Connectivity Results
Analysis complete: Showing projection strengths from to other brain regions.
Bar Chart: Shows the projection strength from to various target regions. Higher bars indicate stronger connections.
Heatmap: Visualizes the connectivity strength using color intensity. Darker red indicates stronger projections from to the target region.
Network Graph: Displays a network representation of brain connectivity. The bright pink node is , bright blue nodes are target regions, and thicker lines indicate stronger connections.

Understanding the Data

This application visualizes neuronal connectivity data from the Allen Mouse Brain Connectivity Atlas. The data shows how strongly different brain regions are connected to each other.

Interpreting the results:
  • Projection Strength: Measures how strongly neurons from the source region project to other regions. Higher values indicate stronger connections.
  • Source Region: The brain structure you selected with the ID number.
  • Target Regions: Other brain areas that receive connections from your selected source region.
Example Interpretation
  • If you enter Structure ID 385 (Primary Visual Area), and the thalamus has a high projection strength, this means: "The Primary Visual Area sends strong connections to the thalamus."
  • If the Cerebellum has a lower projection strength, it means: "The Primary Visual Area has weak or no direct connections to the Cerebellum."

Scientific context: Understanding these connections helps neuroscientists map information flow in the brain and can inform research on neural circuits, behavior, and brain disorders.

About AI Features

This application uses AI to enhance your exploration of brain connectivity data:
