Abstract

An improvement to tungsten-in-glass microelectrode has been made which requires to special skills. It involves the introduction of a gel solution into the glass micropipette which surrounds and binds the tungsten wire along its full length. A significant damping of microphonic effects is produced and a good fit between tungsten and glass near their tips becomes less critical for success. The electrode was found to be very stable over long recording sessions.
