Current models of the marmoset brain.

Area of Science:

• Neuroscience
• Primate Research
• Comparative Anatomy

Background:

• The common marmoset is increasingly used as a primate model in neuroscience.
• A reliable and detailed guide to marmoset brain structures is needed for research.
• Existing atlases may lack the detail or accessibility required for modern neuroscience techniques.

Purpose of the Study:

• To review the development of marmoset brain atlases.
• To introduce a newly developed, advanced 3D digital brain model for the common marmoset.
• To provide a resource for identifying brain structures in histological and imaging studies.

Main Methods:

• Review of existing marmoset brain atlas development.
• Reconstruction of a new brain model from histological sections using volume-rendering technology.
• Integration of nomenclatural annotations for in situ structure identification.

Main Results:

• A novel 3D digital common marmoset brain model has been created.
• The model allows for virtual sectioning along any plane.
• Nomenclatural annotations are provided for in situ identification of brain structures.
• The model is applicable for correlating with magnetic resonance imaging (MRI) data.

Conclusions:

• The new 3D digital brain model enhances the utility of the common marmoset as a neuroscience research model.
• This resource facilitates accurate identification of brain structures, aiding comparative neuroscience and anatomical studies.
• The model's accessibility and features support advanced research methodologies, including MRI-based investigations.
