A 2026 medRxiv preprint did not find one simple autism excitation-inhibition signature. Bertelsen et al. found 2 EEG-derived E:I neurosubtypes in 286 autistic males: a 47% inhibition-dominant subtype with higher Hurst exponent and lower gamma, and a 53% excitation-dominant subtype with the opposite pattern.1 Research Highlights Two subtypes, opposite directions: in 286 autistic males ages …
A 2026 diagnostic-accuracy preprint found that resting-state EEG network features separated non-lesional epilepsy from functional/dissociative seizures (FDS) at 67.5% balanced accuracy, but the signal was not symmetrical: sensitivity was 81.8% for epilepsy and only 53.3% for FDS.1 In plain clinical terms, the model looked more useful as an epilepsy-supporting marker than as a positive test …
A 2026 EEG study of 106 Army National Guard recruits found that higher negative emotionality predicted poorer Go/No-Go discrimination (β = −.234, 95% CI −.392 to −.076) and lower frontal midline theta (β = −.149, 95% CI −.290 to −.001). The key result was not a vague personality-brain link: frontal midline theta, not occipital alpha, …
A 2026 eNeuro analysis of 163 people ages 3.5–24.7 found that wake EEG amplitude behaved like a sleep-pressure marker, but wake alpha-density changed in opposite directions across development: it decreased overnight in children and increased overnight in adolescents and adults.1 Research Highlights Alpha density flipped by age: In 163 participants ages 3.5–24.7, oscillation density showed …
Depression is a multifaceted mental health condition that presents significant challenges in both diagnosis and treatment. Recent studies have explored the potential of electroencephalography (EEG) as a predictive tool for treatment outcomes in major depressive disorder (MDD), with particular focus on the response to antidepressants like escitalopram. Highlights: EEG Abnormalities & Antidepressant Response: Contrary to …
Repetitive transcranial magnetic stimulation (rTMS) is making waves in the field of Alzheimer’s disease (AD) research, offering a glimmer of hope for enhancing cognitive functions in patients. By targeting specific brain regions, rTMS has shown promising results in modulating neural activity and improving cognitive scores. This innovative therapy, coupled with real-time monitoring through electroencephalography (EEG), …
Symptom provocation, a cornerstone of psychiatric research and therapy, offers a fascinating glimpse into the intricate relationship between brain activity and psychiatric symptoms. By deliberately triggering symptoms, researchers and clinicians can identify neurophysiological biomarkers and target them with personalized therapies, such as transcranial magnetic stimulation (TMS). This technique not only enhances our understanding of psychiatric …
