Topic: cell-type dynamical systems

Latent dynamical system (LDS) models have been widely used to characterize the dynamics of high-dimensional neural population activity. However, these models typically ignore the fact that the brain contains multiple cell types. This limits their ability to capture the functional roles of distinct cell classes, and thus to capture the effects of cell-specific optogenetic perturbations on neural activity and behavior. To address this gap, we introduce the "cell-type dynamical systems" (CTDS) model, which extends latent linear dynamical systems to contain distinct latent variables for each cell
