Objective Quality Assessment for Precision Functional MRI Data

The paper introduces NSI, an objective measure to assess data quality for precision functional MRI, aligning with expert evaluations and enabling principled decisions on data sufficiency.

Strategies for motion- and respiration-robust estimation of fMRI intrinsic neural timescales

This study evaluates how motion and respiration artifacts affect intrinsic neural timescale estimation in fMRI and tests denoising strategies to mitigate these effects.

Expansion of a frontostriatal salience network in individuals with depression

The paper identifies a two-fold expansion of the frontostriatal salience network in individuals with depression using longitudinal neuroimaging data and shows its stability over time and predictive value for future symptoms.

A mind-body interface alternates with effector-specific regions in motor cortex

The paper reveals that motor cortex contains inter-effector regions connected to the Cingulo-opercular network, alternating with effector-specific areas, suggesting a dual system for motor control and whole-body coordination.

Distinctions among real and apparent respiratory motions in human fMRI data

The paper analyzes fast-sampling fMRI data to distinguish real and apparent respiratory motions, identifying five types of respiratory motion and reformulating motion estimates.

Characteristics of respiratory measures in young adults scanned at rest, including systematic changes and \"missed\" respiratory events

The paper evaluates three respiratory measures in resting state fMRI scans of healthy young adults, finding they all miss respiratory events and decrease systematically over time.

Reward-related regions form a preferentially coupled system at rest

The paper identifies a distinct reward-related functional system using resting-state functional connectivity, showing preferential coupling with cognitive control systems.
