With our W-Series recording system, you can obtain data from up to 126 neural electrodes without having to sacrifice form or function. Our custom single-ended ASIC amplifier design enables every channel to amply sample low frequency wave forms and spikes alike. Your test subjects will be free to move and behave naturally in the environment of your choosing, while you can rest assured that your data will be of the highest quality.
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.
Features:
• Wireless recording: 5-32 channels in mice, 5-128 channels in rats and larger species
• Wireless inductive powering option
• Unconstrained natural behavior with motion tracking (OptiMap software)
• No tether artifacts
• No need for cable commutators
• Minimal sensitivity to 50/60 Hz mains noise
• Multiple systems in parallel
• Plug and play with silicon probes
Benefits and Advantages:
• Focus on one or multiple areas with spike-bandwidth on every channel up to 128 channels
• Non-stop recording for long duration unsupervised experiments and high-throughput
• Easily study locomotion, sleep, social interaction, operant conditioning, and behavioral pharmacology/lesions
• 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 shielding
• Connect directly to silicon probes to create low-profile, highly robust chronic recording systems
