| Abstract |
The dorsal inner plexiform layer in the retina of Callionymus lyra consists of successive fibrous F layers and geometrically organized P layers. In the F layers no pattern arrangement of the bipolar synaptic buttons was observed. In the P layers, on the contrary, the bipolar synaptic buttons are grouped by three distinct square patterns. The α pattern measures 5 μm and corresponds to the square pattern of the photoreceptor cells. The gβ and the γ pattern measure 7 μm. One of both patterns corresponds to the single cone arrangement, while the other coincides with the crossings of the rows of double cone pairs. The alternation of F and P layers results in the stratified appearance of the inner plexiform layer. |
