Nadiya Abramyuk Bio205 LAB Instructor: Faiza Peetz Electrodermal Activity & The Polygraph Introduction Due to the difference in electrical pressure, electricity flows through the circuit from the beginning of the circuit to the end. A current, which is a simple circuit of direct electrical flow of electricity, has a correlation between the electromotive force which causes electrical currents, and the magnitude of the current. This relationship between electromotive forces and the magnitude of the current is known as Ohm’s Law and it implies that if a constant current is applied across a resistance, it will create a voltage change exact to the resistance change due to the changes in the resistance. Areas like the fingers and palm of a hand shows several forms of bioelectric phenomena, including the feer. Galvanic skin resistance also known as GSR is when a weak electric current is applied to two electrodes which records electrical resistance between them. Depending on the subjects emotional state, result will vary. This experiment will indicate how to apply principles of Ohm’s Law and record changes in the electrical resistance of the skin. Materials - BIOPAC disposable vinyl electrodes (EL503) – 3 electrodes per Subject BIOPAC Electrode lead set (SS2L) - BIOPAC Electrode gel (GEL1) - BIOPAC GSR transducer (SS3LA or SS57L) - BIOPAC Respiration transducer (SS5LB or older SS5LA or SS5L) - BIOPAC PAPER1 or nine sheets of different colored paper. Recommended: 8-1/2”x 11” sheets of: white, black, green, red, blue, yellow, orange, brown, purple. - Computer system: PC running Windows XP ® Memory requirements: The Biopac Student Lab application needs to have at least 4MB of RAM available for its needs. This is 4MB above and

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
