| Description | Human brain cell assemblies fire electrical impulses up to very high frequencies, which limit is not yet known. Using advanced intracranial microEEG recordings in a cohort of epileptic patients, we newly identified short-lasting oscillations in frequencies between 2 and 8 kHz. These ultra fast oscillations were consistently and locally detected in epileptic hippocampi but were extremely rare in non-epileptic brain tissue. The discovered electrophysiological phenomena thus may reflect neuronal hyperexcitability. |
