Regularity and Structure of the Spatial Pattern of Blue Cones of Macaque Retina
研究了猕猴视网膜蓝锥细胞的空间排列规律，发现无序三角晶格、方晶格和硬球模型均无法拟合，而提出的弹性球模型能很好地匹配实际模式。
Abstract Models were developed for describing the regular pattern of blue cones in macaque retina. Two functional descriptions were applied to patterns, one based on the cdf of interpoint distances, the other on the cdf of the central angles of Voronoi regions. Disordered triangular and square lattices and hard balls failed to model the blue-cone point pattern. An elastic-ball model was developed whose spatial properties fit well those of the blue-cone pattern. This model employed a hard core and a soft surrounding shell and is proposed as a valid model for the blue-cone pattern.
