Latent Variable Modeling of Neural Population Dynamics

  • Zhe Chen

Abstract

Neural activity is noisy (“stochastic”) and dynamic at various spatiotemporal scales. We consider a general class of latent variable models for characterizing neuronal population dynamics or analyzing various sorts of neural data. The inference of latent variable models can lead to novel solutions for signal detection, neural decoding, denoising, dimensionality reduction, and data visualization. We review general modeling and inference strategies for latent variable models. Finally, we illustrate our methods with several neuroscience applications using population spike trains recorded from the animal’s hippocampus and neocortices.
