title: [Impact of hypoxia in different periods of prenatal ontogenesis on ECoG of rabbit fetus].
abstract: Sensitivity of ECoG of sensorimotor cortex of 28-day rabbit foetus in different periods (prefetal and fetal) of embryogenesis to hypoxia impact was studied. In the foetus subjected to hypoxia during prefetal period (8-18th days) in the spectrum of the general activity the increase of slow waves, occupying little portion of the spectrum, is noticed, while the main delta-rhythm has more clear pattern. At the same time, hypoxia, undertaken in the fetal period (18-28th days) does not have significant effect on ECoG indexes. On the basis of our own and literature data one can propose tha high sensitivity of ECoG to oxygen deficiency is due to low stability of the brain cortex itself and subcortical white matter to hypoxic inpairement in early embriogenesis.
