Linear electrode arrays are the foundation for multichannel recordings. The laminar design allows for a longer area of coverage than a single tip site, and either facilitates or replaces the need for passage-type experiments. Linear electrode arrays fit the widest range of applications.
Edge sites are similar to the Linear layout, but electrode sites are strategically positioned at the edge of the substrate.
Tetrode is an arrangement of four electrode sites placed close together, allowing for high-quality cell discrimination in recordings.
Polytrode electrode site layouts come in two variations: Poly2 (two columns of sites), or Poly3 (three columns of sites). They have a mix of linear and tetrode beneﬁts, with sites close enough together to allow a degree of multiple representations across different sites while sampling a larger space.
Multi-shank electrode arrays provide a two-dimensional representation of the brain. By controlling shank and site spacing, a more detailed understanding can be obtained of a larger space in the brain. Some multi-shank designs incorporate tetrode and polytrode site arrangements.
