在果蝇视觉系统的两种运动敏感神经元中，我们分析了树突几何结构对突触信息处理的影响。这些神经元在树突的形态上有明显的不同，但它们从相同类型的局部运动敏感元件接收输入。细胞内记录和通过视觉运动激活树突的选定区域表明，根据神经细胞的电缆理论，突触后信号相互作用的方式本质上是由树突树的结构决定的。
THE consequences of dendritic geometry for the processing of synaptic information was analysed in two types of motion-sensitive neurones in the visual system of the fly. These neurones differ conspicuously in the morphology of their dendrites but receive their input from the same type of local motion-sensitive elements. Intracellular recording and activating selected regions of the dendrite by visual motion showed that, in accordance with cable theory of nerve cells, the way in which postsynaptic signals interact is essentially determined by the structure of the dendritic tree.
