Triangle BioSystems International has developed a 90-day implantable neural recording headstage system that allows researchers to continuously and simultaneously obtain biopotential data from up to 5-32 electrodes to an external receiver in real time. No longer do experiments have to be constrained by head mounted or wired test subjects to the recording system.
The complete system is comprised of an implantable inductively powered wireless headstage transmitter, RF signal receiver/baseband demodulator, power supply and a silicone electrode connection kit. With an effective range of 1 meter, this system provides a wireless connection between the implanted electrodes to the data acquisition recording system.
This implantable headstage unit is implanted in a rat’s peritoneal cavity using a minimally invasive surgical procedure. Additionally, this headstage can be used concurrently with our stimulation, tethered or multiplexed neural recording headstages. This system utilizes TBSI’s custom ASIC technology and packaging, wireless powering and proprietary radio design to provide reliable functionality in an implantable package that is both small and light weight. This design includes the neural preamplifier circuitry to create an extremely compact and powerful transmitter with high data rate and band-width.
The complete system is comprised of a wireless headstage transmitter with an integrated rechargeable battery, RF signal receiver/baseband demodulator, power supply, and basic interfacing cables.

Benefits and Advantages:
Recordings registered and/or stimulation delivered in a manner that is as close as possible to natural behavior
Ideal solution for recording and stimulation both in the cortical and peripheral nervous system.
Focus on one or multiple areas with spike-bandwidth on every channel up to 32 channels
Non-stop recording for long duration unsupervised experiments and high-throughput
Absence of signal contamination and lack of behavioral distraction due to tether movement.
Save costs (typically 5k USD per unit) and labor required to manually supervise tethered animals
Fast setup time and save costs on shielding and noise troubleshooting
Up to 3 wireless recording systems and 16 stim systems simultaneously in open field, >3 record systems possible in operant chambers with radio frequency shielding.
Connect directly to wide variety of electrodes for low-profile, highly robust chronic recording systems.
