Open AccessReducing default mode network connectivity with mindfulness-based fMRI neurofeedback: a pilot study among adolescents with affective disorder history
Adolescents experience alarmingly high rates of major depressive disorder (MDD), however, gold-standard treatments are only effective for ~50% of youth. Accordingly, there is a critical need to develop novel i...

Domain-Agnostic Segmentation of Thalamic Nuclei from Joint Structural and Diffusion MRI
The human thalamus is a subcortical brain structure that comprises dozens of nuclei with different function and connectivity, which are affected differently by disease. For this reason, there is growing intere...

Constrained Self-supervised Method with Temporal Ensembling for Fiber Bundle Detection on Anatomic Tracing Data
Anatomic tracing data provides detailed information on brain circuitry essential for addressing some of the common errors in diffusion MRI tractography. However, automated detection of fiber bundles on tracing...

Open AccessFunctional Alterations in Cerebellar Functional Connectivity in Anxiety Disorders
Adolescents with anxiety disorders exhibit excessive emotional and somatic arousal. Neuroimaging studies have shown abnormal cerebral cortical activation and connectivity in this patient population. The specif...

Learning Anatomical Segmentationsfor Tractography from Diffusion MRI
approaches for diffusion MRI have so far focused primarily on voxel-based segmentation of lesions or white-matter fiber tracts. A drawback of representing tracts as volumetric labels, rather than sets of stre...

Neuroanatomical Prediction of Anhedonia in Adolescents
Anhedonia is a transdiagnostic risk factor implicated in mental illness onset, treatment non-response, and suicidal behaviors. Prior cross-sectional research in adults has shown that anhedonia is associated wi...

Hierarchical Clustering of Tractography Streamlines Based on Anatomical Similarity
Diffusion MRI tractography produces massive sets of streamlines that contain a wealth of information on brain connections. The size of these datasets creates a need for automated clustering methods to group th...
