This protocol describes a standard intermittent-access two-bottle choice home cage drinking paradigm to model alcohol consumption in rats. In addition, it provides step-by-step instructions to augment the standard protocol with a DIY lick detection system that enables microstructural analysis of drinking behavior.

A binge-eating model was established in mice using intermittent access to M&M's (a highly palatable food made of fat and sugar). Mice with intermittent access to this high-fat, high-sugar food showed stress-like behaviors, increased caloric intake, and a preference for that food over standard chow compared to mice with continuous or no access to the food.

We present methods for fabrication of patterned microstructures of vertically aligned carbon nanotubes (CNTs), and their use as master molds for production of polymer microstructures with organized nanoscale surface texture. The CNT forests are densified by condensation of solvent onto the substrate, which significantly increases their packing density and enables self-directed formation of 3D shapes.
FAQs
Bout size reflects how much is consumed during an individual intake episode, whereas eating rate describes how quickly that episode unfolds. Examining both measures can help separate altered hunger or motivation from changes in meal termination. For example, a condition may change the amount consumed per bout, the speed of eating, or both, even when total intake appears similar.
The interval separating intake bouts adds a temporal dimension that total consumption cannot provide. Shorter or longer gaps may indicate changes in how feeding is organized across time, while bout duration and size show what happens within an episode. Together, these measures characterize the sequence of feeding behavior and help identify alterations in appetite regulation or satiety.
The method compares several features rather than relying on one intake value. Changes in bout size, duration, eating rate, and the spacing of bouts can produce different behavioral patterns. This multidimensional profile helps investigators evaluate whether an intervention is associated with meal termination, hunger, motivation, or another aspect of feeding organization, rather than assuming every intake reduction has the same cause.
A study records individual intake events over time and quantifies the characteristics of those events. Core measurements identified in this approach include bout size, bout duration, eating rate, and intervals between bouts. Organizing the observations in this way allows researchers to examine both the properties of each intake episode and the timing of feeding across the observation period.
Researchers use this approach when the scientific question concerns how feeding unfolds, not simply how much food or fluid is consumed. It is relevant when studying appetite regulation, obesity, metabolic disease, or the effects of medications and physiological interventions. The detailed pattern can reveal behavioral changes that a single total-intake measurement might conceal.
In medicine and behavioral neuroscience, the measurements provide behavioral evidence that can be related to underlying biological mechanisms. Investigators can compare intake patterns across physiological interventions, medications, or disease-related conditions and assess changes in hunger, satiety, motivation, or meal termination. This supports interpretation of feeding behavior in research on appetite regulation, obesity, and metabolic disease.
