Protocol to study circadian food-anticipatory poking in mice using the feeding experimentation device version 3.

ABSTRACT: Food-anticipatory nose poking is a unique food-seeking behavior driven by the food-entrainable oscillator. Here, we present a protocol to record a novel food-seeking nose poking behavior in mice under temporally restricted feeding followed by food deprivation using the open-source feeding experimentation device version 3 (FED3). We describe steps for setting up the FED3 and cage, training, and habituation. We then detail procedures for setting up the schedule for time-restricted feeding and food deprivation and for generating ethograms from FED3 data. For complete details on the use and execution of this protocol, please refer to Ehichioya et al.¹.
