Sampling of non‐Gaussian Ensemble Average Propagators for the simulation of diffusion magnetic resonance images

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 2, Page 1255-1265, February 2026.
Abstract Purpose (a) To design a methodology for drawing random samples of any Ensemble Average Propagator (EAP) (b) to modify the KomaMRI simulator to accommodate them as realistic spin movements to simulate diffusion MRI (dMRI) and (c) to compare these simulations with those based on the Diffusion Tensor (DT) model.

Combined Neuroprotective Effects of N,N‐Dimethyltryptamine and Ventral Root Reimplantation Following Spinal Root Avulsion in Rats

open access: yesJournal of Neurochemistry, Volume 170, Issue 2, February 2026.
The ventral root avulsion (VRA) model provides an excellent experimental paradigm for studying injuries at the Central/Peripheral Nervous Systems (CNS/PNS) interface. By physically disconnecting motoneurons (MNs) from the spinal cord surface, VRA induces profound cellular, molecular, and functional deficits with limited spontaneous recovery.

AAV‐Driven miR‐146a Promotes Neurite Outgrowth and Axonal Regeneration in Cortical Neurons

open access: yesJournal of Neurochemistry, Volume 170, Issue 2, February 2026.
In the adult central nervous system (CNS), neuronal regeneration after injury is limited, resulting in poor functional recovery. MicroRNAs (miRNAs), a class of small noncoding RNAs that control gene expression, have gained attention as potential therapeutic agents, although their contribution to CNS repair remains insufficiently understood.

Comparison of drone and ground surveys for the detection of a rare plant in a fragile ecosystem

open access: yesEcological Solutions and Evidence, Volume 7, Issue 1, January–March 2026.
We compared the accuracy, time, and financial costs of drone and ground surveys for the detection of wood lilies (Lilium philadelphicum) in an endangered alvar ecosystem. We found that the drone surveys detected 73%–78% of the plants found in the ground surveys, but that this type of survey was more expensive and time consuming than the ground survey ...

Robust regression for large-scale neuroimaging studies [PDF]

open access: yes, 2015
Multi-subject datasets used in neuroimaging group studies have a complex structure, as they exhibit non-stationary statistical properties across regions and display various artifacts.

Thermal noise lowers the accuracy of rotationally invariant harmonics of diffusion MRI data and their robustness to experimental variations

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 1, Page 204-219, January 2026.
Abstract Purpose Rotational invariants (RIs) are at the root of many dMRI applications. Among others, they are presented as a sensible way of reducing the dimensionality of biophysical models. While thermal noise impact on diffusion metrics has been well studied, little is known on its effect on spherical harmonics‐based RI (RISH) features and derived ...
