Summary
The human and macaque brains share similar overall wiring, with key differences found in cingulate regions. This study reveals a common structural backbone, crucial for brain-wide information transfer, highlighting evolutionary conservation in primate brain networks.
Area of Science:
- Neuroscience
- Comparative Anatomy
- Evolutionary Biology
Background:
- The macaque brain is a model for the human brain.
- Human evolution introduced unique features, including connectivity reconfigurations.
- Understanding these differences is crucial for translational research.
Purpose of the Study:
- To quantitatively compare the whole brain macroscale structural connectivity between humans and macaques.
- To identify similarities and differences in brain wiring.
- To explore evolutionary aspects of primate brain connectivity.
Main Methods:
- Quantitative comparative analysis of whole brain macroscale structural connectivity.
- Region-wise analysis of connectivity patterns.
Main Results:
- The human and macaque brains exhibit similar overall wiring.
- Many interspecies similarities in connectivity patterns were observed.
- Differences were primarily noted in cingulate regions.
- A common structural backbone, involving overlapping regions, was identified in both species.
Conclusions:
- The structural backbone is a conserved feature of primate brain evolution.
- Findings provide a quantitative bridge between macaque and human research.
- Novel evolutionary insights at the macroscale connectivity level were revealed.

The brain is the most complex organ in the human body. It consists of four main parts: the cerebrum, diencephalon, cerebellum, and brainstem.
The cerebrum is the largest section of the brain and divides into left and right hemispheres, separated by a deep fissure. The cerebral outer layer of grey matter — the cerebral cortex — comprises elevations called gyri and shallow groves called sulci. The inner portion of white matter includes long nerve fibers known as axons, which connect...

The brain is an integral component of the nervous system and serves as the center for processing sensory inputs, making decisions, and directing bodily actions. This complex organ is organized into three primary sections: the hindbrain, midbrain, and forebrain, each responsible for a range of vital functions.
Hindbrain
The hindbrain, located at the base of the brain, plays a vital role in regulating automatic processes that sustain life. It includes the medulla oblongata, which is essential for...
