Get Your Brain Scanned at Alleviant

Spectral EEG (sEEG) is a quick, painless, non‑invasive brain scan that measures electrical activity across all 19 major regions of your brain. It helps map how your brain functions and identifies areas of under‑ or over‑activity related to emotional, cognitive, or behavioral symptoms.

The scan takes only about 4 minutes from start to finish, without gel, glue, or discomfort.

No. sEEG is designed to be completely painless and stress‑free. There is no gel, no glue, and no invasive equipment. Most people find it easier than they expect.

No. You do not need a formal diagnosis to request an sEEG. It’s available whether you’re starting a treatment journey, seeking clarity on symptoms, or simply wanting a baseline for brain performance.

An sEEG scan can highlight patterns of brain activity associated with depression, anxiety, ADHD, trauma, OCD, sleep issues, memory and attention challenges, or the impact of stress and nutritional factors on your brain.

What Each Lead Measures:

• Fp1 (Left Prefrontal Cortex): Situational awareness; vigilance

  Helps monitor the environment and stay alert. Important for attention and risk assessment.

• Fp2 (Right Prefrontal Cortex): Impulsivity; decision control; perseveration

  Regulates impulsive behavior, repetitive thoughts/actions (perseveration), and decision-making control.

• FZ (Midline Frontal Cortex): Execution functions; linear tasks

  Coordinates goal-oriented behavior, focus, and structured task execution.

• F3 (Left Frontal Cortex): Expressive language; verbal impulse control

  Supports language production and controlling outbursts or verbal impulsivity.

• F4 (Right Frontal Cortex): Judgement and planning

  Involved in higher-order thinking, planning future actions, and evaluating consequences.

• F7 (Anterior Temporal-Frontal Junction): Language, reading comprehension

  Integrates verbal processing and understanding, especially reading comprehension and syntax.

• F8 (Right Lateral Frontal): Emotional availability

  Connects emotional regulation with social responsiveness and empathy.

• CZ (Central Midline): Primary somatosensory; gross motor function

  Involved in basic body sensation (like touch) and control of large body movements (walking, posture).

• C3 (Left Central): Right-sided somatosensory; fine motor skills

  Controls right-hand fine movements and senses; handwriting, buttoning, etc.

• C4 (Right Central): Left-sided somatosensory; fine motor skills

  Controls left-hand fine movements and body sensations.

• T3 (Left Temporal): Auditory processing; sound perception

  Processes sound, speech recognition, and phonetic interpretation.

• T4 (Right Temporal): Auditory processing; sound perception

  Non-verbal sound perception (e.g., music, tone), emotional intonation in voices.

• PZ (Midline Parietal): Visual memory; cognitive function; dreaming

  Integrates visual memories and imagination; also linked with REM/dreaming.

• P3 (Left Parietal): Visuospatial memory; depth perception

  Helps understand spatial orientation and 3D positioning (important for driving, sports, etc.).

• P4 (Right Parietal): Visuospatial memory; analytical skills

  Adds logic, calculations, and analytical problem-solving to spatial memory.

• P7 (Left Parieto-Occipital): Secondary visual processing; night vision

  Supports processing of visual scenes and low-light visuals.

• P8 (Right Parieto-Occipital): Secondary visual processing; color; shapes

  Helps recognize complex visuals like color, form, and abstract patterns.

• O1 (Left Occipital): Primary visual processing; visual acuity

  Handles initial visual input such as sharpness, brightness, shapes, etc.

• O2 (Right Occipital): Primary visual processing; visual acuity; depth perception

  Adds depth, dimension, and more complex spatial understanding to visual signals.

• A2 (Right Ear/Mastoid Area): Heart rate

  Sometimes reflects autonomic nervous system signals; may correlate with HR variability or arousal.

The scan provides objective data that helps your provider tailor treatments like TMS or personalized PrTMS® protocols. It also allows your clinician to track progress over time and adjust care based on how your brain responds.

sEEG can benefit anyone experiencing emotional or cognitive symptoms, anyone who hasn’t found progress with prior treatments, those starting or adjusting medications, or individuals seeking to optimize brain performance.

You can schedule an sEEG by contacting Alleviant through the form on this page, on the Scheduling page, or by calling (866) 951-4325. Your care team will help you choose the best time and prepare you for your visit.

At Alleviant, we believe in transparency and clarity when it comes to your care and billing. Please review the following options for scheduling and payment of spectral EEG (sEEG) services:

1. If you are a new patient seeking full-service mental health care:

   You may schedule a comprehensive intake appointment, during which we will discuss whether an sEEG is appropriate for your needs. If included as part of your overall evaluation and care plan, the sEEG may be included as part of your treatment plan.

2. If you’re an established patient:

   The cost of your sEEG may already be included in your ongoing appointment charges, depending on your treatment plan. We recommend discussing this with your provider to confirm how it applies in your case.

3. If you only want an sEEG:

   We offer a self-pay option for stand-alone sEEG appointments. The cash rate is $250. We do not bill insurance for stand-alone sEEG scans.
