Summary
Macaque brain networks show organization homologous to humans, supporting their use as a model for studying brain connectivity and neurological diseases. This research aids in understanding brain function and dysfunction.
Area of Science:
- Neuroscience
- Systems Neuroscience
- Brain Imaging
Background:
- Altered large-scale brain network organization is observed in various diseases.
- Studying brain network mechanisms requires a homologous animal model for neurophysiological recordings and experimental manipulation.
Purpose of the Study:
- To comprehensively assess macaque resting-state networks.
- To determine the homology of macaque brain network organization with humans.
- To validate macaques as a model for studying brain connectivity.
Main Methods:
- Utilized resting-state functional magnetic resonance imaging (fMRI) data.
- Analyzed intrinsic low-frequency fluctuations of the blood oxygen-level-dependent (BOLD) signal.
- Applied group independent component analysis (ICA) to identify brain networks.
Main Results:
- Identified macaque resting-state networks involved in sensory, motor, and cognitive processing.
- Demonstrated remarkable homology between macaque and human large-scale brain network organization.
- Found that macaques possess homologous network organization to humans.
Conclusions:
- Macaque brain network organization is highly homologous to humans.
- Macaques serve as a valuable animal model for studying normal and abnormal brain connectivity.
- This model aids in interpreting electrophysiological recordings within the context of large-scale brain networks.
