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.
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 has developed two primary technology platforms for non-invasive brain monitoring:
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

- Research Applications: Targeting understanding of complex neurological conditions
- Early Detection: Focusing on biomarker discovery for early disease identification
Kernel's technologies are being applied to several critical neurodegenerative disease research areas:
Kernel Flow enables detailed monitoring of cerebral hemodynamics associated with cognitive decline:
- Prefrontal Cortex Analysis: Changes in prefrontal blood flow patterns during cognitive tasks
- Temporal Lobe Monitoring: Hemodynamic responses in memory-related regions
- Resting State Connectivity: Functional connectivity alterations in default mode network
- Biomarker Potential: Exploring early hemodynamic changes as disease progression markers
- Treatment Monitoring: Objective measures for therapeutic intervention efficacy
For Parkinson's disease research, Kernel technologies enable:
- Motor Cortex Activation: Monitoring cortical activity during movement tasks
- Basal Ganglia-Cortical Circuitry: Understanding dysfunctional motor networks
- Treatment Response: Tracking hemodynamic changes in response to dopaminergic therapies
- Gait Analysis: Cortical involvement in gait and balance disturbances
- Freezing of Gait: Neural correlates of episodic movement blocks
Kernel's devices are being evaluated for detecting early signs of cognitive decline:
- Preclinical Detection: Identifying at-risk individuals before full dementia develops
- Longitudinal Monitoring: Tracking disease progression with objective measures
- Intervention Timing: Enabling earlier therapeutic intervention
- Risk Stratification: Helping identify patients who may benefit from preventive strategies
Kernel technologies also support research into:
- Stroke: Recovery monitoring and rehabilitation guidance
- Traumatic Brain Injury: Assessing cognitive function and recovery
- Depression: Prefrontal cortex involvement in mood disorders
- Epilepsy: Seizure prediction and monitoring
Kernel equipment is deployed in leading research institutions:
