OculomotorEye movement
Brainstem · cerebellum · frontal cortex
Smooth-pursuit gain (horizontal and vertical), saccade latency and velocity, vestibulo-ocular reflex gain, convergence, and fixation stability, all from the front camera.
Technology · the platform
One session. Four brain systems. One coherent score.
An objective, phone-based assessment. A short guided capture reads four functional brain systems, fuses them into a single calibrated index, and scores it against your own baseline. Built for concussion and TBI first.

The science · what we read
Four systems, real neural machinery.
Each test maps to specific brain circuitry. The eyes and balance run on involuntary systems a person cannot consciously modulate, which is what makes the reading resist gaming.

PosturalBalance
Vestibular · cerebellar systems
Three-stance Romberg, sway path, and center-of-mass drift from 33-point kinematics.

CognitiveProcessing and control
Prefrontal · cortical networks
Trail-making and Stroop interference under escalating cognitive load.
04Voluntary
ReactionMotor timing
Sensorimotor networks
Simple reaction time with randomized inter-stimulus intervals, captured to the millisecond.
An anti-saccade prefrontal-inhibition probe is in integration, and additional involuntary channels are in active development. We label status honestly and only score what is validated.
d-CIIV · the scoring engine
Coherence, not performance.
A healthy brain keeps its systems tightly coupled: oculomotor, postural, cognitive, and motor-timing move together. Injury pulls them apart. Concussion, TBI, and the chronic course of CTE show up as dispersion, signals drifting from one another and from the person's own baseline.
Our Dispersion-Based Cognitive Intra-Individual Variability framework turns that dispersion into one continuous, calibrated, longitudinally-comparable index. The score sits low when the systems stay coherent and rises as they drift, so lower is better, and recovery reads as a return toward baseline.
Manipulation-resistant by construction
The platform pairs voluntary task performance (the cognitive screens, held stances, and reaction test) with involuntary biomarker channels (saccadic latency and velocity, smooth-pursuit and vestibulo-ocular reflex gain, gaze stability, postural micro-corrections). A person trying to under-perform a baseline degrades the voluntary channels while the involuntary ones stay physiologically anchored, and that divergence is itself a flagged signal. It is the architectural answer to the sandbagging and concealment that defeat self-report screens.
The edge · multi-baseline
Scored against you, not a population.
Because a capture takes only minutes, we take a series over time and build each person's own longitudinal baseline, a distribution rather than a single noisy point. Every reading is scored against that personal band, and drift out of it flags real change earlier than a symptom would.
Learns your normal
Repeated captures reveal a person's true baseline and their day-to-day variability.
Catches subtle change
Small drift after a hit or a hard stretch stands out against the person's own history.
Return-to-play and duty
Decisions rest on the trend back to baseline across sessions, not one symptom-free day.
The index
One number, read against yourself.
The launched indication is concussion, TBI, and CTE. The headline output is the Cognitive Likelihood Index, a continuous score calibrated to each person's own baseline.
Cognitive Likelihood IndexLower is better
0–100
A continuous dispersion score. It sits low when your systems stay coherent and rises as they drift apart, tracked over time against your own baseline.
A family of calibrated indices extends from the same capture, a per-person sensitivity profile, a return-to-play and duty threshold, and severity and longitudinal-risk indices, on the roadmap as validation matures.
Intellectual property
Seventeen filings. One portfolio.
Not seventeen unrelated ideas. One method, anchored on concussion and TBI and protected in layers: the scoring foundation, the signals that feed it, and the broader platform it extends into.
