Yoshimura Lab
Machine-translated · View original
The lab studies brain–machine interfaces that read information from the brain using EEG and fMRI.

AboutAbout the lab
Decoding, visualizing, maintaining, and improving brain function.
The Yoshimura Lab studies how to read information from brain activity signals that can be measured without harming the body, such as EEG and fMRI.
Based on the information it reads, the lab builds brain–machine interfaces (BMIs) that connect the brain to machines.
The lab decodes motor control, hearing and speech, and emotion, using machine learning to extract information from the signals.
As an international collaboration, it is also developing BMIs for people who cannot move their bodies because of amyotrophic lateral sclerosis (ALS).
Key terms
- EEG
- Weak electrical changes that accompany brain activity, measured with electrodes placed on the head
- fMRI
- A method that uses magnetism to find out which parts of the brain are active, from changes in blood flow
- Brain–machine interface
- A mechanism that reads brain activity signals and directly operates a machine or computer

The lab studies how to extract information from inside the brain using noninvasive brain activity signals such as EEG and fMRI together with machine learning. Through brain information decoding and mechanisms that feed the results back to the user, the lab aims to build brain–machine interfaces that maintain and enhance the functioning of the human mind and body.
*Illustrative imageDecoding Hearing and Speech
From EEG, the lab reads what sounds a person heard and what they imagined, and investigates where in the brain that information is processed. It has also shown the possibility of reproducing heard or recalled sounds as actual sound.
Decoding Movement Information
The lab reads movement-related information from EEG and fMRI. It has built up results that lead to brain–machine interfaces and to an understanding of motor control mechanisms, such as driving a power-assist robot with muscle activity signals estimated from EEG.
*Illustrative imageDecoding Emotion Information
This work uses EEG to read emotional information. The lab has shown that it may be possible to extract from EEG the frustration that arises while operating a computer cursor, and has shown a method for predicting the intensity of emotion from independent components of EEG.
MembersFaculty
