Brain Slice Multielectrode Arrays - BMA

Brain Slice Multielectrode Arrays have multiple recording sites in a configuration up to 32 electrode channels. These probes are bended at 45° to effectively record the neural activity from the surface of a brain slice.

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.

We can also build either capillaries or fibers into the Brain Slice Multielectrode Arrays for local drug delivery and optogenetical studies, respectively. The capillary fluid channel may need to be placed between the recording electrodes. Note that the minimum diameter of the probe may need to increase to accommodate these capabilities.

Multiple connector types are available for providing easy connection to your data acquisition system. It may also be possible to produce Brain Slice Multielectrode Arrays beyond the listed parameters to facilitate the most ideal setup for your research needs.
