[The electrophysiological and ultrastructural aspects of the effect of increased oxygen pressure on the sensorimotor cortex of rats].
Stay of the rats in barochamber under 0.3 MPa oxygen during 2 hrs induced separate sharp waves with no generalisation, the electron microscopic changes expressing activation of compensatory-adaptive processes. The generalisation of seizure activity over the cortex at 0.7 MPa oxygen affects a part of neuronal pool due, probably, to irreversible changes in inhibitory axosomatic synapses.
