Experimental study on origin of cerebral bioelectric rhythm

An attempt is made to determine the origin of the biological electric signals of the cerebral cortex in a certain sense and to uncover the different contributions of the midportion of the thalamus, the gigantocellular tegmental fields of the midbrain, the locus caeruleus of the pons, and the raphe of the medulla oblongata under the cortex in the formation of the basic frequency of the cerebral cortex. Using the analysis of the square coherence spectrum, it is found that the gigantocellular tegmental fields provide higher frequency rhythms that belong to exciting bands, and the locus caeruleus and the raphe provide lower frequency rhythms that belong to resting bands
