Abstract:
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.
