embedded operant control system
starboard is a low-cost, modular, open-source and open-hardware system for operant behavioral experiments. You can control a range of input and output devices for presenting stimuli, detecting responses, and providing food rewards. The current implementation consists of a Beaglebone Black and a custom expansion card. Control software uses a modern, event-driven state machine framework and supports several basic training and test paradigms out of the box. Additional paradigms can be configured by specifying different state transition networks.
starboard has been used in the Meliza lab for experiments since summer 2014. Based on our experience, we are developing a B revision that emphasizes a more modular design that includes:
A repository with schematics, PCB layouts, and other information needed to construct your own starboard is hosted at melizalab/starboard. You can order PCBs from OSHPark for the cape and the LED breakout.
Beaglebones running decide can be connected to a host computer running an http-based database application, django-decide-host, implemented in the Django framework. Trials are logged to a persistent, centralized database with a REST-based API that can be easily searched by subject, controller, experiment, and many other variables.
