Triangle BioSystems International presents a dual channelwireless neural stimulation system that allows researchers to generate and upload two separately customizable waveform patterns via a USB dongle transceiver. Alternatively, the two  channels can be combined to  achieve  an even larger  voltage  differential.  The  complete  system  is  comprised  of  a wireless stimulating headstage with integrated  battery,a  USB dongle transceiver and StimWare™pattern generation software.The StimWare™ software interface allows the user direct control over the details of the uploaded stimulation pattern,including three tiers of  nested patterns, on/off function and a manual pattern trigger option.

This small headstage unit can be quickly and easily mounted on an animal's head and, depending on the programmed signal frequency and amplitude, can provide up to weeks of wireless  stimulation before draining the battery completely. Additionally, this headstage can be used concurrently with our wireless, tethered or multiplexed neural recording headstages.
