Abstract

The invention relates to an electrode arrangement and a measuring device for measuring the action flow and/or the action potential of an electrically active tissue. The aim of the invention is to provide a simple and economically producible electrode for measuring action flows and/or action potentials in electrically active tissues (preferably the stapedius muscle tissue), ensuring that the electrode is fixed securely, but reversibly, in the muscle tissue and that the muscle tissue is disturbed as little as possible. The electrode arrangement according to the invention comprises a first electrode (2) and a fixing element (3), the first electrode (2) being connected to a first, long electrical line (4) and consisting of a long base body (6) comprising a first end (7) and a second end (8). The first electrical line (4) is connected to the base body (6) in the region of the second end (8) thereof, and means are provided for reversibly fixing the fixing element (3) to the first electrode (2).
