Neural characterization in partially observed populations of spiking
... Here we extend the point-process modeling framework to incorporate a set of unobserved or “hidden” neurons, whose spike trains are unknown and treated as hidden or latent variables. The unobserved neurons respond to the stimulus and to synaptic inputs from other neurons, and their spiking activity ...
