Behavioral assays provide powerful tools for understanding neuronal function. Here we present several protocols for quantifying predatory feeding behavior found in the model nematode Pristionchus pacificus and its relatives. Additionally, we provide methods for analyzing predatory feeding adaptations including mouth structures and teeth.

This video describes the taste preference assay, a behavioral method used to measure attraction or avoidance towards colored solutions that taste differently by assessing the fly's abdominal coloration after ingestion of the preferred substance. The featured protocol demonstrates the procedure used to measure flies' preference towards solutions of varying sucrose concentrations.

The fruit fly, Drosophila melanogaster, extends its proboscis for feeding, responding to a sugar stimulus from its proboscis or tarsus. I have combined observations of the proboscis extension response (PER) with a calcium imaging technique, allowing us to monitor the activity of neurons in the brain, simultaneously with behavioral observation.

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.
FAQs
Ghrelin and leptin provide peripheral signals about internal energy status to neural circuits that regulate appetite. Their information is integrated with hypothalamic processing rather than acting in isolation, allowing physiological state to influence food seeking and satiety. This hormone-circuit interaction helps explain why feeding can change as the body’s energy requirements change.
The arcuate nucleus is an important hypothalamic component of the neural pathways that regulate feeding. It helps connect information about peripheral energy status with behavioral outputs, including motivation to seek food and signals associated with stopping consumption. Studying this region therefore links physiological regulation with observable changes in eating.
The mesolimbic dopamine system contributes to the reward-related and motivational aspects of feeding behavior. It helps food-related cues influence the drive to seek and consume food, complementing hypothalamic regulation of energy balance. This interaction shows why eating is shaped not only by physiological need, but also by the rewarding significance of food.
Sensory signals provide information about food-related cues that can interact with internal energy signals and neural reward pathways. Their integration can increase motivation to seek food or contribute to the transition toward stopping consumption. This mechanism helps explain how feeding behavior reflects both the body’s physiological state and the surrounding food-related context.
Research on feeding behavior examines how hypothalamic circuits, reward pathways, sensory signals, and peripheral hormones combine to regulate appetite and consumption. The resulting neural perspective helps investigators connect changes in eating with energy balance and survival. It also provides a framework for studying obesity, eating disorders, and metabolic disease.
Feeding behavior research can clarify how disrupted interactions among energy-status signals, hypothalamic circuits, reward pathways, and satiety processes affect eating. These mechanisms are relevant to obesity and metabolic disease because they connect neural regulation with physiological control of consumption. Understanding those links supports research into how abnormal feeding patterns arise.
By identifying how neural circuits and peripheral hormones influence food seeking, motivation, and satiety, neuroscience research can highlight regulatory processes that may be relevant to therapeutic development. The goal is not simply to describe eating patterns, but to connect behavioral outcomes with mechanisms that could guide research on obesity, eating disorders, and metabolic disease.
