These probes are designed for acute application in medium to large subjects, such as primates and they are available in linear, stereotrode or tetrode configurations. Deep Brain Probes have a durable structure that is also highly customizable. They allow either superficial or deep brain penetration.

Deep Brain Probes have multiple recording sites in a configuration up to 32 electrode channels. They come with either a conical or sharpened tip, from which the latter has the benefit of easy dural penetration. It could be integrated into a Stainless Steel guide tube, which may offer an easier and more precise implantation.
The recording sites are placed on the side of a symmetric, epoxy cone with a choice of 4, 8, 16, 24 or 32 electrode channels in a length up to 150mm. These Platinum/Iridium recording sites are available in 15, 20, 25 and 40μm diameter options. The smallest diameter of 15μm allows effective single-unit recording, and complemented with low impedance such probes have a better signal-to-noise ratio (SNR). Larger diameter probes are more suitable for field potential recordings. Epoxy filled polyimide tubing acts as a lead, which connects the recording array to the connector.
