Understanding brain functions as those of dynamic networks
Functions of the human brain ranges from perception, motor control, and cognition, to communication. Since the discovery of Broca’s area in 1861, brain researches has been developed by localizing each individual function to a specific region in the brain. However, any function cannot be achieved in one localized area, each individual column, or single neuron. Functions can only be achieved through dynamic collaboration across multiple “localized” areas of the brain. Our Dynamic Brain Network Laboratory aims at finding the principle of such collaboration across multiple regions. Functions being studied are 1) the perception of time, 2) motor learning, 3) visual stability, and 4) social communication.

Q＆A
- What is your hot research topic?
- We are now interested in elucidating the functions of the precuneus. The precuneus, the core region of the default mode network, is likely to represent the origin of our space and time perception (the here and now). The default mode network, which was found to be activated after each eyeblink, occupies the center of the brain network.
- What is your breakthrough or research progress in the last 5 years?
- 1. We found that “the now” is represented in the precuneus (Tang et al., 2021).
2. We found that the dopamine reward sys
3. We found that neurons in the motor and parietal association cortices detect errors in reaching, and provide instructions on how to improve the movement (Inoue et al., 2016, 2018).
- What kind of background do your lab members have？
- Members in our lab have a variety of backgrounds that range from neurophysiology to cognitive neuroscience and engineering.
- Do you collaborate with other institutions and universities?
- We are collaborating with researchers at Johns Hopkins University, Lyon University, and others.
- What kind of careers do your Lab's alumni go on to?
- Some assume positions in universities, research institutes, hospitals, and others in companies.
- How do you develop your research?
- It is generally accepted that amyloid beta deposits begin to accumulate in the precuneus and the default mode network before the onset of Alzheimer's dementia. Our research on cognitive functions and the brain network will provide significant clues to understand pathophysiology of dementia.
