Vertex-Based Analysis of Cerebral Blood Flow and Fractional Amplitude of Low-Frequency Fluctuations (CBF-fALFF) Coupling in Moderate-to-Severe Traumatic Brain Injury During the First Year Post-Injury
… relationship between cerebral blood flow and neural activity–that can lead to cognitive and functional impairments. This study attempted to non-invasively investigate neurovascular coupling in patients with moderate to severe TBI (msTBI) during the first year post-injury using a …

Differentiating schizophrenic patients from healthy control; application of machine learning to resting state fmri
… approach that has grown in popularity is the use of machine learning algorithms to train classifiers to decode stimuli, mental states, behaviors and other variables of interest from fMRI data. Most of these studies focus on fMRI low frequency oscillations. This study focuses on the amplitude of …

Effect of scan time on resting state parameters
… decade the interest in studying the spontaneous low-frequency fluctuations (LFF) in a resting-state brain has steadily grown. By measuring LFF (< 0.08 Hz) in blood-oxygen-level-dependent (BOLD) signals, resting-state functional magnetic resonance imaging (rs-fMRI) has proven to be a powerful tool …

Neuroimaging study of prenatal alcohol exposure effects on structural and functional connectivity in children
… spectrum disorders (FASD) describe the spectrum of cognitive, behavioural and neurological impairments associated with prenatal alcohol exposure (PAE). Diffusion tensor imaging (DTI) and resting-state functional MRI (rs-fMRI) were used to assess effects of PAE on microstructural integrities of …
