Comparative studies of sensory information processing in visual, mechano-sensitive and chemo-sensitive systems were carried out at various levels from sensory cells to higher-order interneurons. The results obtained are as follows: 1) The structure of subrahbdomeric cisternae is a significant structure for the maintenance of the structure of photoreceptive membrane. 2) The ratio of 3-dehydroretinal/retinal as visual pigment chromophore depends on visual environment and diurnal rhythm. 3) There are five types of visual cells in the retina of the cabbage butterfly: among them red and UV visual cells are long visual cells terminating on the medulla. 4) Two extracellular photoreceptors (A-P-1 and A-P-2) have an ability for wave-length discrimination, and they are connected mutually through inhibitory synapses. 5) Ca 21 plays a significant role in generating the electrical responses in visual cells of the octopus. 6) In the cockroach ocellar system, the candidate of transmitter released fro … More m photoreceptor cells may be GABA, and the light signals, which enter the 3rd-order interneurons from the 2nd-order interneurons, are passed through a non-linear filter. 7).In the spider, the effects of efferent neurons running through the optic nerve on visual cells differ with the eyes. 8) In the crayfish brain, the nonspiking giant interneurons respond to geotactic inputs as well as to visual inputs, and they are presynaptic to some of the oculomotor neurons. 9) In the fly, the development of visual pattern discrimination is strongly influenced by visual experience and neural activity in the early stage of post-emergence, and this may be related to the modification of synaptic connection, which accompanies molecular changes. 10) The resolution of the circadian rhythm in visual interneurons of crickets involves the oscillators in the neighborhood of the medulla. 11) In the cricket terminal abdominal ganglion, a local circuit relating functionally to the cercus-to-giant interneuron system has a plasticity responsible for depriving the sensory inputs from one of the cerci. 12) In the crayfish, the proprioabdominal interneurons play an important role in the interation of information from the descending statocyst pathway and the abdominal posture system. 13) In several insects, morphological and physiological properties of many types of intrisic neurons transmitting chemical information were elucidated in the protocerebrum and mushroom body. 14) The spike discharges were recorded from the tarsus sugar receptors in Drosophila, and quantitative behavioral analysis of food seraciting behavior in response to sugar were carried out using an automatic recording system for the searching believer.

在从感觉细胞到高阶中间神经元的各个层面上进行了视觉、机械敏感和化学敏感系统中感觉信息处理的比较研究。获得的结果如下： 1)亚臂池结构是维持感光膜结构的重要结构。 2）作为视觉色素发色团的3-脱氢视网膜/视网膜的比例取决于视觉环境和昼夜节律。 3）菜粉蝶的视网膜中有五种视觉细胞：其中红视觉细胞和紫外视觉细胞是终止于髓质的长视觉细胞。 4）两个细胞外光感受器（A-P-1和A-P-2）具有波长辨别能力，它们通过抑制性突触相互连接。 5) Ca 21 在章鱼视细胞产生电反应方面发挥着重要作用。 6）在蟑螂眼细胞系统中，光感受器细胞释放的候选递质可能是GABA，光信号从二阶中间神经元进入三阶中间神经元，通过非线性滤波器。 7).在蜘蛛中，穿过视神经的传出神经元对视觉细胞的影响因眼睛而异。 8）在小龙虾大脑中，非尖峰巨型中间神经元对地向输入和视觉输入做出反应，并且它们位于一些动眼神经元的突触前。 9）在果蝇中，视觉模式辨别的发展受到羽化后早期视觉体验和神经活动的强烈影响，这可能与伴随分子变化的突触连接的改变有关。 10）蟋蟀视觉中间神经元昼夜节律的分辨率涉及髓质附近的振荡器。 11）在蟋蟀末端腹部神经节中，与尾叶到巨型中间神经元系统功能相关的局部回路具有可塑性，负责剥夺尾叶之一的感觉输入。 12）在小龙虾中，本体腹部中间神经元在来自下行静态囊通路和腹部姿势系统的信息交互中发挥重要作用。 13）在几种昆虫中，许多类型的内在神经元传递化学信息的形态和生理特性在原大脑和蘑菇体中得到了阐明。 14) 记录果蝇跗节糖受体的尖峰放电，并使用搜索信徒的自动记录系统对响应糖的食物丝氨酸行为进行定量行为分析。较少的
