Intratumoral and Peritumoral Functional Connectivity Reveals Network‐Level Signatures of Glioma

MedComm, Volume 7, Issue 11, November 2026.
Using resting‐state fMRI in 306 glioma patients, this study maps individualized intra‐ and peritumoral functional networks. Novel metrics (RIFR, RPTR) quantify tumor‐related network remodeling, correlating with pathology, structure, cognition, and survival. A prognostic model incorporating these network features achieves an AUC of 0.90.

Suppression of Oscillation and Ghosting in RF‐Spoiled Gradient‐Echo‐Based Dynamic Imaging

Magnetic Resonance in Medicine, Volume 96, Issue 5, Page 2177-2187, November 2026.
ABSTRACT PurposeThis study aims to address the suppression of oscillation and ghosting appearing in RF‐spoiled gradient‐echo‐based dynamic imaging, which is caused by the pseudo‐steady state (PSS) of magnetization. Theory and MethodsWe extended the concept of the previous RF phase‐cycle‐adapted averaging method to RF‐spoiled gradient‐echo‐based cine ...

Assessment of Cerebral Perfusion Asymmetry in Chronic Migraine Patients Using Intravoxel Incoherent Motion (IVIM)–Derived Pseudodiffusion Coefficient and Perfusion Fraction

NMR in Biomedicine, Volume 39, Issue 11, November 2026.
ROI‐based quantitative IVIM‐DWI analysis demonstrated significantly greater interhemispheric asymmetry of the composite perfusion parameter fD* in the posterior thalamus in chronic migraine during the interictal phase compared with control subjects. In contrast, pain‐implicated cortical loci showed no significant interhemispheric perfusion asymmetry ...

Inferior Frontal Gyrus Alterations in Freezing of Gait in Parkinson's Disease Without Evidence for Overall Hemispheric Lateralization: A Systematic Review and Activation Likelihood Estimation Meta‐Analysis

European Journal of Neuroscience, Volume 64, Issue 9, November 2026.
Our systematic review included 108 neuroimaging articles examining freezing of gait in Parkinson's disease, with 33 included in the primary activation likelihood estimation meta‐analysis. We assessed spatial convergence and hemispheric lateralization of reported abnormalities, identifying the right inferior frontal gyrus as the main convergent region ...

Drowsiness increases slow oscillations in rs-fMRI signal before sleep onset

International audienceSleep can significantly affect the functional MRI (fMRI) signal as reported in previous studies where subjectswere allowed to fall asleep during the examination (Fukunaga et al., 2006, Duyn 2019).

Cortical Adaptation to Muscle Fatigue Does Not Alter Early Proprioceptive Processing in Primary Sensorimotor Cortex

European Journal of Neuroscience, Volume 64, Issue 9, November 2026.
Cortical proprioceptive responses to passive ankle‐joint movement are negligibly affected by muscle fatigue. Intriguingly, fatigue‐induced increases in alpha and beta power extend beyond the SM1 foot region to bilateral hand regions, which may facilitate more focused lower‐limb proprioceptive processing, thus compensating for asynchronous ...
