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.

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

This study identifies common cortical folding patterns across age groups using hierarchical surface registration, revealing hemispheric asymmetry and dissociation between folding and functional organisation.

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

This study examines the relationship between hyperventilation, EEG frequency band power, and thalamic blood flow in individuals with idiopathic generalized epilepsy compared to healthy controls.

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.

The paper introduces a database of 37 normal adult human brain FDG PET, T1, FLAIR MRI, and CT images for research, including acquisition parameters, processing pipelines, and demographic data.

This study uses MEG and pharmacological intervention to map GABAA receptor distribution by analyzing changes in brain oscillations induced by tiagabine.
