2025
This protocol introduces vmTracking, a method that enables high-accuracy pose tracking in videos of multiple freely moving, markerless animals, even under crowded conditions where animals are densely grouped. This approach provides reliable data for analyzing social interactions that occur in semi-natural environments where animals can move freely.

What are Estimates?

It isn't easy to measure a parameter such as the mean height or the mean weight of a population. So, we draw samples from the population and calculate the mean height or mean weight of the individuals in the sample. This sample data acts as a representative measure of the population parameter. These sample statistics are known as estimates. The estimate for the mean of a sample is denoted by ͞x, whereas the mean of the population is designated as μ. Further, parameters such as the mean,...

The Precision of Visual Working Memory with Delayed Estimation

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University Human memory is limited. Throughout most of its history, experimental psychology has focused on investigating the discrete, quantitative limits of memory—how many individual pieces of information a person can remember. Recently, experimental psychologists have also become interested in more qualitative limits—how precisely is information stored? The concept of memory precision can be both intuitive and elusive at once. It is...

Estimation of k and VD of Aminoglycosides

Aminoglycosides are a class of antibiotics used to treat various bacterial infections. Clinicians must determine the elimination rate constant (k) and volume of distribution (VD) to optimize therapeutic efficacy and minimize toxicity. The k value represents the rate at which the drug is removed from the body, and the VD reflects the degree to which the drug distributes into body tissues. Accurately estimating these parameters allows healthcare professionals to tailor drug dosing to individual...

This protocol describes how to build a small and versatile video camera, and how to use videos obtained from it to train a neural network to track the position of an animal inside operant conditioning chambers. This is a valuable complement to standard analyses of data logs obtained from operant conditioning tests.
FAQs
The system learns from video frames that a user has annotated with specific anatomical points. A deep neural network extracts visual features associated with those labeled locations, then applies the learned relationships to previously unseen frames. This training-and-application process allows the same recording to yield continuous positional trajectories rather than requiring manual labeling of every frame.
DeepLabCut pose estimation derives body-part locations from visual information in the video instead of relying on physical markers attached to the subject. That distinction allows recordings to support measurements of posture, movement, coordination, and social interactions without introducing marker placement into the behavioral setup. The resulting trajectories can therefore serve as numerical inputs for quantitative analysis.
Tracked trajectories provide time-varying positions for selected anatomical keypoints. Researchers can use those numerical records to examine changes in posture, movement patterns, coordination between body parts, and interactions between individuals. Because the output converts complex recordings into structured measurements, it supports behavioral phenotyping and makes behavioral comparisons more reproducible than relying solely on qualitative video inspection.
A typical workflow begins with video recordings and user-labeled frames that identify the anatomical keypoints of interest. A deep neural network is trained on those examples, after which the learned visual features are applied to new frames. The estimated point locations are assembled into trajectories, which can then be analyzed for posture, movement, coordination, or social behavior.
Researchers can apply DeepLabCut pose estimation when they need quantitative measurements from complex animal or human behavior recordings. Supported uses include behavioral phenotyping, neuroscience, biomechanics, and animal welfare research. It is especially relevant when posture, movement, coordination, or social interactions are central outcomes, because the method converts video observations into numerical data that can be examined at greater scale.
In behavior research, the tracked positions of anatomical keypoints provide a way to quantify observable changes across recordings. Those measurements can describe movement and posture in animal or human subjects, while trajectories between individuals can represent social interactions. In animal welfare studies, this quantitative behavioral information can support systematic assessment rather than depending only on manual observation or descriptive judgments.
