Source-space EEG functional connectivity and prediction of cognition in Parkinsons disease: No added benefit of individualized head models over standard templates

The paper evaluates if individualized head models improve source-space EEG functional connectivity predictions of cognition in Parkinson's disease, finding standard templates are sufficient.

Functional Topography of the Neocortex Predicts Covariation in Complex Cognitive and Basic Motor Abilities

The paper examines how functional topography of neocortical networks in midlife relates to covariation in motor and cognitive abilities, finding that motor ability reflects functional topography differences while hearing does not.

Associations between thinner retinal neuronal layers and suboptimal brain structural integrity: Are the eyes a window to the brain?

The paper examines the association between retinal neuronal layer thickness and brain structural integrity in midlife, finding thinner retinal layers correlate with reduced brain structural measures.

Pervasively thinner neocortex as a transdiagnostic feature of general psychopathology

The paper identifies a common pattern of reduced neocortical thickness across multiple psychiatric disorder categories and the general psychopathology factor.

Microstructural integrity of the major nuclei of the thalamus in Parkinson's disease

The paper examines microstructural changes in thalamic nuclei across cognitive stages of Parkinson's disease and finds increased mean diffusivity correlates with cognitive decline, particularly in the lateral dorsal nucleus.

Replicability of Structural Brain Alterations Associated with General Psychopathology: Evidence from a Population-Representative Birth Cohort

The paper replicates structural brain alterations linked to the p factor in a longitudinal cohort, finding support for cerebello-thalamo-cortical circuit and visual association cortex associations but not cerebellar morphology.

General Functional Connectivity: shared features of resting-state and task fMRI drive reliable and heritable individual differences in functional brain networks

This paper introduces General Functional Connectivity (GFC) to improve reliability and heritability of intrinsic connectivity estimates by combining resting-state and task fMRI data.

White matter hyperintensities are common in midlife and already associated with cognitive decline

This study finds that white matter hyperintensities (WMHs) are common in midlife and are associated with lower IQ and greater cognitive decline from childhood to midlife.
