Fundamentals of ERP Recording
Overview: This module is designed to introduce students to electroencephalography equipment. Can be combined with a lab tour and/or select slides from Module 7.
Topics Covered:
- The parts and functions of EEG and ERP systems
- Basics of electricity
- Types of electrodes (ground, reference, active, and electrooculogram)
- Common-mode rejection
- Electrode caps and standard configurations
Source of the EEG Waveform
Overview: This module is designed to provide students with a conceptual understanding of how the brain produces an EEG signal and the factors that influence the strength and polarity of the signal.
Topics Covered:
- Action potentials and post-synaptic potentials
- How post-synaptic potentials create neural dipoles
- How dipoles summate to create a scalp distribution
- How the EEG waveform tracks changes in scalp voltage over time
- Factors that influence the strength and polarity of the EEG waveform
