THE NSFL1 NEUROSCAN EXAM
How NSFL1 NeuroScan Works
A non-invasive, 45-minute session on an objective, FDA-cleared device, followed by machine learning analysis and a complete board-certified neurologist overread.
WHAT'S INCLUDED
The NSFL1 NeuroScan Diagnostic Package
One objective, FDA-cleared device delivers a diagnostic group of seven components:
EEG
A 21-channel recording of the brain's electrical activity, eyes open and eyes closed.
Quantitative EEG (qEEG)
That activity compared statistically against a normative database.
ERP
Millisecond-level measures of how quickly the brain responds to visual and auditory stimuli.
EKG
A cardiac recording with rhythm analysis and heart rate variability.
Brain Mapping
Z-scored head maps and 3D LORETA source maps showing where activity falls outside the normal range.
Machine Learning Analysis
Models trained on more than 200,000 qEEG, ERP and neuropsychological reports flag patterns associated with mTBI.
Completed board-certified neurologist overread
Clinical findings and brain maps in a written report.
Also captured during the same visit: reaction-time testing and a patient symptom self-assessment.
WHAT WE TEST FOR
mTBI, PTSD, ADHD and up to Ten Neural Biomarkers
Step-by-Step
Referral
A physician completes the NSFL1 NeuroScan Imaging Referral Form; our team contacts the patient to schedule.
Testing visit
A comfortable sensor cap records brain activity while the patient rests and completes simple on-screen tasks (about 30 minutes).
Analysis
Recordings are compared against normative data, mapped, and run through machine learning models trained on 200,000+ qEEG, ERP and neuropsychological reports.
Neurologist overread
A board-certified neurologist completes a full overread and issues a report with clinical findings and brain maps.
Report delivered
The report goes to the referring physician to support clinical decision-making.

WHAT THE EXAM MEASURES — KEY MARKERS
Brain Responses, Measured to the Millisecond
ERP testing records the brain's direct response to a sight, a sound or a task. Each result is compared against a normative reference and graded on an easy-to-read A-F color scale.
Marker | What it reflects
| Reference |
|---|---|---|
Visual reaction (N2) | How quickly the brain registers what it sees | < 220 ms |
Auditory sensation (P2) | How quickly the brain registers what it hears | < 120 ms |
Attention / vigilance (P300) | Focus and attention during a go/no-go task | < 340 ms |
Information processing / working memory (N400) | Speed of higher-level thinking | < 480 ms |
Reaction time & variance | Physical response speed and consistency | 350-500 ms; variance < 10 ms |
Missed & wrong responses | Errors of omission (missed) and commission (impulsive or incorrect) | ≤ 6% missed; ≤ 4% wrong |
EEG frequency markers | Peak alpha frequency, theta/beta ratio, frontal alpha asymmetry, alpha reactivity | Age-normed ranges |
WHAT'S IN THE REPORT
A Report Built for the Treating Physician
TIMING — WHEN TO TEST
The Ideal Testing Window
Window | What it means
|
|---|---|
Days 0–30 (acute) | The brain is still in metabolic recovery, and many concussions resolve on their own within 3–6 weeks. |
Days 31–90 (recommended) | If symptoms persist past 30 days, this window offers the best opportunity to capture objective functional markers. |
Day 91+ (chronic) | Testing can still document lasting changes and may help establish persistence of symptoms. Mood-related markers may also appear. |
Patients whose symptoms persist beyond 30 days should talk with their treating physician about scheduling a NSFL1 NeuroScan.
FREQUENTLY ASKED QUESTIONS
NSFL1 NeuroScan Exam Questions
Is it painful or invasive?
No. There are no needles, no radiation and no injections.
How long does it take?
Plan for about an hour at the office; the recording itself is about 30 minutes.
What does the patient do?
Rest quietly with eyes open and closed, then respond to simple pictures and sounds on a screen.
Does it diagnose a brain injury by itself?
No. Results are interpreted in the context of the patient's history and exam; the final diagnosis rests with the treating physician.
Does it replace CT or MRI?
No. It complements structural imaging with functional information.
Who reads the results?
Every study receives a complete overread by a board-certified neurologist.
