A GEOMETRICAL DESCRIPTION OF HORIZONTAL CELL NETWORKS IN THE TURTLE RETINA

Networks of physiologically identified H2 horizontal cells in the turtle retina were labeled by intracellular injection of Neurobiotin. We obtained a quantitative description of the neighbourhood relations in the dye-coupled cell mosaics by using the somata as centers for the Voronoi-Delaunay construction. Computational models simulating the experimental data are presented.
