The V-probes are multi-use, multi-site linear electrodes, which are expertly handcrafted and made to order with many finished options available. The tip of the electrode is conical shaped to further minimize trauma to the brain tissue upon insertion. It also permits an electrode site to be placed closer to the tip of the neural probe.
These probes are robust, which is due in part to their stainless steel construction. The most commonly used steel tube diameter is 185µm, customizable between 185-360 microns. The platinum/iridium electrode recording sites are available in 15, 20, 25 and 40µm diameter options. Electrode sites are numbered from connector to tip.
These electrodes are available with a choice of 8, 16, 24, 32 or 64 channels. Inter-electrode spacing: 50μm, 75μm, 100μm, 150μm, or 200μm along length of probe.
Optional fluid delivery channels for precise drug delivery or fiber optic lines for optogenetic stimulation intermixed within the recording sites are available, but must be placed within the half of sites closest to the connector.
These probes along with U-Probes, S-Probes, K-probes and standard Thumbtack Probes with polyimide-epoxy composite shaft are exclusively sold worldwide (excluding Hungary) by Plexon Inc.
