Research Projects
1. State-dependent auditory processing and perception
When we are paying attention to sound, we can vividly perceive it. When sleep, however, our perception is siginificantly diminished. But what is happening in the brain? Because our brain activity ('brain state') continuously changes, it is extremely important to address the following three questions: 1) how is each brain state organized at the level of neural circuit? 2) how do brain states affect sensory processing and perceptual decision? and 3) how are brain states regulated? We are addressing these questions by taking multidisciplinary approaches, with a focus on dynamic interplays between the auditory system and neuromodulatory systems.

2. The circuit mechanism of abnormal hearing
Brain circuits often generate auditory perception even in the absence of auditory inputs, such as auditory hallucinations. But how? We are particularly focusing on phantom auditory perception, so-called tinnitus. Tinnitus is a symptom, which is often associated with hearing loss. Considering aging society and age-related hearing loss, a better understanding of the neural basis of tinnitus is extremly urgent. We are aiming to identify neural correlates of tinnitus at the level of neuronal circuits. By using a massively parallel extracellular recording technique and a behavioural approach, we are determining relationships between tinnitus and abnormal neural population activity in the auditory thalamocortical circuit. This research program will provide further insight into the development of new treatment for tinnitus sufferers.

3. Technology development to improve and restore hearing
Once we understand both normal and abnormal states, a next step is to explore strategies to restore abnormal states into the normal one. In addition, we can also think of how we can boost our normal brain functions. To achieve these goals, we are developing new approaches and technologies. We are particularly interested in the improvement and restoration of sensory abilities by controlling neural activity. Combining advanced technologies in rodents as a model, we are developing novel strategies to improve and restore hearing.
