Spatial overlapping maps and scatter plots showing fALFF values of overlaps.
, 2015 A: SUC vs. CON and DR vs. CON. Overlap regions account for 20% of SUC vs. controls, 41.7% of DR vs. controls, and 15.9% of total respectively. The yellow parts represents brain regions with common fALFF changes between SUC vs.

Distinct Biotypes of Visual Perception in Major Depressive Disorder
Advanced Science, Volume 13, Issue 31, 4 June 2026.In a discover dataset (272 acute MDD patients), this work identifies a novel depression biotype characterized by impaired visual motion perception, using machine learning clustering. An independent dataset confirms the robustness of this biotype through cross‐validation and demonstrates its generalizability.

Aberrant Brain Entropy in Alzheimer's Disease: Evidence From a Resting‐State fMRI Study
Brain and Behavior, Volume 16, Issue 5, May 2026.ABSTRACT Background The neurodegenerative disorder, Alzheimer's disease (AD), is typified by insidious onset and increasing prevalence with advancing age. It primarily causes comprehensive functional decline in memory, language, and executive control.

Abnormal spontaneous brain activity in minimal hepatic encephalopathy: resting-state fMRI study
Diagnostic and Interventional Radiology, 2016 PURPOSEWe aimed to assess the abnormality of baseline spontaneous brain activity in minimal hepatic encephalopathy (MHE) by amplitude of low frequency fluctuation (ALFF) and fraction ALFF (fALFF).METHODSA total of 14 MHE patients and 14 healthy controls ...
