The firing-tools brain slice electrode is essentially a standard steel tubular electrode that is bent 45 degrees. Thus, it is suitable for draining action potentials from brain slices. This electrode is installed in a thin-walled steel tube, typically 185 microns in diameter. The lead points are made of platinum-iridium wire, the distance between which is determined by the researchers between 50 and 500 microns.
The drain points are secured with implant-grade epoxy resin and can be selected from 15 to 40 microns in diameter. The tip of the electrode is shaped like an injection needle at an angle of 15-30 degrees. In addition to the drain points, it is also possible to introduce a liquid channel or fiber optics, the menu item of which is located below.
• Steel needle: thin-walled stainless steel tube (ferromagnetic material!). Diameter: 185-360 microns.
• Lead points: platinum-iridium wire. Diameter: 15, 20, 25, 40 microns.
• Synthetic resin binder: implant grade epoxy resin.
• Connector: Omnetics, Precidip, etc. different types.
