Background:

Functional neuroimaging studies often examine task-based activations, but changes in functional brain network organization during complex decision-making remain under-explored.
The Iowa Gambling Task (IGT) is a widely used paradigm for studying decision-making under uncertainty.

Purpose of the Study:

To investigate alterations in functional brain network organization from a resting state to the Iowa Gambling Task (IGT) using graph theory.
To assess the stability of functional network organization across repeated resting-state and IGT scanning sessions.

Main Methods:

Employed a repeated-measures design analyzing functional brain network organization during rest and IGT performance.
Utilized a graph-theoretical approach to quantify network properties.
Conducted regional analyses on the Default Mode Network (DMN) and Fronto-Parietal Network (FPN).

Main Results:

Global functional brain network organization transitioned from a locally clustered state at rest to a globally integrated state during the IGT.
Functional network organization demonstrated stability across multiple scanning sessions for both rest and IGT conditions.
Differential changes in regional network organization were observed between rest and IGT, particularly within the FPN.

Conclusions:

Global and regional brain network organization are significantly modulated by cognitive state (rest vs. IGT) and remain relatively stable over time.
Changes within the Fronto-Parietal Network (FPN) are critically involved in the decision-making processes required for effective performance on the IGT.
