Fig. 6: Spatial relationships between receptive and projective field.
a–c, Projective fields of three example groups. Left: ROI location mapping (cyan dots, release sites) relative to RFs (purple). Black indicates the RF envelope. Middle left: density of release sites. Middle right: histogram denoting orientation of ROI locations (140 G6, 254 G2 and 147 G4 ROIs; 17 retinae). Right: estimated RFs and projective fields (PFs). Dots indicate centroids. d, Relationship between RF area and PF area for 49 groups (color coded). Gray circles indicate RFs and PFs of glutamatergic groups (six ON and six OFF). Inset shows the ratio of PF area to RF area for amacrine cells (green; 49 groups and 17 retinae) and glutamatergic cells (gray; 12 groups and 8 retinae). e, Relationship between directional and orientational bias indexes (DBI and OBI, respectively) for projective fields. Gray circles show bipolar cells. Gray thick and dotted lines show 95% CIs. Inset shows example directionally (top, G15) and orientationally (bottom, G13) biased projective fields. f, Orientation relative to RF (angle) and extent of overlap between RF and PF. g, Relationship between overlap index (OLI) and size change index (SCI). Gray circles indicate glutamatergic cells. Inset shows RFs and PFs for three example groups. h, Angular tunings of projective fields for example orientationally (top) and directionally (bottom) biased groups. i, Top: angular tunings of projective fields for orientationally (left) and directionally (right) biased groups. Arrows represent tuning in each group. Bottom: histogram of preferred angles. j, Clustering of projective field properties. Magenta and yellow squares, directionally and orientationally biased groups, respectively. Boxes represent 25th to 75th percentiles and median; whiskers represent 1.5 × interquartile range.
