Test-Retest Reliability of Coherence Measures of Qeeg During Resting State
… emphasis in quantitative electroencephalography (qEEG) research on measures of absolute power, recent research has suggested the importance of other qEEG measurements (i.e., coherence and phase lag) as indicators of cognitive function. Coherence has been shown to relate to general intelligence …

Lived Experiences of Post-Master's Counselors Using qEEG Data When Treating Clients
… experiences of post-master's counselors using qEEG data when treating clients. This study focused on the lived experiences of post-master's counselors and their use of qEEG data for client treatment, collecting data from a sample of 5 post-master's counselors using semi-structured interviews. …

QEEG and MMPI-2 patterns of adults reporting childhood sexual abuse: Determining differences and predictor models.
… in quantitative electroencephalography (QEEG) patterns in these individuals. The purpose of this study is to determine differences seen in the MMPI-2 and the QEEG when comparing adults who report CSA to adults who deny any history of childhood abuse. Differences between the two groups in …

Hostile-Diabetic Men: An Examination of Peripheral Glucose and QEEG Magnitudes Subsequent to Lateralized Fluency-Stressors
… as measured as by peripheral glucose and QEEG magnitudes, as a result of modest regulatory capacity subsequent to right frontal lobe stress. Moreover, it was expected that high hostile-diabetics would show diminished performance on neuropsychological indicants of right frontal functions.

Effects of Childhood Sexual Abuse on Brain Function as Measured by Quantitative EEG, Neuropsychological, and Psychological Tests
… CSA, quantitative electroencephalographic (QEEG), neuropsychological, and psychological measurements in 24 high-functioning, unmedicated CSA adults who were matched for age, gender, and handedness with a group of adults without CSA (NCSA). The objectives of this study were to: 1) examine EEG …

Resting-State EEG Spectral Activity in Children and Adolescents with ASD: Potential Correlations with Interoceptive Neocortical Areas
… <p>This study aims to compare resting-state EEG (QEEG) activity between children and adolescents with ASD and neurotypical (TD) peers, and to explore the relationship between interoceptive processing and ASD diagnosis. Archival QEEG data from individuals aged 4–17 were analyzed.</p> <p>A …

The Effectiveness of EEG Biofeedback and Cognitive Rehabilitation as Treatments for Moderate to Severe Traumatic Brain Injury
… treatments. Quantitative electroencephalographs (qEEG) were also administered pre-post treatments to evaluate any change in the electrophysiological dynamics of the brain. Results: EEG biofeedback appeared to be more effective than cognitive rehabilitation in improving information processing …

Parameters Characterization and Cognitive-Behavioral Effects of Transcranial Pulsed Current Stimulation
… of tPCS in quantitative electroencephalography (qEEG) and cognitive-behavioral testing by exploring different parameters of stimulation. Based in the findings obtained per experiment, tPCS can be defined as a safe and tolerable technique that modulates the power spectrum of qEEG signals by means …

Challenging frontal lobe capacity using lateralized vestibular stress: A functional cerebral systems approach to a clinical risk for falls
… a design fluency task would yield differences in QEEG and skin conductance after vestibular activation. Fifty-eight total (29 high- and 29 low-fluent performers on the Ruff Figural Fluency Test were subjected to 20 whole-body passive rotations about the neuroaxis at a constant rate of …

Neuropsychological Effects of Hostility and Pain on Emotion Perception
… quantitative electroencephalography (QEEG) was used to measure changes in cerebral activation as a result of auditory emotion perception and cold pressor pain. Results indicated that identification of emotion post-cold pressor differed as a function of hostility level and ear. The high …

Electrical Brain Activity and The Examinee's Level of Effort During Performance Validity Tasks
… via Quantitative Electroencephalography (QEEG) relates to mental effort during cognitive tasks. The purpose of this study was to investigate electrical brain activity, as measured by Peak (PK) frequency, on frontal brain areas (i.e. locations F3-F4) in individuals giving poor mental …

Exploring the combined use of electrical and hemodynamic brain activity to investigate brain function
… functioning in health and disease, measured with QEEG and NIRS, in order to evaluate its clinical potential. First the limitations of NIRS were investigated, depicting its susceptibility to different types of motion artefacts and the inability of the CBSI-method to remove them from resting state …

Clustering of Behavioral Data for Identification of Presumptive Subtypes of Attention Deficit/Hyperactivity Disorder in Children
… tests measuring inattention and impulsivity, and QEEG data measuring brain wave information. A multi-modal approach to investigating symptom subtypes of AD/HD would likely provide increased reliability and validity of differential diagnosis, and therefore, more effective treatment of children with …

A Functional Cerebral Systems Approach to Hostility: Changes in Frontal Lobe Delta Activation and Fluency Performance as a Function of Stress
Executive functions, potentially including the regulatory control of emotions and expressive fluency (verbal or design), have historically been associated with the frontal lobes. Moreover, research has demonstrated the importance of cerebral laterality with a prominent role of the right frontal …

Prediction of the Outcome in Cardiac Arrest Patients Undergoing Hypothermia Using EEG Wavelet Entropy
<p>Cardiac arrest (CA) is the leading cause of death in the United States. Induction of hypothermia has been found to improve the functional recovery of CA patients after resuscitation. However, there is no clear guideline for the clinicians yet to determine the prognosis of the CA when patients …
