Site Layouts

Below are examples of different types of microelectrode array tips you can find in our catalog.

Site Layouts2 1

Linear microelectrode arrays are the foundation for multi-channel 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 microelectrode arrays fit the widest range of applications.

Site Layouts2 2

Edge sites are similar to the Linear layout, but the microelectrode sites are strategically positioned at the edge of the substrate.

Site Layouts2 3

A tetrode is an arrangement of four microelectrode sites placed close together, allowing for high-quality cell discrimination in recordings.

Site Layouts2 6-02

Polytrode microelectrode site layouts come in two variations: Poly2 (two columns of sites), and Poly3 (three columns of sites, shown above). They have a mix of linear and tetrode benefits, with sites close enough together to allow a degree of multiple representation across different sites, while sampling a larger space.

Site Layouts2 5

Multi-shank microelectrode arrays provide a two-dimensional representation of the brain. By controlling shank and site spacing, a more detailed understanding of a larger space in the brain can be obtained. Some multi-shank designs incorporate tetrode and polytrode site arrangements.
