We describe protocols for using the wide field-of-view nematode tracking platform (WF-NTP), which enables high-throughput phenotypic characterization of large populations of Caenorhabditis elegans. These protocols can be used to characterize subtle behavioral changes in mutant strains or in response to pharmacological treatment in a highly scalable fashion.

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University In a staggeringly complex and engaging world, it is crucial to selectively process some stimuli at the expense of others. Experimental psychologists call this ability attention. Specifically, visual attention refers to the ability to selectively process aspects of a visual scene. Many paradigms used to study visual attention involve brief, punctuated, and repeated trials. However, everyday situations often place sustained demands...

Eye Tracking in Cognitive Experiments

Eye tracking as the name suggests involves tracking of eye-movements. It is a non-invasive, sensitive tool that quantifies and measures eye-movements to describe an individuals' cognitive state. An eye-movement between two fixation points is called a saccade, which is one of the fastest motor movements in our body. By observing the profiles of these eye movements, scientists can better understand neural deficits in patients with cognitive impairments. In this video, we will first look at an...

We have developed a video-rate tracking microscope system that can record and quantify C. elegans behavior at high resolution and high speeds. We have also developed computational methods to reduce the dimensionality of the worm images to a fundamental set of measurements that completely describe the shape of the worm.

Eye tracking has long been used to study gaze patterns in typically-developing individuals, but recent technological advancements have made its use with clinical populations, including autism, more feasible. While eye-tracking young children with autism can offer insight into early symptom manifestations, it involves methodological challenges. Suggestions for best practices are provided.

Each tool captures a different aspect of an organism’s activity. Direct observation can document behavior, while visible markers, radio transmitters, GPS devices, camera traps, and other sensors can record location, movement, or environmental conditions. Selecting among these approaches determines whether the resulting evidence emphasizes individual behavior, spatial patterns, environmental change, or a combination of these factors.
Repeated observations show how organisms and populations change rather than providing only a single snapshot. Time-based records can reveal migration routes, shifts in habitat use, territory patterns, social interactions, and population changes. This perspective helps researchers connect biological activity with changing environmental conditions and identify patterns that may not be visible during one observation period.
Field tracking places records of location, movement, and behavior alongside measurements or observations of environmental conditions. Comparing these records can show how organisms use habitats and how their activities change as surroundings change. In biology, that connection helps explain movement patterns, habitat preferences, and population responses within natural ecosystems.
A study begins by identifying the organisms, population, or biological event to monitor and selecting a suitable way to follow it. Researchers then gather observations through direct viewing, markers, transmitters, GPS devices, camera traps, or sensors. Recording movement, location, behavior, and environmental conditions over time produces evidence that can be examined for ecological patterns.
Researchers use Field Tracking when they need evidence of how living systems function in natural environments. Following organisms in place preserves information about habitat use, migration, territory, social interactions, and responses to environmental change. This approach is especially relevant when laboratory conditions cannot show how behavior and movement are shaped by the surrounding ecosystem.
The resulting records can guide ecological research, wildlife management, disease surveillance, and conservation. By identifying migration routes, important habitats, population changes, and relationships between organisms and their surroundings, field tracking helps reveal where protection may be most needed. It therefore connects biological observations with decisions about managing species and ecosystems.
