Driving a paradigm shift with high-precision noninvasive brain–computer interfaces.
Magnetically Biased Probes (MBP) is a brain-signal measurement technology that enables noninvasive recording with high temporal and spatial precision. We aim to build a system in which AI interprets high-resolution brain information acquired in real time.
We envision the following applications:
• Brain-controlled robots that combine motor imagery—including unconscious information—with physical AI.
• Systems that use AI to decode language information in the brain’s neural networks and output it simultaneously as speech and text.
• Visualization of dynamic visual imagery.
MAGNETICALLY BIASED PROBES
01 / NONINVASIVE
Noninvasive measurement
Convenient, safe and precise brain-signal measurement without inserting electrodes into the skull.
02 / WHOLE-HEAD
Reading signals across the whole head
Magnetic sensor–coil modules positioned across the head capture the dynamics of brain activity.
03 / SPATIOTEMPORAL
Precision in time and space
Measuring brain information with both high temporal and high spatial resolution.
01 — OUR TECHNOLOGY
Picking up neural electrical activity
with a bias magnetic field.
Magnetically Biased Probes / MBP
MBP is our proprietary brain-signal measurement technology, using a weak static magnetic field generated by a coil placed on the scalp. The field applied from the coil to the brain picks up magnetic-field fluctuations associated with neural electrical activity with high spatial precision, and a magnetic sensor detects them.
01
Apply a bias magnetic field to the brain
A coil placed on the scalp applies a weak static magnetic field toward the cerebral cortex.
02
Pick up neural electrical activity
The bias magnetic field picks up magnetic-field fluctuations associated with neural electrical activity in the brain.
03
Read dynamic brain activity at high resolution
Magnetic sensors measure the brain signals picked up by the bias magnetic field. Signals recorded at multiple locations reveal the dynamics of brain activity at high resolution.

Concept of MBP Measurement
02 — PROTOTYPE
Visualizing the whole brain
as a single network system.

Prototype of a 159-channel whole-head MBP system
From a research prototype
to technology for everyday use.
Gush is developing a 159-channel whole-head MBP system prototype. By placing multiple measurement modules across the head, we are working toward a system that captures the dynamics of brain activity.
We are pursuing measurement precision, signal quality and ease of fitting to bring high-precision, noninvasive brain–computer interfaces into practical use.
