Data from: Validation of diffusion tensor imaging measures of nigrostriatal neurons in macaques
Objective: Interpretation of diffusion MRI in the living brain requires validation against gold standard histological measures. We compared diffusion values of the nigrostriatal tract to PET and histological results in non-human primates (NHPs) with varying degrees of unilateral nigrostriatal injury induced by MPTP, a toxin selective for dopaminergic neurons. Methods: Sixteen NHPs had MRI and PET scans of three different presynaptic radioligands and blinded video-based motor ratings before and after unilateral carotid artery infusion of variable doses of MPTP. Diffusion measures of connections between midbrain and striatum were calculated. Then animals were euthanized to quantify striatal dopamine concentration, stereologic measures of striatal tyrosine hydroxylase (TH) immunostained fiber density and unbiased stereologic counts of TH stained nigral cells. Results: Diffusion measures correlated with MPTP dose, nigral TH-positive cell bodies and striatal TH-positive fiber density but did not correlate with in vitro nigrostriatal terminal field measures or in vivo PET measures of striatal uptake of presynaptic markers. Once nigral TH cell count loss exceeded 50% the stereologic terminal field measures reached a near zero floor effect but the diffusion measures continued to correlate with nigral cell counts. Conclusion: Diffusion measures in the nigrostriatal tract correlate with nigral dopamine neurons and striatal fiber density, but have the same relationship to terminal field measures as a previous report of striatal PET measures of presynaptic neurons. These diffusion measures have the potential to act as non-invasive index of the severity of nigrostriatal injury. Diffusion imaging of the nigrostriatal tract could potentially have diagnostic value in humans with Parkinson disease or related disorders.

Longitudinal white-matter abnormalities in sports-related concussion: a diffusion MRI study of the NCAA-DoD CARE Consortium
<p><b>Objective</b></p> <p>To study longitudinal recovery trajectories of white-matter after sports-related concussion (SRC), we performed diffusion tensor imaging (DTI) on collegiate athletes who sustained SRC. </p> <p><b>Methods </b></p> <p>Collegiate athletes (n=219, 82 concussed athletes, 68 contact-sport controls, and 69 non-contact-sport controls) were included from the Concussion Assessment, Research and Education (CARE) Consortium. The participants completed clinical assessments and DTI at four time points: 24-48-hours post-injury, asymptomatic state, seven days following return-to-play, and six-months post-injury. Tract-based spatial statistics were used to investigate group differences in DTI metrics and identify white-matter areas with persistent abnormalities. Generalized linear mixed models were used to study longitudinal changes and associations between outcome measures and DTI metrics. Cox proportional hazards model was used to study effects of white-matter abnormalities on recovery time. </p> <p><b>Results</b></p> <p>In the white matter of concussed athletes, DTI-derived mean diffusivity was significantly higher than the controls at 24-48 hours post-injury and beyond the point when the concussed athletes became asymptomatic. While the extent of affected white matter decreased over time, part of the corpus callosum had persistent group-differences across all the time points. Furthermore, greater elevation of mean diffusivity at acute concussion was associated with worse clinical outcome measures (i.e., Brief-Symptom-Inventory scores and symptom-severity scores) and prolonged recovery time. No significant differences in DTI metrics were observed between the contact-sport and non-contact-sport controls. </p> <p><b>Conclusions</b></p> <p>Changes in white matter were evident after SRC at six-months post-injury, but were not observed in contact-sport exposure. Further, the persistent white-matter abnormalities were associated with clinical outcomes and delayed recovery time.</p>

Aligned Diffusion Schroedinger Bridges
<p>We add the processed and prepared raw datasets for the D3PM dataset.</p> <p><br> <strong>Paper Abstract</strong><br> Diffusion Schrödinger bridges (DSB) have recently emerged as a powerful framework for recovering stochastic dynamics via their marginal observations at different time points. Despite numerous successful applications, existing algorithms for solving DSBs have so far failed to utilize the structure of aligned data, which naturally arises in many biological phenomena. In this paper, we propose a novel algorithmic framework that, for the first time, solves DSBs while respecting the data alignment. Our approach hinges on a combination of two decades-old ideas: The classical Schrödinger bridge theory and Doob’s h-transform. Compared to prior methods, our approach leads to a simpler training procedure with lower variance, which we further augment with principled regularization schemes. This ultimately leads to sizeable improvements across experiments on synthetic and real data, including the tasks of protein conformational changes and temporal evolution of cellular differentiation processes.</p>
