Touchscreen Operant Chamber
Class of 2020
Peiyu is a big fan of coffee, science and rat.

An operant chamber is a common laboratory apparatus in the field of behavioral psychology and neuroscience that is used in experiments with animals—typically rats and mice. A touchscreen operant chamber is similar to a traditional chamber, but the lever-system is replaced by a touchscreen-microcomputer system. Touchscreen operant chambers are more flexible and make more complex tasks possible—such as a Sustained Attention Task, Working Memory Task and Visual Discrimination Task. 

A commercially available, single touchscreen chamber costs $7,055.00 (without the operating interface, $5,910.00, or software, $2,595.0). We don't have on in SLU, the goal of this project was build a cheap chamber based on Raspberry Pi (a cheap small single-board computer) and 3D print.
