Conducting Basic Research Basic research in bioscience is carried out by five research departments. Research of Laboratory of Systems Biology are directed toward molecular and systems mechanisms of brain function and dysfunction, focusing on mechanisms of motor balance, reward-based and aversive learning, Parkinson's disease and drug addiction in the basal ganglia network and those of motor coordination and learning in the cerebellar network. Cell Biology Department investigates epigenetic regulation of neuronal circuits and functions. These researches may lead to understand how environmental factors induce human neuronal diseases. The Molecular Behavioral Biology Department studies the mechanism of sleep-wake regulation, sleep-wake being the basic phenomenon observed in all organisms with the aim of helping overcome sleep disorders and develop sleep regulators without adverse reactions. The Functional Neuroscience Department studies the mechanisms to regulate specific emotions and behaviors in the mammalian brain using combination of molecular biology, anatomy, biochemistry, physiology and behavioral research methods to establish new insight into understanding the mind of human and animals. The primary goal of the research activities for the Developmental Biology Department is to elucidate the mechanism of retinal development to compile basic data that may lead to the treatment of blindness.
