Research papers with FED

The first version of the Feeding Experimentation Device (FED1) was created by Katrina Nguyen and colleagues in the Kravitz lab, and was released as an open-source design in 2016:
Feeding Experimentation Device (FED): A flexible open-source device for measuring feeding behavior

FED1 was used to collect data in the following publications:
Coordinated ramping of dorsal striatal pathways preceding food approach and consumption
Need-based prioritization of behavior
Defined Paraventricular Hypothalamic Populations Exhibit Differential Responses to Food Contingent on Caloric State

FED2 was an improved version of FED1 that was smaller and included a screen. This version was developed between 2017-2018 but was not widely used.

FED3 was a further improvement that added operant training capabilities to FED. FED3 was used in the following publications:
High-fat food biases hypothalamic and mesolimbic expression of consummatory drives
Deficits across multiple behavioral domains align with susceptibility to stress in 129S1/SvImJ mice
A Vagal-NTS Neural Pathway that Stimulates Feeding
Weight Loss After Obesity is Associated with Increased Food Motivation and Faster Weight Regain in Mice
Rodent Arena Tracker (RAT): A Machine Vision Rodent Tracking Camera and Closed Loop Control System
Central and peripheral GLP-1 systems independently and additively suppress eating
Ventral arkypallidal neurons modulate accumbal firing to promote reward consumption
A role for the locus coeruleus in the modulation of feeding
