DOI: 10.1007/s00521-020-04897-5
Abstract: Systemic low-frequency oscillations (sLFOs) are non-neuronal oscillations at 0.01–0.15 Hz. These sLFOs travel through the entire body and the brain with symmetrical (across the midline of the body) and highly predictable delays, where they can be… read more here.

DOI: 10.1016/j.bbe.2020.07.008
Abstract: Abstract The neural baroreflex, which regulates mean arterial pressure (MAP) via the action of the brain, consists of baroreceptors which measure MAP, and actuators that can produce a change in MAP, such as the heart… read more here.

DOI: 10.1016/j.clinph.2018.10.016
Abstract: OBJECTIVE High frequency oscillations (HFO) between 80-500 Hz are markers of epileptic areas in intracranial and maybe also scalp EEG. We investigate simultaneous recordings of scalp and intracranial EEG and hypothesize that scalp HFOs provide important… read more here.

DOI: 10.1016/j.nbd.2018.12.016
Abstract: High-pass filtering (> 80 Hz) of EEG signals has enabled neuroscientists to analyze high-frequency oscillations (HFOs; i.e., ripples: 80-200 Hz and fast ripples: 250-500 Hz) in epileptic patients presenting with focal seizures and in animal models mimicking this… read more here.

DOI: 10.1038/s41598-021-85827-w
Abstract: To achieve seizure freedom, epilepsy surgery requires the complete resection of the epileptogenic brain tissue. In intraoperative electrocorticography (ECoG) recordings, high frequency oscillations (HFOs) generated by epileptogenic tissue can be used to tailor the resection… read more here.
