Background:

Navigating complex brain fiber tracts is challenging.
Current methods lack efficient exploration tools for anatomical and functional structures.

Purpose of the Study:

To develop a visual exploration paradigm for complex fiber tracts.
To improve navigation and selection of brain connectivity pathways.

Main Methods:

Combined traditional 3D streamtube models with 2D embeddings and hierarchical clustering trees.
Linked representations using interaction and perceptually uniform color spaces.
Conducted an anecdotal evaluation with neuroscientists.

Main Results:

The method facilitates navigation through complex fiber tract models.
