Title Frequency analysis of EEG in rats during the preconvulsive period of O2 poisoning
Bibliographic information Oct. 1981, Vol.52, No.10, p.598-603. Illus. 46 ref.
Abstract The characteristics of preconvulsive electrocorticogram in awake, unrestrained rats exposed to 3, 4 and 5 atmospheres oxygen were determined. The time interval of rectified voltage of the individual Δ (0.5-4c/s), θ (4-8c/s), α (8-13c/s), β1 (13-20c/s), and β2 (20-30c/s) bands were plotted against time. An elevation in Δ and a temporary reduction in α activity before the onset of the first electrical discharge (FED) was observed. Continuous reduction in β1 and β2l frequency bands occurred during the entire pre-electrical discharge period. The activity of θ and α frequency bands was significantly elevated about 1min before the onset of FED, and of β1l and β2l during appearance of the FED. Pathological effects of hyperbaric oxygenation are discussed in relation to these changes.
