# Neural Decoding **Domain:** Computational Neuroscience / Machine Learning **Doc Type:** Concept Node **Maturity:** Active Research and Deployment **Related:** [[Neural Signal Acquisition]], [[Generative BCI Decoding]], [[Brain-Computer Interfaces]], [[Neural Data Provenance]] --- ## Definition **Neural decoding** estimates an intended action, stimulus, linguistic unit, perceptual category, or internal state from measured neural activity. A decoder is a model conditioned by its sensor modality, task, training data, temporal window, preprocessing, and target representation. ## Evidentiary boundary Decoded output is an inference, not a transparent copy of thought. Accuracy depends on the experimental distribution and may not generalize across people, devices, sessions, or contexts without calibration.
