1.	What is the recording called in which voltage difference between an active electrode on scalp with respect to reference electrode at ear lobe or any other part of the body is recorded?(a) Unipolar(b) Bipolar(c) Monopolar(d) NonpolarThe question was posed to me in class test.My question is based upon Multi-Patient Telemetry topic in portion Biomedical Telemetry of Biomedical Instrumentation
Answer» CORRECT choice is (c) Monopolar The explanation: This type of recording is CALLED ‘monopolar’ recording. EEG may be recorded by picking up the voltage difference between an ACTIVE electrode on the scalp with respect to a reference electrode on the ear lobe or any other PART of the body.
