TL;DR
Standardized EEG recordings were obtained from 64 well matched, identical and fraternal twins and measures made of the spontaneous EEG and the alpha attenuation and the averaged evoked responses showed a tendency towards consistency and long-term stability within the same individual.

The possibility is considered that a background of maintained activity within this ascending brain stem activating system may account for wakefulness, while reduction of its activity either naturally, by barbiturates, or by experimental injury and disease, may respectively precipitate normal sleep, contribute to anesthesia or produce pathological somnolence.

A method of estimating the probability of dizygotic and monozygotic twin pairs is described and formulae for obtaining these tables for the P, Lutheran, Kell, Duffy, Kidd and non‐secretor (or Lewis) systems are given.

The human brain generates electrical potentials strong enough to be detected through the intact skull, and a record of these potentials is analogous to the familiar electrocardiogram and furnishes a convenient external index of the activity of a hidden organ.

Cerebral responses to stimulation of the median nerve were recorded in 89 healthy subjects, aged 15 to 80 years, and relationships between response characteristics, age, sex, and Maudsley Personality Inventory variables were determined.

In a number of instances an identical twin's visually evoked response was more like that of his twin sib than like another of his own recorded at a different time.

Computer analysis of visually evoked responses in seven subjects over several weeks indicated stability of the response of each individual, with reliable intra-individual correlations, however, inter-individual differences were large.

Variability of the individual brain wave potentials comprising an auditory averaged evoked potential (AEP) is greater for schizophrenic than for normal subjects and this increase of AEP variability in schizophrenic patients reflects response variability and is not principally the result of increased background EEG variability.

The waking alpha rhythms from one MZ twin resembled those from the other as closely as the record of the same person on successive recordings as evidence of the hereditary nature of any given trait.

Cortical responses evoked by sensory stimulation in recordings taken from the human scalp are studied with the aim of determining whether psychiatric illness is associated with measurable abnormalities in cortical reactivity.

Although all three patients showed cyclical mood changes, and each showed biochemical and EEG changes according to the mood, there was no pattern common to all three and there is no clear generalized relationship between the EEG, the mood and the biochemistry.

No significant correlation was found between any of these variables and extraversion or neuroticism as measured by the Maudsley Personality Inventory or the alpha index, mean alpha amplitude and the alpha blocking responses to serial paired flashes of light.

Subjects who were not psychiatric patients showed full recovery of responsiveness during the initial peak phase, whereas most of the psychiatric patients did not.

Comparison of amount of alpha activity for 3 sec preceding each stimulus indicated that the significant differences obtained between the groups were not due to differences or variations in background activity.

Clinical improvement in the schizophrenic patients was associated with a shift in the two-tone AER toward values seen in nonschizophrenics, and the clinically improved schizophrenics also demonstrated an increased amplitude of evoked response.

A specific pattern of the normal electroencephalogram, which is characterized by unusually regular, high voltaged α-waves reaching up to the frontal cortex is analyzed as to its mode of inheritance, as marriages between persons with the EEG-trait were more frequent than expected.

Present data would appear to indicate that the alpha blocking responses reported are more likely manifestations of the reappearance of the orienting response to a novel stimulus, rather than true conditioning.

Comparison of the intraclass correlation coefficients for each of the recorded AAR parameters between the two twin series and a constructed series of genetically unrelated individuals indicated that individual differences in the variables measured were significantly influenced by heredity.
