially relevant when experiments generate repeated observations that must remain connected to identifiable components throughout study management.
They strengthen the connection between a digital identity and the measurements collected during an experiment. When behavioral or physiological data remain linked to the appropriate animal, material, or device, researchers can organize records more reliably and manage longitudinal observations with greater consistency. That traceable organization supports reproducibility by reducing ambiguity about which study entity produced each recorded result.
