Axon models
OSS-DBSv2 supports pathway-based analyses in which extracellular fields are sampled along trajectories and then coupled to axon models. This extends the workflow beyond field simulation toward estimates of neural pathway activation.
Workflow overview
A typical pathway-based workflow consists of:
generating or importing pathway trajectories
evaluating the extracellular solution along those pathways
mapping the sampled signal to a neuron model
computing activation-related outputs
This part of the software is more specialized than the basic volume conductor workflow, but it becomes essential when the scientific question focuses on which pathways are activated rather than only how far the field spreads.
Implemented model families
The codebase includes morphology handling for models such as MRG2002 and McNeal1976, together with a neuron-simulation abstraction for running pathway activation analyses.
When to use this part of the toolbox
use it when tract-based activation is a central study outcome
skip it for a first validation run focused only on electric fields or basic VTA-like analyses
treat it as a separate workflow layer that builds on a correct and stable volume conductor setup
