Sciatic nerve recording. A: anatomical illustration of sciatic nerve branches seen under the microscope. The tibial nerve (black) has three branches supplying the triceps surae muscle. The recording electrode (R) is inserted into the tibial nerve just before it enters the muscle. The stimulating electrode is situated 2 cm away from the recording electrode. B: Spontaneous activity from the tibial nerve that was correlated with muscle twitches confirming that the location of the recording (R) electrode is in the nerve bundle that innervates the triceps surae muscle. S - bipolar, stimulating electrode
