Polyak is a major authority on the anatomy and neural organization of the primate eye. Midget cells in the central retina were recognized by their extremely small dendritic trees, approximately microns in diameter.

Zic2 will promote the expression of the tyrosine kinase receptor EphB1, which, through forward signaling see review by Xu et al. Ninety of these cells were cut from their retinas, embedded in methacrylate, and transversely sectioned.
Very recent evidence from the same group Crook et al. The opponent color surrounds recorded in midget ganglion cells 28 provide color and spatial opponency. The model consisted of the product of three profiles: The situation is different in primate retina where color opponency has been difficult to detect in intracellular recordings of monkey horizontal cells Dacey et al.
These glia will secrete repulsive Semaphorin 5a and Slit in a surround fashion, covering the optic nerve which ensures that they remain in the optic nerve. Results Receptive field mosaics of parasol and midget cells Light responses of hundreds of retinal ganglion cells were simultaneously recorded in isolated segments of macaque monkey retina. They appear to play a role in defining the ipsilateral projection by altering expression of Zic2 and EphB1 receptor production. Kolb H, DeKorver L.
