MICROWIRE BRUSH ARRAY

Microwire Brush Array

The Microwire Brush Array [MBA] was developed in cooperation with Dr. David Leopold’s Laboratory at the National Institutes of Health. The design concept, which features a large number of microwires tightly bundled within a single Microfil tube, provides a unique approach for recording and/or stimulating small neural pools below the cortical surface. The Microwires are designed to separate and splay out as they are implanted.

The design concept allows a large variety of configurations to cater specifically to the researcher’s application and experimental protocol.

CHARACTERISTICS

  • Up to 128 individual microwires.
  • Multiple wires diameters may be specified within a single array.
  • Can be configured for either acute or chronic implantation.
  • May be re-used for acute applications.
  • Chronic designs feature a flexible silicone cable between the brush array and connector, allowing the array to move freely with the brain.
  • Brush Array designs are adaptable to a large number of connector types.
  • Overall length can be specified between 2.5 mm to 120 mm.
  • Shank diameter depends on the number and size of microwires selected.
