The protocol video describes establishing a whole-cell patch clamp for electrophysiological recording from the sensory neurons of the vomeronasal organ (VNO) in mice. A coronal VNO slice with fluorescently labeled sensory neurons is placed in a recording setup. A labeled neuron is patched with a recording pipette in a whole-cell configuration for electrophysiological recording in response to chemical stimuli.

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.

Transgenic mice have been extremely useful in ascribing physiological function to genes. As such, research in general, and functional studies of airway, in particular, have undergone a remarkable shift toward murine models. Here we provide protocols for in vitro trachea constriction studies to evaluate smooth muscle function in murine airway.
FAQs
The Venus signal is produced when regulatory elements associated with Fpr-rs3 activate the reporter construct. Fluorescence therefore provides a visible readout of cells linked to Fpr-rs3 expression, rather than relying only on anatomical appearance. Researchers can use this signal to locate gene-defined populations in neural tissue and examine their organization within specific regions.
Patterns of Venus-positive cells can show where Fpr-rs3-expressing populations are concentrated, dispersed, or arranged across tissue sections. This spatial information helps researchers map the distribution and organization of a gene-defined population. Comparing these patterns across neural regions can connect Fpr-rs3 expression with particular anatomical structures and support focused studies of sensory-related circuitry.
A gene-defined population gives researchers a molecular reference for examining neural cells that may share a particular functional or circuit-related identity. In Fpr-rs3 studies, labeling permits gene expression to be considered alongside cell location, neural connections, sensory processing, and behavior. This combination can provide more specific biological context than studying neural tissue only by gross anatomy.
The same fluorescent labeling can be examined in tissue sections to determine where Fpr-rs3-associated cells occur, or used during neural circuitry studies to investigate their connections. These approaches answer complementary questions: tissue analysis emphasizes distribution and organization, whereas circuit analysis addresses how labeled populations relate to connected neural structures. Together, they connect cellular identity with network arrangement.
A study can begin by examining neural tissue from the mice for Venus fluorescence, identifying labeled cells in tissue sections, and documenting their distribution. Researchers can then analyze the labeled population in relation to neural circuitry, sensory processing, or behavior, depending on the study design. This workflow moves from cell identification to anatomical and functional interpretation.
These mice are suited to studies that need to locate and follow Fpr-rs3-expressing cells, including cell-type identification, circuit tracing, and mapping of neural populations. The model is particularly relevant when researchers want to examine olfactory functions or other sensory processes. Fluorescent labeling provides a consistent way to connect those questions with defined cellular populations.
By identifying cells associated with Fpr-rs3 expression, researchers can examine where those cells occur and how their connections fit within neural circuitry. They can then interpret that anatomical information alongside studies of sensory processing or behavior. In this way, the model supports investigation of whether a gene-defined population is relevant to olfactory or other neural functions.
