The Brain Slice Multielectrode Arrays are expertly handcrafted and made to order with many finished options available. These probes are bent at 120°, like a hockey stick, to effectively record the neural activity from the surface of a brain slice. The recording electrode sites are placed on the bottom side of the „hockey stick”.
These multielectrode arrays are available in single, stereotrode and tetrode configurations, each with a choice of 4, 8, 16, 24, 32 channels. Electrode sites are numbered from connector to tip. Spacing is customizable, however 100μm is typical.
Optional fluid delivery channels for precise drug delivery or fiber optic lines for optogenetic stimulation intermixed within the recording sites are available.
The platinum/iridium electrode recording sites are available in 15, 20, 25 and 40µm diameter options. The small electrode site diameter (15µm) enables effective single-unit recording, coupled with low impedance for a better signal-to-noise ratio. The larger diameter sites are more suitable for field potential recordings.
These probes are robust, which is due in part to their stainless steel construction. The most commonly used steel tube diameter is 260um, but it is customizable as well.
