Functional Integration Between the Two Brain Hemispheres: Evidence From the Homotopic Functional Connectivity Under...

Area of Science:

• Neuroscience
• Cognitive Neuroscience
• Brain Imaging

Background:

• Neural integration is key to brain organization.
• Interhemispheric functional integration is crucial for human cognition.
• Resting-state functional connectivity (rs-FC) examines neural communication.

Purpose of the Study:

• To review progress in homotopic functional connectivity (HoFC) studies.
• To highlight how HoFC enhances understanding of interhemispheric organization.
• To explore the role of interhemispheric interactions in cognition.

Main Methods:

• Review of existing literature on resting-state homotopic functional connectivity (HoFC).
• Analysis of how HoFC studies contribute to understanding brain organization.
• Synthesis of findings on interhemispheric functional integration.

Main Results:

• HoFC studies provide insights into brain organization.
• Resting-state HoFC reveals functional integration between brain hemispheres.
• Understanding interhemispheric interactions is advancing through HoFC research.

Conclusions:

• HoFC is a valuable tool for studying interhemispheric communication.
• Further research is needed on methodological issues, behavioral links, disease modulation, task effects, and genetic basis of HoFC.
• HoFC research significantly enhances understanding of human brain organization.
