NeuralManifoldDynamics: A Versioned Measurement Contract for Low-Dimensional Neural-Manifold Trajectories

NeuralManifoldDynamics defines a versioned ingest-layer measurement contract for deriving canonical 3D neural-manifold trajectories, stratified 9D coordinates, and local Jacobian-based dynamical summaries from (i)EEG, fMRI and MEG (beta version). The system emphasizes determinist...

Region-specific neural manifold dynamics along a standardised visual-hippocampal-thalamic recording axis: a multi-lab IBL Reproducible Ephys study

The IBL Reproducible Ephys project asked whether different neuroscience laboratories can reliably record from the same brain circuits. We ask a complementary question: does the geometry of neural population dynamics reproduce across laboratories? Using a framework called Noetic D...

Estimator quality and anatomical matching constrain cross-cohort neural manifold flow inference: a case study in two IBL Neuropixels datasets

We apply a new mathematical framework - Noetic Diffusion Theory (NDT) - to two large publicly available rodent electrophysiology datasets from the International Brain Laboratory, and attempt to test whether a discovery effect survives a structured external portability audit. An a...
