High-Density EEG: Thin-film Grid Electrodes

NeuroNexus EEG probes are advanced, ultra-flexible surface grids specifically designed for precise electroencephalography (EEG) applications. Fabricated using proprietary polymer MEMS technology, these probes conform seamlessly to the skull surface, enhancing comfort and data accuracy during neural recordings.

Key Advantages:

• Flexible and Durable: Polymer MEMS fabrication ensures the EEG probes conform gently and accurately to the skull.
• Optimized Recording Quality: Ideal for stable EEG recordings over long periods, including exploratory behaviors and REM sleep studies.
• Stable Long-term Performance: High durability, maintaining functionality over months of continuous recordings.

Technical Specifications:

• Electrode Material: Platinum
• Substrate Technology: Polyimide MEMS
• Array Thickness: 20 μm

• Cable Length: 10 mm

  Channel Count:

  • 30-channel configuration (specifically optimized for mouse EEG)
  • Standard 32-channel configurations for other designs
  • Custom configurations available upon request

Available Package Options:

• H32, HC32, HZ32, X3-H32
• Custom designs available to meet specific experimental needs

Applications:

EEG grids allow assessment natural brain rhythms such as exploratory and REM theta (4-12 Hz) during periods free of epileptiform activities.
