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.
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.
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.
