Core Problem

Multi-compartment Hodgkin-Huxley (HH) models provide principled neural dynamics prediction but require invasive intracellular recordings for parameter fitting. This limits scalability to large neural populations and prevents capturing cell-specific properties in circuits.

Key Innovation

Framework to infer HH biophysical parameters from extracellular MEA (Multi-Electrode Array) measurements using:

  1. Differentiable biophysical simulation
  2. Simulation-based inference
  3. Designed features of extracellular signals

Methodology

Differentiable Biophysical Simulation

Extracellular MEA Data
        ↓
Feature Extraction (waveform shape, spike timing, etc.)
        ↓
Differentiable HH Model Simulation
        ↓
Gradient-Based Parameter Inference
        ↓
Predicted Biophysical Parameters

Key Components

  1. Feature Engineering: Extract informative features from extracellular recordings:

    • Extracellular waveform shapes
    • Spike timing patterns
    • Population activity features
  2. Differentiable Simulation: Make HH model differentiable to enable gradient-based optimization:

    • Backpropagation through biophysical equations
    • Efficient parameter updates
    • Scalable to large neuron populations
  3. Simulation-Based Inference: Use simulated data to train inference models:

    • Generate training data from known parameters
    • Learn mapping: features → biophysical parameters
    • Generalize to real experimental data

Applications

Predicting Neurostimulation Responses

Central translational neuroengineering goal: predict neural spiking responses to electrical stimulation

Use cases:

  • Optimize stimulation parameters for therapeutic effect
  • Minimize side effects by predicting off-target activation
  • Personalize deep brain stimulation (DBS) protocols
  • Design closed-loop stimulation systems

Large-Scale Circuit Modeling

  • Fit HH parameters for hundreds of neurons simultaneously
  • Capture cell-type specific properties
  • Build biologically realistic circuit models
  • Enable in-silico testing of interventions

Technical Advantages

Traditional Approach This Framework
Intracellular recordings (invasive) Extracellular MEA (scalable)
Single-cell fitting Population-scale inference
Manual parameter tuning Automated gradient-based optimization
Limited to simple models Full multi-compartment HH models

Implementation Notes

  • Simulation framework: Differentiable HH model
  • Inference method: Simulation-based inference with gradient optimization
  • Data source: High-density MEA recordings
  • Output: Biophysical parameters (conductances, time constants, morphology)

Validation

  • Predict spiking responses to electrical stimulation
  • Match experimental data from MEA recordings
  • Generalize across neurons and conditions
