The study found that electrocephaloelectral asymmetry in the resting state's forehead was related to different dimensions of the split trait.

Schizophrenia has positive symptoms, negative symptoms and cognitive impairment and other common symptoms, affecting about 1% of the world's population.
can also be observed in healthy individuals, but to a lesser extent, these characteristics are collectively referred to as schizophrenic personality traits.
study of schizophrenic personality traits is a way to better understand these symptoms, with the advantage that the results are not disturbed by factors such as common medications, course of illness, and hospitalization experiences in patients.
static encephalopathic electrical signals that record an individual's state of silence and relaxation, reflecting the inner and inherent patterns of activity in the brain, are the basis of various cognitive activities.
previous studies have found that people with schizophrenia have abnormal e-brain power during rest and cognitive tasks, especially the increase in the power of the right frontal leaf relative to the left frontal leaf.
asymmetry of the left and right foreheads is related to the different dimensions and severity of the patient's symptoms.
For example, in chronic patients with negative symptoms, a significant increase in the power of the right frontal loin relative to the left frontal loin gamma was observed, while in acute patients with positive symptoms, similar abnormal partialization was widespread in the theta, alpha, beta, and gamma bands.
Wang Kwai, Ph.D., And Yu Yanyang of the Mental Health Key Laboratory of the Institute of Psychology of the Chinese Academy of Sciences, etc. explored the association between the divisive personality traits of the general population and the e-brain asymmetry of the resting state, and whether the association had stability across time.
study used a split personality questionnaire to measure the split personality traits of 52 college students and recorded a five-minute static brain electricity.
to explore the stability of the cross-time, the subjects returned to the lab three months later to complete the same procedure.
the researchers calculated the total score of divisive personality traits and three dimensional scores in each measurement: cognitive-perceptic dimension, interpersonal dimension and unorthortic dimension.
EEDs use fast Fourier transformations to calculate the absolute power of the six bands of a single subject, delta, theta, alpha, beta1, beta2, and gamma, using the difference in power between the left frontal leaf electrode and the right frontal leaf electrode as an indicator of electroencephalic asymmetry.
results show that the total score of the split trait (r s.81, p slt; .01) and its three dimensions (r_values and .71, p_values and .01) have high span time stability;
the first measurement, the total score of the split trait is associated with beta2 (r s -.35, p slt; .05) and gamma (r s -.38, p slt; .01).
dimensions, this association exists mainly in the interpersonal dimension and the unothicial dimension (Figure 1).
second measurement three months later, the total score of the split trait was associated with the asymmetry of the forephedal theta band (r -.36, p -lt; .05) and the alpha band (r s .38, p .lt; .05).
sub-dimensionality, this association exists mainly in cognitive-percessive and unsociate dimensions (Figure 2).
addition, studies have found a negative correlation between the asymmetry of the forebeta2 and gamma and the speech fluency of the subjects (beta2: r s -.31, p slt; .01; gamma: r s -.34, p slt; .05).
, the study found that the association between the split trait and the asymmetry of the electrocephalocephalus in the resting forehead may not be limited to a single band.
previous studies have also reported that the combined use of low-frequency and high-frequency (delta, theta, and beta2) of resting-state encephalopathic power is better able to predict the total score of split traits.
Although the split trait may be associated with different frequency bands of the resting frontal frontal brain electricity, there is always a negative correlation between the two, i.e. as the split trait increases, the subject may exhibit a decrease in the power of the left side relative to the right frontal leaf in the resting state.
the study was published in Cognitive Neuropsychiatry under the title Resting Frontal EEG expressy and schizotypal traits: a test-retest study.
