Morphological Sholl analysis of mRGCs in PD and controls. a, b Comparison of terminal points number per cell in PD and controls considering total mRGC (a) or per cell type (b). c, d Comparison of the number of branch points in all mRCGs (c) and per cell type (d) in PD and controls. e, f Sholl area comparison of PD and control mRGCs globally (e) and per cell type (f). Data is presented as mean ± s.d. *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001. g Sholl analysis curve representing number of intersections per distance from soma, comparing total controls and PD mRGCs. Data is presented as mean ± s.e.m.
