Applying Super-Resolution and Tomography Concepts to Identify Receptive Field Subunits in the Retina

Shortcomings of FBP as a reconstruction method for subunit layouts.
(A) Sample stimuli of a vertical (left) and a horizontal (right) Ricker stripe hitting the center of an exemplary elliptical subunit (here in green). (B) Rate responses of a model consisting of only that one subunit depicted as a sinogram. (C) Resulting reconstruction via FBP from the sinogram in (B). Red denotes positive values, blue negative values.
