Building an open infrastructure for molecular neuroimaging: standards and tools from the OpenNeuroPET initiative

The paper describes the OpenNeuroPET initiative, which develops standards and open-source tools to standardize and share PET neuroimaging data, enhancing reproducibility and collaboration.

Psilocybin acutely reduces low-frequency BOLD power and frequency-specific connectivity

This study shows psilocybin reduces low-frequency BOLD power and alters frequency-specific connectivity in the brain.

Inter-individual variability of neurotransmitter receptor and transporter density in the human brain

This study quantifies inter-individual variability in PET-estimated receptor and transporter density across 12 neurotransmitter systems in the human brain.

Building Multivariate Molecular Imaging Brain Atlases Using the NeuroMark PET Independent Component Analysis Framework

The paper introduces NeuroMark PET, an automated framework using spatially constrained ICA to identify Aβ networks in PET data, showing higher sensitivity for age-related changes compared to traditional ROIs.

Multimodal brain age prediction using machine learning: combining structural MRI and 5-HT2AR PET derived features

This study predicts brain age using 5-HT2AR PET and MRI data, finding that combining both improves accuracy compared to using either modality alone.

Prediction of brain age using structural magnetic resonance imaging: A comparison of accuracy and test-retest reliability of publicly available software packages

This study compares six brain age prediction software packages using MRI data, finding pyment and brainageR to be most accurate and reliable.

Mapping neurotransmitter systems to the structural and functional organization of the human neocortex

Neurotransmitter receptor/transporter PET maps (19 targets, 1239 healthy participants) align with connectomes, explain MEG power, and track cognitive gradients and cortical thinning in 13 disorders.

PET-BIDS, an extension to the brain imaging data structure for positron emission tomography

The paper introduces PET-BIDS, an extension of the BIDS standard for PET data, and provides curated datasets and tools for its use.

A High-Resolution In Vivo Atlas of the Human Brain's Benzodiazepine Binding Site of GABAA Receptors

The paper creates a high-resolution in vivo atlas of benzodiazepine receptor densities in the human brain using PET and autoradiography data, linking it to GABAAR subunit mRNA expression.
