Learning Graph Viewer¶
Open Learning Graph Viewer Fullscreen (recommended)
This interactive viewer lets you explore the learning graph for From Neuron to Bedside: 253 concepts, from the cell membrane to the neurological exam, and the prerequisite arrows that connect them.
Categories¶
Each node is colored by its category in the concept taxonomy:
| Color | Category | Code |
|---|---|---|
| Steel blue | Foundational Biology and Chemistry | FOUND |
| Dark green | Neurons and Glia | CELL |
| Gold | Electrical and Chemical Signaling | SIG |
| Teal | Neuroanatomy | ANAT |
| Orange | Sensory Systems and Pain | SENS |
| Dark slate blue | Movement and Motor Control | MOTOR |
| Lime green | Development and Aging | DEV |
| Dark orchid | Learning, Memory, and Cognition | COG |
| Light sky blue | Sleep, Emotion, and Stress | STATE |
| Crimson | Disorders and Diseases | DIS |
| Hot pink | Clinical Exam, Imaging, and Treatment | CLIN |
| Saddle brown | Research Methods and Careers | RES |
Larger boxes are concepts that more of the book builds on (a higher Concept Impact Score). Foundational concepts are the ones with no outgoing arrows.
Features¶
- Search: Type in the search box to find specific concepts
- Category Filtering: Use checkboxes to show/hide concept categories
- Interactive Navigation: Click and drag to explore, scroll to zoom
- Statistics: View real-time counts of visible nodes and edges
Using the Viewer¶
-
Search for Concepts: Start typing in the search box to find concepts. Click on a result to focus on that node.
-
Filter by Category: Use the category checkboxes in the sidebar to show or hide groups of related concepts. Use "Check All" or "Uncheck All" for bulk operations.
-
Navigate the Graph:
- Drag to pan around the graph
- Scroll to zoom in and out
- Click on a node to select it and highlight its connections
- Click the hamburger menu to collapse or expand the sidebar
-
View Statistics: The sidebar shows counts of visible nodes, edges, and foundational concepts.
Graph Structure¶
- Foundational Concepts: Prerequisites with no dependencies
- Advanced Concepts: Topics that build on multiple prerequisites
- Edges: Arrows point from a concept to its prerequisites
The graph uses a force-directed layout that positions related concepts near each other.
