Cortical and subcortical electrical activity during the development of hypoxia from blood loss

It was shown previously that in some cases during the development of hypoxia polymorphic Δ waves are replaced by synchronous standardized waves, also in the Δ band, which have been called standardized slow complexes (SSC). In the present investigation discharges of the neuron pool were observed during SSC in the caudate nucleus, lateral and medial thalamus, hypothalamus, hippocampus, amygdaloid nucleus, and mesencephalic reticular formation. The highest firing rate of the neurons correlated (P<0.01) with the second half of the negative phase of SSC. Bursts of discharges of the neuron pool during SSC indicate that it reflects physiological processes taking place in these structures.
