Susann BoretiusIn many deeply anesthetized and comatose states, the brain’s electroencephalographic (EEG) signal alternates between bursts of higher amplitudes and periods of suppressed activity. The origin of this burst-suppression pattern and its distribution across the brain are subject of ongoing discussions. Burst-suppression has been traditionally viewed as a homogenous oscillation across the entire cortex but more recent findings have demonstrated considerable spatial variation in its origin and propagation. Because of differences in data acquisition methods and animal species, previous studies have not converged on how burst-suppression is distributed across brain regions. Most importantly, it is questionable whether the involvement of all or of specific brain regions in burst suppression is a universal phenomenon across mammalian brains or whether the spatial distribution differs across species. Answering this question may give us interesting hints on the evolution of brain functions.
