Structural Characterization of Cardiac Free‐Running Purkinje Fibers Using Inhomogeneous Magnetization Transfer (ihMT): A Proof of Concept MRI‐Histology Approach

NMR in Biomedicine, Volume 39, Issue 6, June 2026.
The cardiac Purkinje network is essential for synchronized ventricular activation but remains difficult to visualize with conventional MRI due to limited structural contrast. This study demonstrates that inhomogeneous magnetization transfer imaging provides enhanced contrast that differentiates free‐running Purkinje fibers, Purkinje‐Myocardial Junction,

Elevated neurofilament light levels in acute anorexia nervosa are associated with alterations in white matter volume and connectivity networks

Journal of Child Psychology and Psychiatry, Volume 67, Issue 6, Page 907-918, June 2026.
Background Anorexia nervosa (AN) is a severe eating disorder associated with drastic reductions in gray and white matter (WM) volume and structural connectivity alterations. However, the hypotheses regarding underlying mechanisms are inconclusive. The current study investigated the relationships of WM volume as well as WM network architecture with ...

Double dissociation between conduction aphasia and conduction agraphia supports a ventro‐dorsal partition of the left arcuate fasciculus

Journal of Neuropsychology, Volume 20, Issue 2, Page 502-509, June 2026.
Abstract We identified in two awake surgery cases a postoperative double dissociation between phonological and graphemic output buffer deficits. Using lesion‐symptom mapping from ischaemic mini‐strokes and preoperative tractography, we demonstrated that the phonological (resp. graphemic) disorder fitted with ventral (resp.

Functional and structural connectivity of thalamic subnuclei in major depressive disorder at 7 Tesla

Psychiatry and Clinical Neurosciences, Volume 80, Issue 6, Page 477-489, June 2026.
Aims Major depressive disorder (MDD) is widely considered to be a mood disorder characterized by altered connectivity. The thalamus plays an important role in MDD by connecting large areas of the brain. Here, we explored thalamic connectivity in MDD at the subnuclear level using ultra‐high‐field MRI.

Looking Under the Hood of Elite Rowers: Skeletal Muscle Determinants of Rowing Performance

Scandinavian Journal of Medicine &Science in Sports, Volume 36, Issue 6, June 2026.
ABSTRACT We aimed to identify the physiological and muscle characteristics associated with mean power output in the final stage of a rowing incremental test in elite rowers. Twenty‐two national level rowers (n = 9 female) completed the following assessments (i) a 7‐stage incremental rowing ergometer test to determine V̇O2peak, maximal muscle ...
