Brain entropy and human intelligence: A resting-state fMRI study

open access: yesPLoS ONE, 2018
Human intelligence comprises comprehension of and reasoning about an infinitely variable external environment. A brain capable of large variability in neural configurations, or states, will more easily understand and predict variable external events ...

White Matter Dysfunction and Neurotransmitter Basis Underlying the Freezing of Gait in Parkinson's Disease

open access: yesiNew Medicine, EarlyView.
In the freezing of gait in Parkinson's disease, white matter shows decreased local activity but increased functional connectivity. These distinct dysfunctions are uniquely associated with specific neurotransmitter systems (GABA, dopamine, etc.), mapping a new neurochemical basis for this debilitating symptom. ABSTRACT Freezing of gait (FOG) is a severe

Mind over chatter: plastic up-regulation of the fMRI alertness network by EEG neurofeedback [PDF]

open access: yes, 2012
EEG neurofeedback (NFB) is a brain-computer interface (BCI) approach used to shape brain oscillations by means of real-time feedback from the electroencephalogram (EEG), which is known to reflect neural activity across cortical networks.

Comparing resting state fMRI de-noising approaches using multi- and single-echo acquisitions

open access: yesPLoS ONE, 2017
Artifact removal in resting state fMRI (rfMRI) data remains a serious challenge, with even subtle head motion undermining reliability and reproducibility.

Application of Machine Learning in the Diagnosis and Prognosis of Mild Traumatic Brain Injury Using Diffusion Tensor Imaging: A Systematic Review

open access: yesJournal of Magnetic Resonance Imaging, Volume 63, Issue 2, Page 328-345, February 2026.
ABSTRACT Background Traumatic Brain Injury (TBI) is a global health concern, with mild TBI (mTBI) being the most common form. Despite its prevalence, accurately diagnosing mTBI remains a significant challenge. While advanced neuroimaging techniques like diffusion tensor imaging (DTI) offer promise for more robust diagnosis, their clinical application ...

Pharmacological MRI: Utility in Understanding Drug Mechanisms in Psychiatric Disorders

open access: yesJournal of Magnetic Resonance Imaging, Volume 63, Issue 2, Page 346-363, February 2026.
ABSTRACT Pharmacological MRI (pharmaMRI) has emerged as a powerful tool to study how psychoactive drugs affect brain function and to uncover mechanisms of drug action in psychiatric disorders. This review provides an overview of key techniques used in pharmaMRI, including BOLD‐fMRI, arterial spin labeling (ASL), and cerebral blood volume (CBV) mapping,

Hemodynamic response function (HRF) variability confounds resting‐state fMRI functional connectivity

open access: yesMagnetic Resonance in Medicine, 2018
fMRI is the convolution of the hemodynamic response function (HRF) and unmeasured neural activity. HRF variability (HRFv) across the brain could, in principle, alter functional connectivity (FC) estimates from resting‐state fMRI (rs‐fMRI).

Developmental Brain Age Estimation From MRI Data: A Systematic Review of Deep Learning Approaches and Open Datasets

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Brain age is an emerging concept that reflects complex, time‐dependent changes in brain structure, identifying departures from expected neurodevelopmental patterns. In the developing brain, accurate MRI‐based age estimation is a quantitative biomarker for detecting atypical neurodevelopment, facilitating early diagnosis, guiding clinical ...
