| Outline of Final Research Achievements |
What is drowsiness? The true nature of drowsiness has not been clarified. We hypothesized that sleepiness is encoded by changes in neuronal activity in specific regions/neurons in the brain, and attempted to identify these neurons by histological methods. We also hypothesized that some of the specific regions and neurons in the brain involved in the loss of consciousness during general anesthesia are involved in sleep induction, and we searched for such neurons. To further investigate the true nature of drowsiness, we tested whether postprandial sleepiness can be artificially induced in experimental animals (mice).
