NeuroSnap A8

The NeuroSnap A8 Headstage is optimized for concurrent neurophysiology research during clinical monitoring in EMUs. The device achieves stable, low-noise single unit recordings by digitizing the signals on board. Its compact, lightweight, and robust design fits easily into headwraps, enhancing comfort without sacrificing data integrity in demanding clinical environments.

Features

The Neurosnap A8 is a compact heastage that boasts greater signal quality, comfort, durability, and ease of use compared to previous models.

Onboard Digitization

An on-board ASIC chip digitizes signals close to the source, dramatically reducing noise and enhancing signal clarity.

Lightweight and Compact

Designed for patient comfort, the A8 Headstage weighs only 1oz and fits unobtrusively under headwraps for extended use in sub-chronic studies.

Seamless System Integration

Acquires microelectrode data on the NeuroPort system, making it a single tool for comprehensive online, and closed loop neuroscience experiments.

Enhanced Durability

Built to withstand the physical demands of continuous use in the patient headwrap and withstand common cleaning agents

Investigational Use

ISO-13485 and IEC 60601 Compliant, NeuroSnap is ready for clinical research in IRB/IDE approved protocols.

Supported Electrodes and Connectors

Each NeuroSnap A8 records from up to four AdTech 9-Contact Micro-Wire Bundles, the industry leading Behnke Fried microelectrodes.

A Lightweight and Durable Design

Engineered for sub-chronic and acute recording, our NeuroSnap headstages combine a lightweight profile with robust construction. Weighing just 1.9 oz (53.86g), 75% lighter than Cabrio 16-channel adapters, it fits unobtrusively under the patient’s headwrap and ensures maximum comfort during extended clinical use. Its compact design does not compromise on resilience however, ensuring reliable performance during severe seizures.

Digital Precision in Neural Signal Transmission

On-board signal digitization allows transmission of 32 channels of high resolution data over a single, thin cable. Cable length no longer affects signal quality.

Impedance Measurement

The NeuroSnap headstages measure micro-electrode impedances,covering a range 5kOhm – 1MOhm. This capability allows measurement and assessment of electrode quality and status over the course of the implant.
