Outline of Final Research Achievements

Behavioral change was analyzed which depend on establishment of learning on spatial navigation task. After established spatial learning, monkeys might used distal spatial cues to estimate their own location and reward areas. Place-selective neuronal activity was observed from monkey retrosplenial cortex during spatial navigation task. These neuronal activity was reduced by added or removed distal spatial cues, and not responded to novel environment. These results suggest that retrosplenial neuron has a function of memory retention or retrieval about spatial information.
