Open-access template and database approaches for pseudo-CT generation in brain PET/MRI attenuation correction

The paper presents an open-access framework for PET attenuation correction using pseudo-CT methods with a database of MRI-CT scans, showing that UCL achieves the lowest quantification error.

Connecting the Dots: Approaching a Standardized Nomenclature for Molecular Connectivity Combining Data and Literature

The paper introduces a standardized nomenclature for PET-based molecular connectivity and covariance to improve reproducibility and interpretation across imaging modalities and radiotracers.

Regional gene expression patterns are associated with task-specific brain activationduring reward and emotion processing measured with functional MRI

The paper correlates gene expression patterns with fMRI activation maps during reward and emotion tasks, identifying gene regulators linked to depression risk.

Correlation of receptor density and mRNA expression patterns in the human cerebral cortex

The paper examines the correlation between mRNA expression and receptor density in the human cerebral cortex using autoradiography and transcriptomic data from multiple sources.

Escitalopram Administration, Neuroplastic Effects and Relearning: A Diffusion Tensor Imaging Study in Healthy Individuals

This study investigates escitalopram's effect on white matter plasticity during learning and relearning using diffusion tensor imaging in healthy individuals, finding no significant changes in DTI metrics.

Effects of Escitalopram and Relearning on Cortical and Subcortical Grey Matter in Healthy Humans

This study examines the effects of escitalopram and relearning on grey matter in healthy humans but finds no significant effect of the SSRI on structural neuroplasticity during relearning.

Enrichment of disease-associated genes in cortical areas defined by transcriptome-based parcellation

The paper identifies cortical areas with enriched disease-associated genes using transcriptome-based parcellation and GWAS data, revealing potential roles in psychiatric and neurological disorders.

Serotonin modulates learning content-specific neuroplasticity of functional brain networks

This study shows that escitalopram modulates functional brain network connectivity during relearning, with content-specific effects on neuroplasticity.

Differential brain atrophy and neurogenetic profiles in cognitively-defined Alzheimer's disease subgroups

The paper identifies cognitive subgroups in Alzheimer's disease based on MRI-derived atrophy patterns and links them to specific biological pathways using transcriptomic data.
