Ključnе rеči: | rat brain;seizures;camphor essential oil | Dаtum izdаvаnjа: | 1-дец-2009 | Čаsоpis: | General Physiology and Biophysics | Sažetak: | We investigated the rat brain activity in acute seizures evoked by camphor essential oil or its main constituent 1,8-cineole by wavelet (primarily) and fractal analysis. Experiments were performed on anesthetized animals before and after intraperitoneal camphor oil or cineole administration. The properties of frequency bands in pre-ictal, ictal and inter-ictal stages have been determined by wavelet analysis. The domination of δ frequency band was confirmed in obtained brain activities, which participate with ≈45% of mean relative wavelet energy (MRWE) in control signals and arise up to ≈76% MRWE in energy spectrum during the ictal stage (after drug administration). Other frequency bands decreased during ictal stage and arised in inter-ictal stage. There was a dose-dependent response of cineole effect: increase in cineole concentration leaded to the higher values of relative wavelet energy (RWE) of δ frequency band while there were slight changes of the mean fractal dimension (FD) values as a measure of system complexity. | URI: | https://open.uns.ac.rs/handle/123456789/13160 | ISSN: | 2315882 |
