The effects of Nembutal on the intracerebellar EEG activity revealed by spectral and fractal analysis

摘要

Paper description:Studies of the effects of anesthetics on functional brain networks are essential to understand changes in brain bioelectrical activity in health and disease.Using spectral and fractal analysis, we recorded the electroencephalographic (EEG) activity at different layers of the cerebellum during nembutal anesthesia.Nembutal induced an increase in delta (0.1-4.0 Hz) and a decrease in theta (4.1-8.0 Hz) EEG frequency ranges, and an increase in the value of Higuchi’s fractal dimension in the cerebellar layers.This study indicates that spectral and fractal analysis can be used complementarily for measuring anesthesia-induced intra-cerebellar EEG dynamics.
