Which electrode can be used to pick up signals from individual fibers

1.	Which electrode can be used to pick up signals from individual fibers of muscle tissues?(a) biopolar needle electrode(b) concentric core needle electrode(c) multi-element needle electrode(d) monopolar needle electrodeI got this question during a job interview.This interesting question is from Electrodes for EMG in chapter Bioelectric Signal and Electrodes of Biomedical Instrumentation
Answer» Correct OPTION is (c) multi-element needle electrode Easiest explanation: Multi-element needle electrodes are used to pick up the signals from individual fibers of muscle TISSUE. Special NEEDLES are available USING 25-micron diameter electrode surfaces. They have up to 14 pickup surfaces down the side of one needle.
