Such probes have an exceptionally durable structure that is also highly customizable. Brain Slice Multielectrode Arrays are available in linear, stereotrode or tetrode configurations and they are built into a stainless steel tube to provide support for accurate acute research.
The recording sites are placed on the bottom side of a Stainless Steel, “hockey stick” cone with a choice of 4, 8, 16, 24 or 32 electrode channels in a length up to 200mm. 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.
