Tapping into Multi-Faceted Human Behavior and Psychopathology Using fMRI Brain Dynamics

Area of Science:

• Neuroscience
• Cognitive Science
• Psychiatry

Background:

• Human behavior is inherently dynamic, necessitating advanced methods to understand its neural basis.
• Time-resolved functional Magnetic Resonance Imaging (fMRI) has emerged as a key technique for quantifying neural dynamics.
• Existing analytical pipelines for dynamic fMRI are diverse, requiring conceptual organization.

Purpose of the Study:

• To provide a comprehensive overview of dynamic analytical pipelines for time-resolved fMRI.
• To synthesize observations on the application of these methods to behavior and brain disorders.
• To highlight inconsistencies and imbalances in the current use of dynamic fMRI approaches.

Main Methods:

• Conceptual organization of a broad repertoire of dynamic analytical pipelines for fMRI.
• Review of studies examining behavioral aspects with varying stability (e.g., physiological state, personality).
• Inclusion of selected brain disorders with genetic and symptomatic data.

Main Results:

• Limited consistency observed in dynamic findings across the literature.
• Unbalanced application of available analytical approaches, despite their potential for revealing distinct dynamic aspects.
• Identification of a gap between methodological diversity and consistent, comprehensive application.

Conclusions:

• Further comparative and collaborative research is needed to advance the field of dynamic fMRI.
• Standardization and broader application of diverse analytical techniques could yield richer insights.
• The review underscores the need for a more unified approach to studying neural dynamics of behavior.
