Emotion in man as Tested by the Delta Index of the Electroencephalogram: II. Simultaneous Records from Cortex and from a Region Near the Hypothalamus

Electroencephalography and physiological psychology: evaluation and statement of problem.

“…The results clearly indicated that, in both groups, delta frequencies were a response to such stimuli and that "emotional behavior" followed the delta frequencies. Further work demonstrated that the cortical changes were apparently a function of subcortical (hypothalamic) mechanisms (29).…”

Enzyme kinetics and the dynamics of behavior.

“…While in our study of activation energies of brain waves in man we recorded cortical electroencephalograms, there is evidence from several sources including our own studies indicating that the circuits conducting these waves pass through the hypothalamus and that the hypothalamus may actually be the rate determining center for the waves (17,18,30,31,21). For example, figure 8 from a former study of ours shows the similarity of waves recorded from the occipital cortex and simultaneously from a lead in the roof of the pharynx near the hypothalamus.…”

“…The upper tracings of C and E are from the occiput . Note similarities of patterns in a given individual from cortical and "hypothalamic" leads (17).…”

Evoked Brain Activity and Personnel Performance

“…Research has also demonstrated that EEC and stimulus-locked EEG records (EP) are very sensitive to individual differences (Berkhout Sc Walter, 1968;Brazier, 1962;Buchsbaum & Pfefferbaum, 1971;Callaway, 1975;Henry, 19^1a, b;Lewis, 1983a;Uttal & Cook, 196^;Werre & Smith, 1964). Early research relating more variable, state-like attributes (e.g., anxiety arousal) to psychological aspects were described by Travis (1937), Travis and Egan (1938), Hoagland, Cameron, Rubin, and Tegelberg (1938), Knott (1938), and Hadley (19^10, 1941).…”
