Altered Spontaneous Brain Activity in Adolescents and Adults with Comitant Strabismus and Strabismic Amblyopia [PDF]

Ophthalmology Science
Purpose: Neuroimaging studies have established that strabismus and amblyopia are associated with structural and functional brain alterations. However, differences in spontaneous brain activity between strabismus patients with and without amblyopia remain

The relationship between fractional amplitude of low-frequency fluctuations (fALFF) and the severity of neglect in patients with unilateral spatial neglect (USN) after stroke: A functional near-infrared spectroscopy study

IBRO Neuroscience Reports
Objective: Unilateral spatial neglect (USN) following right hemisphere stroke is more pronounced, severe, and persistent than in the left hemisphere. However, the pathophysiological mechanisms underlying USN remain largely unknown.

Differentiating Melancholic and Non-melancholic Major Depressive Disorder Using Fractional Amplitude of Low-Frequency Fluctuations

Frontiers in Psychiatry, 2022
BackgroundMelancholic major depressive disorder (MDD) is a network-based brain disorder. However, whether or not network-based changes can be applied to differentiate melancholic (MEL) from non-melancholic (NMEL) MDD remains unclear.MethodsThirty-one MEL
