Brain Imaging

Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic Stimulation (TMS).

Area of Science:

Neuroscience
Comparative Anatomy
Medical Imaging

Background:

Reconstructing highly gyrified brains, like those of dolphins and pinnipeds, presents significant challenges in neuroanatomy.
Accurate brain surface reconstruction is crucial for understanding brain structure and function.

Purpose of the Study:

To introduce Stitcher, a novel computational tool for generating 3D brain surface reconstructions from MRI data.
To validate Stitcher's efficacy on complex brains of non-primate species, including dolphins and a pinniped.
To assess the accuracy and utility of Stitcher for neuroanatomical analysis and comparative studies.

Main Methods:

Stitcher utilizes MRI data and manual segmentation to create triangulated cortical surfaces.
The algorithm recursively adds edges to segmentations, minimizing total edge length and preventing self-intersection.
The method was applied to Guiana dolphin (Sotalia guianensis), Franciscana dolphin (Pontoporia blainvillei), and Steller sea lion (Eumetopias jubatus), including sub-cortical structures.

Main Results:

Stitcher successfully generated high-fidelity cortical surface reconstructions for dolphins and Steller sea lions, closely matching real brain anatomy.
Reconstructions of sub-cortical and non-cortical structures were accurate, preserving spatial relationships.
Volumetric measurements from Stitcher reconstructions showed compatibility with established anatomical tools.

Conclusions:

Stitcher is a viable tool for neuroanatomical analysis, particularly for complex, non-primate brains.
The software enhances the visualization and description of brain structures, broadening the scope of comparative neuroanatomy.
Stitcher facilitates detailed mapping of brain anatomy, aiding future research in marine mammal and pinniped neuroscience.
