Effective Connectivity Alterations among Intrinsic Brain Networks Predict Chronic Post-Traumatic Headache after Mild TBI
Impact: Our findings reveal
that causal network dysfunction within the triple-network system drives the
chronification of post-traumatic headache after mTBI. These effective
connectivity biomarkers may guide early identification and personalized
neuromodulatory intervention for patients at risk of chronic headache.

Prediction of Cognitive Function Based on fALFF and Reho In Subcortical Ischemic Vascular Disease and Alzheimer’s Disease.
Impact: This study showed that ReHo and fALFF
measured in cognition-related regions predict MMSE in AD and SIVD, supporting
brain-network mechanisms of global cognition and informing clinical diagnosis,
treatment, and rehabilitation planning.

Acupuncture Selectively Restores Baseline-Impaired Brain Networks in Migraine: Implications for Mechanism and Treatment Strat
Impact: We identify network biomarkers linking acupuncture-induced connectivity changes to symptom relief, enabling subject stratification and endpoint design. Results suggest treatment preferentially restores baseline-impaired edges rather than rapidly reconfiguring global topology.

Neural Activation To High- And Low-Calorie Food Words Among Healthy Volunteers: A Pilot Study
Impact: This
ongoing pilot study presents a task-based fMRI protocol in healthy individuals, providing preliminary data on cognitive and emotional responses to food
cues, with potential relevance for future research in individuals with excess weight.

Reproducibility of a Motor-Imagery fMRI Paradigm in Healthy Volunteers: Benchmarking for Clinical Application
Impact: This study
demonstrates a reproducible motor imagery fMRI paradigm in healthy volunteers,
yielding reliable cortical activations within the SMA and PMC. These
reproducibility benchmarks strengthen the paradigm’s translational potential
for early detection of cognitive motor dissociation in clinical practice.

Decision-Making and Functional Connectivity during Iowa Gambling Task in Parkinson’s Disease: An fMRI Study
Impact: Parkinson’s disease (PD) patients exhibit functional connectivity in
anterior cingulate (ACC), posterior cingulate (PCC) and Fronto-orbital regions
during an fMRI-based Iowa Gambling Task (IGT). These findings identify network
biomarkers of impaired decision-making in PD and suggest targets for
interventions.

Arousal-Driven Dynamics of Frequency-Resolved Brain States in Resting-State fMRI
Impact: Our results reveal frequency-specific alterations in brain
state dynamics during drowsiness, providing improved arousal markers that can
refine preprocessing, strengthen resting-state biomarkers, and support research
on fatigue, sleep, and disorders characterized by disrupted arousal.

Does cerebrovascular reactivity lag heterogeneity underlie breath-hold RSN mimicry?
Impact: Advances in disentangling neuronal and vascular origins of RSN-like BOLD patterns are critical—not only for minimizing non-neuronal confounds but also for a more accurate interpretation of neurological and psychiatric studies associated with altered BOLD RSNs.

Neuroimaging Genomic Characteristics of Brain Following a 60-Day Simulated Microgravity Induced by Head-Down Tilt Bed Rest
Impact: This study
provides actionable biomarkers for monitoring the central nervous system of
astronauts and the deeper exploration of brain function may be important for
understanding the role and effects of microgravity on brain health.

Structural brain harmonics as a basis for functional integration-segregation continuum in MEG
Impact: We
demonstrate that a brain harmonics-based framework provides a unifying
continuum between integrative and segregative structural and function
properties of the brain, that these properties extend to MEG derived functional
recordings, and present novel frequency dependent structure-function
relationships.
