Understanding brain functions as those of dynamic networks

Functions of the human brain ranges from perception, motor control, cognition to communication. Since the discovery of Broca’s area in 1861, brain researches have been developed by localizing each individual function to a specific region in the brain. However, any function cannot be achieved by one localized area, each individual column, or a single neuron. Any function can only be achieved through dynamic collaboration across multiple “localized” areas in the brain. Dynamic Brain Network Laboratory aims at finding a principle of such collaboration across multiple regions, while the brain exerts an important function. Functions being studied are 1) 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 neurons in the precuneus whose receptive fields are fixed to the background in a scene.
  2. 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).
  3. We found that a heart rate increases momentarily after each spontaneous eyeblink (Nakano & Kuriyama, 2017).
What kind of background do your lab members have?
Members in our lab have a variety of backgrounds that range from neurophysiology, cognitive neuroscience to engineering.
Do you collaborate with institutions outside of Osaka Univ.?
We are collaborating with researchers in Johns Hopkins University, Lyon University, and so on.
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.
