The ability to sustain attention differs across people and changes within a single person over time. Although recent work has demonstrated that patterns of functional brain connectivity predict individual differences in sustained attention, whether these same capture fluctuations individuals remains unclear. Here, five independent studies, we demonstrate the connectome-based predictive model (CPM), validated function, generalizes attentional state from data collected minutes, days, weeks,...
Patterns of whole-brain fMRI functional connectivity, or connectomes, are unique to individuals. Previous work has identified subsets connections within these patterns whose strength predicts aspects attention and cognition. However, overall features such as how stable they over time similar a group-average (typical) high-performance (optimal) connectivity pattern, may also reflect cognitive attentional abilities. Here, we test whether individuals who express more stable, typical, optimal,...
Significance Given that using multiple languages incorporates cognitive functions require a harmony of the whole brain, can we tell whether child is monolingual or multilingual by only looking at pattern functional connectivity? Here, show experience modulates connections multilinguals enough to be distinguished from monolinguals. The distinctive when children are performing an emotional n-back task and even rest. Furthermore, found have stronger relationship between their working-memory...
The human brain flexibly controls different cognitive behaviors, such as memory and attention, to satisfy contextual demands. Much progress has been made reveal task-induced modulations in the whole-brain functional connectome, but we still lack a way model context-dependent changes. Here, present novel connectome-to-connectome (C2C) transformation framework that enables us brain's reorganization from one connectome state another response specific task goals. Using magnetic resonance imaging...
Abstract Heterogeneity in brain activity can give rise to heterogeneity behavior, which turn comprises our distinctive characteristics as individuals. Studying the path from however, often requires making assumptions about how similarity behavior scales with activity. Here, we expand upon recent work (Finn et al., 2020) proposes a theoretical framework for testing validity of such assumptions. Using intersubject representational analysis two independent movie-watching functional MRI (fMRI)...

Much progress has been made reveal task-induced modulations in the whole-brain functional connectome, but we still lack a way model changes brain’s organization. Here, present novel connectome-to-connectome (C2C) state transformation framework that enables us reorganization response specific task goals. Using magnetic resonance imaging data from Human...
A number of studies have found that bilinguals differ from monolinguals not only in verbal aspects but also nonverbal cognitive functions. This study aims to investigate whether learning a third language affects our executive To demonstrate direct effect (German) function, 32 English-Korean participated the ERP experiments twice: before and after training. Based on Dual Mechanism Control (DMC) model, we used an AX-CPT paradigm analyze proactive control processing with P3b reactive N2 P3a...
Abstract Attention is central for many aspects of cognitive performance, but there no singular measure a person’s overall attentional functioning across tasks. To develop universal that integrates multiple components attention, we collected data from more than 90 participants performing three different attention-demanding tasks during fMRI. We constructed suite whole-brain models can predict profile – sustained divided attention and tracking, working memory capacity single fMRI scan type...
