New framework infers canonical computations from brain activity

Researchers have developed a new mathematical framework to identify canonical distributed computations within the brain. This approach integrates normative and algorithmic theories, hypothesizing that the brain learns an internal model of its environment and uses a nonlinear message-passing algorithm for inference. The framework aims to uncover neural representations of latent variables, their interactions, and the inference algorithm itself, by analyzing large-scale neural activity patterns. Demonstrations using simulated neural recordings successfully recovered these computational elements, highlighting experimental design needs for extracting such computations from real brain data. AI

    Inferring Inference

    arXiv:2310.03186v4 Announce Type: replace-cross Abstract: Patterns of microcircuitry in the cerebral cortex suggest that the brain has an array of repeated canonical computational units. However, neural representations are distributed, so the relevant computations may only be rel…
