New nonlinear interventional state space models identify neural dynamics

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new framework for identifying neural dynamics using nonlinear interventional state space models (iSSMs). This advancement extends previous iSSM capabilities beyond linear dynamics to a broader class of models, including those with general nonlinear dynamics. The team validated their theory on simulated FitzHugh-Nagumo dynamics and demonstrated its application in analyzing decision-making models and predicting neural responses to micro-stimulation in both macaque and human recordings. The research also offers practical guidance for designing stimulation protocols to enhance model identifiability. AI

IMPACT Introduces a more robust method for analyzing complex neural data, potentially improving AI's understanding of biological intelligence.

    Identifying Neural Dynamics Using Nonlinear Interventional State Space Models

    arXiv:2611.08113v1 Announce Type: new Abstract: State-space models (SSMs) recover low-dimensional latent dynamics from high-dimensional observations, but latents are generally not identifiable from observational data alone. Interventional state-space models (iSSMs) use perturbati…
