摘要：

A method is described by which a single shaft multiwire microelectrode can be fabricated efficiently. The resulting electrode can be attached to a commercial microdrive and used for single neuronal unit recording from one or more tracks in deep brain structures of anesthetized or awake animals. The electrode consists of a 30 gauge stainless steel cannula through which multiple strands of 13 μm insulated tungsten microwires are threaded. At the electrode tip the wires protude 3-4 mm from the cannula and are cut individually at suitable offsets. The tip is stabilized and fixed to the cannula with cyanoacrylate. At the base of the electrode the wires are threaded through flexible plastic tubing that provides strain relief and are glued to individual pins of a miniature connector that plugs into a field effect transistor (FET) voltage follower. Good single unit recordings have been obtained routinely from the basal ganglia of awake, behaving monkeys with this electrode. © 1990.
