Zebrafish are emerging as a valuable model of dietary lipid processing and metabolic disease. Described are protocols of lipid-rich larval feeds, live imaging of dietary fluorescent lipid analogs, and quantification of food intake. These techniques can be applied to a variety of screening, imaging, and hypothesis driven inquiry techniques.

The feeding circuit in Drosophila melanogaster larvae serves a simple yet powerful model that allows changes in feeding rate to be correlated with alterations in the stomatogastric neural circuitry. This circuit is composed of central serotonergic neurons that send projections to the mouth hooks as well as the foregut.

Lyme disease is the most commonly-reported vector-borne disease in North America. The causative agent, Borrelia burgdorferi is a spirochete bacterium transmitted by Ixodid ticks. Transmission and detection of infection in animal models is optimized by the use of tick feeding, which we describe here.
FAQs
The grasper helps orient the experimenter toward nearby neural structures and provides a recognizable route for positioning instruments. This landmark-based approach can make targeting more precise than navigating through surrounding anatomy alone. By using the feeding apparatus to guide access, researchers can focus manipulation or measurement on feeding-related tissues while limiting unnecessary disturbance to adjacent structures.
Controlled positioning of fine tools determines whether an instrument exposes or contacts the intended tissue without disrupting nearby anatomy. Precise movement is therefore central to the method’s selectivity. Maintaining this control can improve the reliability of neural delivery, recording, stimulation, or imaging, especially when the preparation contains closely located structures or must retain aspects of normal feeding behavior.
This approach is most relevant when conventional access makes nearby neural structures difficult to reach. The feeding apparatus provides an alternative anatomical route that can reduce the need to disturb surrounding tissues. Its advantage is not simply physical access, but the combination of targeted positioning and anatomical preservation, which supports experiments requiring localized manipulation or measurement in feeding-related preparations.
Depending on the preparation and experimental objective, the route can support targeted delivery, neural recording, stimulation, or imaging. These operations use the same anatomical access principle but answer different questions about neural function. Delivery can manipulate a target, recording measures activity, stimulation tests functional influence, and imaging visualizes relevant structures or responses, allowing the method to serve multiple experimental designs.
Feeding Grasper Access links the physical organization of the feeding apparatus with investigation of nearby neural structures. That relationship allows researchers to examine circuits associated with feeding and the sensorimotor control underlying feeding actions. Because access can be targeted while surrounding anatomy is preserved, experiments may connect neural measurements or manipulations with the organization and function of feeding-related pathways.
When the preparation permits natural feeding behavior to continue, researchers can study neural activity or responses in a more behaviorally relevant setting. Preserving that behavior helps relate experimental measurements to actual sensorimotor control rather than to an isolated anatomical structure alone. The approach therefore supports investigations that connect targeted neural access with the functioning of feeding circuits during behavior.
