This article explores the concept of the equivalent dipole and its significance in neurophysiological studies, particularly in understanding thalamo-cortical fibers. It discusses differential recording methods such as F3, F3-F4, and F4, which are vital in recording event-related potentials (ERPs) in EEG studies. Additionally, the article covers the basics of signal segmentation and averaging in EEG stimuli analysis, providing insights into the intricacies of neuropsychopathology and its implications for clinical practice.
