Area of Science:

  • Neuroscience
  • Digital Anatomy
  • Medical Imaging

Background:

  • Accurate 3D neuroanatomical atlases are crucial for brain research.
  • Existing rat brain atlases may lack integrated, high-resolution representations.

Purpose of the Study:

  • To develop a comprehensive, three-dimensional (3D) digital atlas of Sprague-Dawley rat brain anatomy.
  • To provide researchers with an integrated, interactive neuroanatomical resource.

Main Methods:

  • Digital cryosectional imaging of six male Sprague-Dawley rat brains.
  • Image registration and volume reconstruction to create a representative 3D digital volume.
  • Transformation into a common coordinate system using key anatomical landmarks.

Main Results:

  • A high-resolution 3D digital map of rat brain neuroanatomy was generated.
  • The atlas includes sagittal, coronal, and horizontal planes with stereotaxic reference grids.
  • Anatomical features are identified with stylized boundaries and labels.

Conclusions:

  • The developed 3D digital rat brain atlas provides an integrated in situ neuroanatomical representation.
  • This resource is publicly accessible via the internet (FTP and WWW) for enhanced research collaboration.
  • Digital format facilitates electronic sharing and interactive use, advancing neuroscience research.
