Limbic spindles: genuine cerebral activity or artifact?
A periodic spindling activity recorded in clinical EEG laboratories from nasopharyngeal (NP) leads has been interpreted as expression of genuine cerebral rhythms originating in the limbic system. Evidence is here presented to suggest that such activity is indeed an artifact. Genuine spindling occasionally occurs in NP leads but this is intimately related to sleep spindles occurring also in other surface electrodes.
