Figure 2b

Figure 2b. Cone contacts of H1, H2 and H3 horizontal cell types in zebrafish retina (A, B, C respectively). These neurons were back-labeled with DiI through crystals placed on their axons. Dendritic tips and spines contact cones, sometimes in clusters called ‘rosettes’. D. Zebrafish cones form a regular mosaic of red (R), green (G), blue (B) and ultraviolet (UV) types. The position of horizontal-cell contacts within the mosaic identifies the cone color type that is contacted. E. Summary of cone contacts for H1, H2 and H3 types. Black arrows are contacts proposed for feed-forward excitation, while gray arrows are contacts proposed for feedback inhibition. Except for the UV triphasic H3 cell, all horizontal cells are excited by 2 cone types. The figure is from Li, et al, 2009 (37), with physiological identifications based on Connaughton and Nelson, 2010 (6).
