Quantitative understanding of the human brain

We aim to understand the neural basis underlying diverse perceptual and cognitive functions in the human brain. More specifically, our research focuses on understanding neural processing and representation by building predictive models of brain activity evoked under natural perceptual and cognitive conditions. Using such models, we also aim to develop quantitative bases for decoding brain activity as a medium for communications.

Schematics of our approach. We record brain activity evoked by natural perceptual and cognitive experiences and build predictive models. By analyzing the models, we aim at understanding information processing and representation in the brain.

Q＆A

What is your hot research topic?
Recent development in machine learning techniques, including deep learning and natural language processing, allow us to build more accurate predictive models of brain activity. Using such technologies, we aim to acquire new quantitative knowledge and interpretations on information processing and representation in the brain.
What kind of background do your lab members have？
Our research members (FBS/NICT) have diverse backgrounds, including biophysics, neurophysiology, computer science, psychology, and art.
Do you collaborate with other institutions and universities?
We are collaborating with NICT CiNet (close relation with Osaka University CiNet), University of Tokyo (JST ERATO/Mirai Program), and other research institutes.
