EEG Surface Grids

Designed for mouse and rat skulls, NeuroNexus EEG grids are ultra-flexible surface grids optimized for electroencephalography. Choose from reticular grid layouts, or functional layouts with more recording resolution over key cortical areas.

  • Flexible and durable – Fabricated with our polymer MEMS technology, our EEG probes easily conform to the skull. Use a drop of water to adhere the probe to the skull.
  • Stable – High-quality EEG recordings have been obtained over months.
  • Optimized array designs – Select from a variety of EEG array designs featuring different recording site placements, for different applications or animal models.

“Recordings with the multi-site grid were stable over periods of months (up to 3 months were tested without a significant reduction of signal quality). Over the course of epileptogenesis, seizures and other types of large amplitude interictal discharges were easily localized with the EEG grid.”

  • H-Series is a hybrid package introducing a flexible ribbon between the EEG grid and connector PCB to allow flexible positioning of the connector on the head.
    • H32 uses one Omnetics NPD36 connector
    • HC32 uses two Omnetics NPD18 connectors
    • X3-H32 uses 32ch EIB connector
