Overview
Kernel is a neurotechnology company developing non-invasive brain monitoring and recording devices. Founded in 2016 and based in Los Angeles, California, Kernel specializes in quantitative neuroimaging technologies designed for both research and clinical applications. The company's mission is to build devices that can measure and interpret brain activity with unprecedented precision, making brain data accessible for understanding neurological conditions and developing new therapeutics[@kernel].
Unlike many BCI companies focused on invasive approaches, Kernel exclusively develops non-invasive technologies, positioning itself as a leader in wearable, safe brain monitoring suitable for broader patient populations, including elderly individuals with neurodegenerative conditions who may not be candidates for surgical implants[@kernel].
Kernel has developed two primary technology platforms for non-invasive brain monitoring[@kernel][@mintzer2022]:
Kernel Flow
Kernel Flow represents a significant advancement in functional near-infrared spectroscopy (fNIRS) technology:
- Measurement Principle: Uses diffuse optical tomography to capture hemodynamic responses
- Spatial Resolution: High spatial resolution across cortical regions
- Wavelength: Multiple near-infrared wavelengths for depth discrimination
- Coverage: Multiple optodes for broad cortical coverage
- Portability: Designed for clinical and research settings
