A new study shows that the synaptically interconnected axon terminals of colour-sensitive fly photoreceptors that sample the same point in visual space receive additional inhibition from surrounding units; the resulting additional chromatic comparisons result in an optimal decorrelation of photoreceptor inputs. There are striking parallels between newly identified horizontal interactions and those mediated by mammalian horizontal cells.
一项新的研究表明，对视觉空间中同一点进行采样的、突触互联的感光器轴突末梢会从周围的单元接收额外的抑制；由此产生的额外的色觉对比导致了感光器输入的最佳去相关。新发现的水平细胞相互作用与哺乳动物水平细胞介导的相互作用之间存在惊人的相似之处。
