Sector for Neuromodulation of Pathological Circuit
Research
Progressive cognitive decline associated with the formation of intraneuronal inclusions composed of aggregated proteins in neurons and glial cells is a common pathological hallmark of neurodegenerative disorders represented as Alzheimer’s disease. Although the overall mechanism underlying the disease progress is not fully understood, cumulative evidence indicates that the toxicity of aggregated proteins can trigger neuroinflammation, circuit dysfunction, and neuronal loss. So far, we have established multimodal neuroimaging methods that enable us to visualize the pathophysiological states of a mouse model for Alzheimer’s disease that could reproduce disease states of the human brain. In our research sector, utilizing these neuroimaging-based approaches, we aim to develop novel neuromodulation technologies to control the dysfunction of pathological circuits for realizing disease therapies in the future.
