The slave module connects directly to operant conditioning control systems such as those made by Coulbourn Instruments and TSE Systems . Additional bar-press or other types of modules can be designed upon request. The communications module can handle up to 4 inputs and 3 event outputs. Two NiCD AA-size rechargeable batteries power the master communications module for up to 3 days of continuous operation. The Swivelless Swivel constantly monitors the animal's rotational movement to drive the arm, and these signals can be monitored when this module is installed.
Rotational activity is monitored using an encoder on the rotating portion of the system.
Each revolution of the animal will produce 128 pulses. CW and CCW rotation are sent to two independent 5V TTL outputs. When a head mounting tether is used, subtle head movements can be monitored using a third TTL output which is derived from the Hall-effect sensor which is supported by the lever arm at the top of the tether. These systems are made to order and frequently require customization. Please contact Instech to discuss your application and request a quotation.
