Feeding Experimentation Device version 3 (FED3): FED3 is a smart pellet dispensing device for home-cage training of mice in operant tasks.
We have 12 FED3 devices. FED3 is a wireless, battery-powered device designed for home-cage training of mice in operant tasks. Mice interact with FED3 through two nose-pokes and FED3 responds to the mice by delivering pellets, visual stimuli (lights), and auditory stimuli (tones). FED3 has an analog output that allows it to synchronize with and control external equipment such as optogenetic stimulation or fiber photometry recordings. FED3 can be programmed to assess food intake, motivation, and operant learning in mice.
