Elucidating the mechanisms of neuron-independent sleep/wakefulness regulation
The brain is composed of neurons, glial cells, and others. It is becoming clear that not only neurons but also glial cells play various roles in brain function. Recently, we have revealed that astrocyte activity changes dramatically in mice during the sleep/wakefulness state. In this project, we will examine whether artificially activating astrocytes by chemogenetics can affect sleep/wakefulness state and cortical oscillations, or in other words the causal relationship. This study will elucidate a neuron-independent mechanism of sleep/wakefulness regulation.


We spend a third of our lives asleep, yet we still do not know the answer to "Why do we sleep?" As a sleep researcher, my goal is to unravel the mysteries of sleep.
