Abstract (in Japanese) (See Japanese page) 
(in English) We report an approach to estimate the functional connection from the possible anatomical connections and physiological response of each neuron. Male silkmoth is known for its programmed behavior for the pheromone orientation on the pheromone source detection. The action command is generated in the premotor center, composed of the lateral accessory lobe (LAL) and the ventral protocerebrum (VPC). The morphology and the physiological response to the pheromone stimulus are obtained for each main type of LAL-VPC neuron through the intensive electro-physiological and immunohistochemical experiments. However, how the motor command is generated in LAL-VPC, or the information pathway in the network, is still unknown. Therefore, the purpose of our study is to investigate the functional connection in LAL-VPC to elucidate the mechanism of the motor command generation based on the detailed experimental data on each neuron. The main pathway is extracted from the obtained connection, both by the connection strength and by the dynamics of the network simulation.
