ArduiPod Box

ArduiPod Box is a simple, comprehensive touchscreen-based operant conditioning chamber that utilizes an iPod Touch in conjunction with an Arduino microcontroller to present visual and auditory stimuli, record behavior in the form of nose-pokes or screen touches, and deliver liquid reward. In his 2014 paper, Oskar Pineño introduces ArduinoPod Box and demonstrates the use of the device in a visual discrimination task.

ArduiPod Box relies on an open-source iOS app named Shaping that can be downloaded for free at the iTunes store, as well as, on Dr. Pineno’s website. Detailed instructions for assembly of the ArduiPod Box are also detailed on the website. In addition, video demonstrating of ArduiPod can be found here.

Rodent Operant Bucket (ROBucket)

Horizontal Figure 1-01The Rodent Operant Bucket (ROBucket), designed by Dr. Alexxai Kravitz and Kavya Devarakonda of the Eating and Addiction Section, Diabetes Endocrinology and Obesity Branch, NIDDK, is an inexpensive and easily assembled open-source operant chamber, based on the Arduino microcontroller platform, that can be used to train mice to respond for a reward.

The apparatus contains two nose pokes, a drinking well, and a solenoid-controlled sucrose delivery system. The chamber can easily run magazine training, fixed ratio and progressive ratio training schedules, and can be programmed to run more complicated behavioral paradigms.

In their 2016 paper, “ROBucket: A low cost operant chamber based on the Arduino microcontroller,” Kavya Devarakonda, Katrina P. Nguyen, and Alexxai V. Kravitz validate ROBucket by demonstrating its application in an operant conditioning paradigm, as well as, detail the hardware comprising ROBucket, and the flexible software controlling it.

Further documentation of this device can be found on the NIDDK website, where Dr. Kravitz and his lab share ROBucket construction instructions, ROBucket design files, ROBucket source code, and 3D printing design files.
