This seminar will offer a basic account of event-related potentials for those who have little familiarity with them. It will cover how the ERP is obtained from the EEG, the assumptions underlying its derivation, and the problems involved in its extraction, but will presume a reasonable understanding of the EEG and how it derives from the electrical potentials of neurones. The seminar will review the major ERP components, their scalp distribution and the psychological functions they index, and provide a discussion of a number of the issues and techniques related to component identification from the ERP waveform. Issues and techniques relating to localising ERP components in the brain are also addressed.
Cardiac issues seen in monitoring channels (PVC, PAT, couplets... and Q-T interval elongation and sudden death). EOG and frontal lobe function (frontal eye fields) EMG chronic levels (headaches, TMJ, peripheral tension in over-arousal) CNS over-arousal and Electrodermal/thermal (myo-epithelial cells and sweat glands).
