| Abstract(in English) | The retinal photoreceptor is a primary neuron in the visual system, which converts light signal into electrical signal. The intracellular calciurn system in the photoreceptor plays an important role to modulate the phototransduction mechanism and/or ionic current characteristics. In order to clarify the calcium mechanisms, we analyzed the spatio-temporal properties of the intracellular calcium in the photoreceptor by using a calcium imaging system. The results suggest that 1) at the resting state the outer segment of intracellular free Ca^<2+> level was higher than inner segmnet, which is resulted in cGMP activated channels of outer segment, 2) depo-larization of photoreceptor by high K^+ solution increased Ca^<2+> concentration of inner segment, which is generated by voltage activated Ca^<2+> channel. |
