Congratulations to Dr. Giridhar Kalamangalam on the publication of “Montages for Noninvasive EEG Recording,” which was published in the Journal of Clinical Neurophysiol this month.
Identifying the localization, distribution, and polarity of waveforms are the prime goals of clinical scalp EEG analysis. Appropriate choices of bipolar and referential montages are keys to emphasizing the diagnostic features of interest, and demand some understanding of the spatiotemporal physical behavior of the underlying neuronal generators. Several examples drawn
from canonical epilepsy syndromes are used to illustrate this general message.
