Anatomy of the Brain: Major Regions

Anatomy of the Brain: Major Regions

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...

Area of Science:

Neuroscience
Comparative Anatomy
Neuroimaging

Background:

Previous single-subject atlases for the common marmoset brain (Callithrix jacchus) exhibit structural biases due to individual variations.
A generalized, population-based atlas is needed to overcome these limitations and facilitate broader research applications.

Purpose of the Study:

To introduce Brain/MINDS 3D digital marmoset brain atlas version 2.0 (BMA2.0), a population-based resource.
To provide a comprehensive, generalized whole-brain parcellation for the common marmoset.
To facilitate multimodal data analysis and integration in marmoset neuroscience.

Main Methods:

Manual delineation of cortical regions from 10 myelin-stained brains for generalized parcellation.
Incorporation of refined subcortical regions and a new cerebellum parcellation.
Co-registration of average templates for myelin, Nissl, ex vivo MRI T2, and in vivo MRI T2 data from multiple individuals.

Main Results:

BMA2.0 provides a comprehensive, population-based 3D digital brain atlas for the common marmoset.
Includes generalized cortical, refined subcortical, and novel cerebellum parcellations for both hemispheres.
Offers co-registered multimodal imaging templates (myelin, Nissl, MRI T2) and surface reconstructions.

Conclusions:

BMA2.0 serves as a central brain space for multimodal data integration, spatial analysis, and comparative neuroscience.
The atlas facilitates interoperability with existing workflows and atlases through standard formats and transformations.
This resource enhances the study of the common marmoset brain, a valuable model organism.
