Brain Navi^TM captures brain responses to stimuli

Spontaneous brainwaves and evoked brainwaves

Types of brainwaves and brainwaves that Brain Navi^TM can measure

Brainwaves can be broadly classified into two types: spontaneous brainwaves, which constantly occur, and evoked brainwaves, which appear in response to stimuli. Murata Manufacturing's Brain Navi^TM was developed with a focus on evoked brainwaves, and particularly ERPs that capture brain responses to stimuli.

Event-related potentials (ERPs) that can be measured by Brain Navi^TM

When the brain recognizes stimuli such as sound or light, weak electrical signals are generated simultaneously on the surface of the head. ERPs are representations of the fluctuations in that potential.

Brain Navi^TM leverages Murata Manufacturing's advanced sensing and analysis technologies to easily measure and visualize not only spontaneous brainwaves but also evoked brainwaves and ERPs, providing new possibilities for business.

What are ERPs?

Highly precise synchronization of stimuli and brain response timing

Conventional EEG measurements record the overall activity of the brain, and are thus not suited to measuring brain responses to specific stimuli. Brain Navi^TM is capable of measuring ERPs, so the stimulus presentation and EEG measurement timings can be synchronized with high precision, enabling visualization of brainwave changes the instant that the brain responds to stimuli.

This technology makes it possible to obtain data on brain responses to human senses and cognition such as seeing and hearing. Currently, Brain Navi^TM measurement methods have been established for visual and auditory stimuli, and technical development is also underway for touch, smell, and taste.

Accurate and objective data that does not rely on subjectivity

ERPs are indicators that represent how the brain perceives and processes stimuli, and are gaining attention as a more accurate and objective means of evaluation compared to conventional subjective responses. As long as the brain responds, changes in potential can be captured, even for information we do not notice or stimuli that we feel we do not remember. This enables use even for evaluation of latent cognition and impressions.
A wide range of applications are anticipated, such as evaluation of responses to products and advertising, improvement of user interfaces, and early detection of changes in cognitive functions due to fatigue and aging.

A simple device with no need for a large-scale measurement environment

Brain Navi^TM is an innovative brainwave analysis service that achieves simple and high-precision measurement and analysis of characteristics such as spontaneous brainwaves as well as ERPs that were previously challenging without specialized facilities.

There is no need for a sheilded room, the conventional measurement setting, large-scale measurement equipment, or challenging conductive gel. The measurement device is a single-electrode, headphone-type device that is comfortable enough for daily use, minimizing discomfort for users.

Murata's strengths lie in high precision and wireless technologies

Brain Navi^TM combines a noise-reducing circuit design with an advanced noise rejection algorithm to accurately capture even weak brainwave signals. It also makes use of Murata Manufacturing's unique IP-based synchronization technology developed over many years to synchronize the time axes of the stimulus presentation and the brainwave data with millisecond accuracy, achieving a high-precision measurement environment. This provides ERP measurements with accuracy comparable to medical research levels, using a less expensive and more compact device.

Utilization of ERPs requires experimental designs based on specialized knowledge such as stimulus (event) design and data analysis. However, Murata will accompany you as a partner from introduction to implementation and analysis support. Brain Navi^TM, which visualizes brain responses, will surely be a powerful ally in new product development and service enhancement.

Fields where Brain Navi^TM is anticipated to be used

Business realized by the futuristic technology Brain Navi^TM that accurately understands human sensations and cognition. In addition to the examples below, it is anticipated that Brain Navi^TM can be utilized in a wide range of fields such as product development, evaluation of user experience, emotional analysis, education, and healthcare.

Personalization of hearing aids

Adjustment of hearing aids takes time, and there are cases where users discontinue use due to poor adjustments. Use of ERPs enables objective and individualized adjustments based on brain responses. This is expected to shorten adjustment times and improve satisfaction, which also leads to an enhanced quality of life for users.

Use in game and training app development

Scenes where players respond strongly and the timings at which they withdraw from the game can be visualized with ERPs, enabling development of highly immersive and stimulating games. By combining this with observation of learning motivation, concentration, and emotions, the development of more effective games and training apps tailored to individual users can also be expected.

Marketing research

Latent awareness of brand logos and commercials can be measured. For example, content with a high latent awareness effect even in brief advertisements flowing on social media can be extracted, enabling effective advertising strategy and product design. This is a field that demonstrates the advantages of ERPs, which can measure momentary brain responses that are a challenge for the general brainwave (EEG) measurements already widely used in marketing.

Inspired by advances in fMRI technology, we began research and development of Brain Navi^TM from 2018 and have made continuous improvements since then. Brainwave analysis thus far has required multiple measurements, and our development team is working to balance both accuracy and practicality toward a future where meaningful measurement data can be obtained in a single observation.
We have achieved a lightweight and high-precision system that allows anyone to easily measure and analyze ERPs without the need for special equipment, environments, or staff. Brain Navi^TM holds great potential as a new standard that enables easy visualization of brain responses. If you are interested and see potential in utilizing ERPs, please feel free to contact us. We eagerly await partners who will help us carve out a path to a new future.
