Previous experiments on dogs showed that in several cases, along with the development of hypoxia, polymorphous delta-waves changed into synchronous oscillations, also of delta range, the so-called standard slow complexes (SSC). The new experimental data showed discharges of neuronal pool during SSC to be present in the caudate nucleus, lateral and medial thalamus, hypothalamus, hypocampus, n. amygdale, and mesencephalic reticular formation. The most frequent neuronal pulse activity was connected with the second half of the SSC negative phase (P is less than 0.01). Discharge flashes of the neuronal pool during the SSC indicated that SSC reflected the physiological processes occurring in these structures.
