This is a simple and inexpensive Arduino based system for recording behavior intraoperatively. As demonstrated, a patient undergoing Deep Brain Stimulation (DBS) (recording and stimulation) can be asked to discriminate and move to declare a choice between two audio frequency presentations. The movements of the patient can be monitored with this simple and inexpensive Arduino based system and a Wii Nunchuck. This Nunchuck allows the user to move a joystick with their thumbs AND includes a 3-axis accelerometer (perfect for recording tremors!). The movement of the thumb can be restricted with a 3D printed part (forcing the choice to be left or right), and the given MATLAB code will help you interpret your results.
