Brain Function Disturbance and Partial Recovery After 6 Months in a Working Memory Task in Post COVID Patients
Impact: Post Covid-induced impairment of
brain activation patterns reflects patients’ cognitive disturbances. Our
finding of lacking adjustment of local brain activity to cognitive demands and its
partial recovery after 6 months provides important insights into mechanisms
underlying post COVID cognitive dysfunction.

Multimodal MRI reveal alterations in connectivity, cortical morphometry, and executive function in early abstinent meth users
Impact: Imaging and cognitive markers show that early-abstinent meth users exhibit disrupted network coupling, cortical thinning, and planning inefficiency. Translation into routine care can target rehabilitation plans, enable objective progress checks, and provide clearer prognoses to guide clinicians across addiction services.

Representations of visual-to-auditory sensory substitution in the visual cortices of early and late blind listeners
Impact: These
findings reveal how prior visual experience shapes cortical representations of
substituted visual space in the visual cortices of blind individuals. This
advances our understanding of both neuroplasticity and the mechanisms of how
sensory substitution devices can aid vision rehabilitation.

Graph Theory Analysis of rsfMRI Reveals Network Topology Disruptions in TBI: Implications for Biomarker Development
Impact: Graph theory-based analysis of resting-state
fMRI objectively quantifies network-level dysfunction in TBI. Reductions in
clustering coefficient and increases global efficiency provide neuroimaging
biomarkers, potentially enabling precision prognostication, correlation with
injury severity scores, and advancing network-based stratification in clinical
neurotrauma research.

Disrupted Static and Dynamic Brain Network Signatures in Drug-Naïve Early Parkinson’s Disease: A Connectome Perspective
Impact: This study identifies concurrent static and dynamic brain network disruptions in early, untreated Parkinson’s disease. These connectomic signatures link motor and cognitive symptoms to specific network dysfunctions, offering potential neuroimaging biomarkers for early diagnosis and therapeutic monitoring.

Investigating structure–function coupling in epilepsy patients undergoing RFTC with graph signal processing
Impact: This study will apply graph signal processing to characterize how radiofrequency thermocoagulation (RFTC) alters epileptic network organization and whether pre-RFTC structure–function coupling predicts treatment outcomes, potentially improving RFTC planning and advancing network-based understanding of epilepsy.

Scale-free dynamics of cerebrospinal fluid signals are linked to the pathology of Alzheimer’s disease.
Impact: CSF scale-free dynamics, measured by Hurst exponent from fMRI, correlate strongly with AD biomarkers (Aβ42, pTau). CSF-H represents a potential non-invasive imaging biomarker for detecting AD pathology and monitoring glymphatic-targeted therapies, enabling earlier diagnosis before cognitive decline

How do resilient minds differ? Neural correlates of resilience in inflammatory bowel disease explored with 7T fMRI
Impact: Findings reveal neural correlates in IBD, supporting a relationship between gut inflammation and brain function that may reduce resilience in chronic illness. These findings illuminate brain–gut–resilience interactions and suggest avenues for targeted interventions and improved patient outcomes.

Graph Theory Analysis of Brain Network Alterations in Migraine Patients with Patent Foramen Ovale
Impact: This study
demonstrates that altered nodal topological properties in brain networks may
contribute to migraine in PFO patients, providing preliminary neuroimaging
evidence that could enhance understanding of its pathophysiology and
potentially guide more precise diagnosis and targeted clinical interventions.

Functional connectivity alterations in insomnia across sleep-wake states: A pilot EEG-fMRI study
Impact: This study demonstrates that resting state functional
connectivity (rsFC) differs between participants with insomnia and healthy
age-matched controls across sleep-wake states. Independently
of depression, insomnia involves altered regional brain processing during
sleep.

Functional MRI of central auditory activation in adults with HIV: cortical and ART effects
Impact: Auditory fMRI reveals subtle cortical alterations in HIV-positive adults with normal hearing, undetectable by standard audiological tests. These findings support integrating neuro-functional MRI into HIV neuroimaging to detect early central auditory involvement and guide research on ART-related cortical reorganisation.

Vasomotor dysfunction in cerebral amyloid angiopathy (CAA) characterized by VASO and BOLD fMRI
Impact: Vascular
space occupancy (VASO) fMRI revealed vascular alterations in cerebral amyloid
angiopathy (CAA), offering novel insight into cerebrovascular dysfunction and
neurovascular coupling deficits beyond conventional BOLD imaging, advancing our
understanding of disease mechanisms and suggesting it as potential biomarker.

Multimodal Behavioral and MRI Examination of Blast-Induced Mild Traumatic Brain Injury (mTBI) in Awake Mice
Impact: This study uses advanced MRI and behavioral measures to identify objective, multimodal biomarkers for mTBI-induced emotional dysfunction. The findings are intended to inform targeted treatment strategies and improve clinical prognostics.
