Course Overview
Building on a foundation of electrical safety, students learn the electrical and magnetic interactions underlying the technology and methods employed routinely in electroneurophysiology. Direct current and alternating current circuits are introduced, including the concepts of impedance of resistors and capacitors and their use as simple circuit filters. The oscilloscope, used as a method for visualizing waveforms and the parallel with digital EEG trace recordings is highlighted. Differential amplifier operation and the minimum acceptable specifications for their use in ENPY are explored along with digitization, sample rates, and the Nyquist limit. The scalp electrode is modeled and its relationship to the low pass AC filter. Additionally, students learn about magnetism and the principles of magnetic induction and its application to magneto-encephalography, electromagnetic waves, basic definitions of photometry in the context of photic stimulation used in electroneurophysiology, and the CAET photic stimulation guidelines are also introduced. This course will be a mixture of lectures, and tutorials. Assessment includes a range of assignments and examinations.

Learning Outcomes
Upon successful completion of this course, the student will be able to:
- Analyze simple DC and AC circuits, including calculating AC impedance of series R-C circuits.
- Explain the operation of simple low- and high-pass circuits made from R-C circuits, including determining the 3dB frequency and the phase shift associated with the filtered signals.
- Interpret the specifications associated with the differential amplifiers used in EEG systems in comparison to the CAET guidelines.
- Explain the concepts of digitization rate, bit depth, and the Nyquist limit as applied to electroneurophysiology.
- Describe the basic physical model of scalp electrodes and record AC waveforms using an oscilloscope.
- State the principle of magnetic induction, and calculate the EMF induced in a loop of wire due to the change in magnetic flux through the loop.
- Discuss how magnetic induction is used in magneto-encephalography.
- State the differences between photometry and radiometry, luminous flux and radiant power, and irradiance and illuminance.
- Estimate the illuminance of a light source and explain how this varies with the distance from the source to an object and with viewing angle.
- Apply the photometric quantities to interpret the CAET guidelines for the photic stimulation in electroneurophysiology.
