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, …

Abnormal EEG Microstates Linked to Major Depression & Related Cognitive Impairment (2024 Study)

by GLOOM

In the quest to understand the enigmatic nature of depression, scientists are turning to the intricate patterns of brain activity, seeking clues hidden within the electrical storm of thoughts and emotions. By examining electroencephalography (EEG) microstates—brief, recurring patterns of brain activity—researchers have begun to piece together how depression alters the fundamental dynamics of the brain. …
