Precision fMRI reveals densely interdigitated network patches with conserved motifs in the lateral prefrontal cortex

The paper uses precision fMRI to reveal individual-specific, fragmented, and interdigitated network patches in the lateral prefrontal cortex, showing conserved motifs and distinct functional boundaries not visible in group-averaged data.

Two common and distinct forms of variation in human functional brain networks

This paper identifies two distinct forms of variation in human functional brain networks: border shifts and ectopic intrusions, which differ in location, network associations, and behavioral predictions.

The interaction between random and systematic visual stimulation and infraslow quasiperiodic spatiotemporal patterns of whole brain activity

This paper investigates how systematic and random visual stimulation affects infraslow quasiperiodic spatiotemporal patterns (QPP) of whole-brain activity and finds distinct impacts on QPP waveform characteristics and frequency.

Brain hubs defined in the group do not overlap with regions of high inter-individual variability

The paper investigates the relationship between brain hubs and inter-individual variability, finding that group hubs defined by participation coefficient are consistent across individuals, while other hub measures show higher correspondence to individual variability.

From Correlation to Communication: disentangling hidden factors from functional connectivity changes

This paper introduces a method to disentangle non-local network input from task-induced changes in functional connectivity using BOLD fMRI signals and demonstrates its effectiveness in distinguishing task types.

The cingulo-opercular network is composed of two distinct sub-systems

This paper identifies two distinct sub-systems within the cingulo-opercular network using fMRI data, showing differential roles in task control and other cognitive/motor functions.

BOLD cofluctuation 'events' are predicted from static functional connectivity

The paper examines whether high cofluctuation 'events' in fMRI data uniquely drive functional connectivity or arise from sampling variability in a static signal.

Prefrontal-posterior coupling mediates emotion transitions and their influence on executive function

The paper examines how emotion transitions affect executive function through prefrontal-posterior brain synchronization, showing stress exacerbates these effects.
