Hippocampal barques and their manifestation as 14 & amp;6 Hz positive spikes during sleep

CONCLUSIONS: Hippocampal barques are predominant in NREM II and SWS, and tend to increase their presence during SWS. Their scalp manifestation as 14&6/sec positive spikes is confounded by wakefulness, REM and NREM I stages, and "masked" by the co-occurrence of NREM II and SWS slow waves, and overlapping reactive micro-arousal elements.SIGNIFICANCE: Our study highlighted the overnight profile of hippocampal barques, in relation to the respective profile of their scalp manifestation, the 14&6/sec positive spikes variant.PMID:38042011 | DOI:10.1016/j.clinph.2023.11.008
