Structured Bayesian Modeling of Dynamic Receptive1 Fields in Salamander Retinal Ganglion Cells

Neurons in the visual system are selective for specific spatial and temporal stimulus features, described by their \emph{receptive field}. Estimating one means a coefficient per pixel per time bin from few trials -- a high-dimensional problem requiring regularization. Sparse regularizers such as the LASSO handle the di...
