The paper maps the morphological and functional maturation of human endocrine pancreas from birth to age 10 using pediatric tissue samples and imaging techniques.

In 299 islet preparations from donors without diabetes, endocrine cell composition, not donor demographics, tracked insulin secretion, and δ cell percentage rose with type 2 diabetes genetic risk.

This paper analyzes peri-ictal network dynamics in drug-resistant epilepsy patients to show that NIZs increase inhibitory signaling to SOZs during seizures, but this suppression is insufficient to prevent seizure onset.

This study examines how connectivity patterns of arousal regulation centers change with vigilance states using EEG and fMRI, showing distinct network correlations in low and high alertness.

The paper examines how motor control affects mesolimbic local field potentials using electrophysiological recordings during a stop-signal task.

The paper analyzes longitudinal MRI data from 1,293 subjects to study age-related changes in superficial white matter microstructure and U-fiber volume and length.

The paper tests the interictal suppression hypothesis in focal epilepsy using electrographic and structural data to identify seizure onset zones and develop a classification model with high accuracy.

The paper quantifies resting-state BOLD hemodynamic response functions (HRF) in white matter, showing significant differences from gray matter and variation along WM pathways.

This study analyzes diffusion MRI data from 1184 participants to quantify age-related changes in white matter microstructure and macrostructure, finding that macrostructural features show more heterogeneous age-related decline.

This study validates diffusion MRI as a tool to assess nerve regeneration in rat models of peripheral nerve trauma, showing it can distinguish successful from unsuccessful repairs.

The paper evaluates tractography reproducibility using empirical data from a single healthy volunteer scanned on two scanners, finding high consistency among top algorithms but variability due to tract volume containment.
