Electrical Stim System



This system does double-duty in your lab. The RZ5D Processor, SIM Subject Interface Module, and ACO32 motorized commutator serve to acquire, process and analyze neural spikes from awake, behaving subjects. Use it to receive real-time updates from your behavioral control boxes (such as Med Associates, Lafayette, and Coulbourn) and smoothly integrate neural and behavioral data in a single data file. All events are timestamped and recorded for easy offline analysis.

The addition of the Subject Interface supports electrical stimulation and closed loop protocols. The RZ5Ds many I/O options give you the flexibility to trigger stimulation based on external events or control behavioral devices such as pellet feeders, liquid dispensers, or shockers. This system delivers the full benefit of the System 3 line of processors.
