What Information Is Included in a SAM EEG Report?

Report Overview

The report includes information from both the eyes-open and eyes-closed recording conditions and presents EEG findings in a structured format.

Typical sections include:

• Data Quality Summary
• Midline Arousal Regulation Profile
• Vigilance Regulation
• Frontal Alpha Asymmetry (FAA)
• Theta Beta Ratio (TBR)
• Individual Alpha Peak Frequency (iAPF)
• Raw EEG Recordings
• Scalp Maps

Data Quality Summary

The report includes a data quality section that shows how much EEG data was retained after automated artifact rejection.

This section helps clinicians understand the quality of the recording and the amount of usable EEG data available for analysis.

Examples of artifacts that may be detected include:

• Muscle activity
• Eye blinks
• Movement-related activity

Midline Arousal Regulation Profile

This section displays EEG activity recorded from the midline channels:

• Fz
• Cz
• Pz

It presents power spectra across standard EEG frequency bands, including:

• Delta
• Theta
• Alpha
• Beta
• Gamma

The report also identifies the alpha peak within the spectrum.

Vigilance Regulation

The vigilance section examines changes in EEG activity across the recording period.

This section includes:

• Eyes-open and eyes-closed comparisons
• Temporal vigilance dynamics
• Condition summaries
• Overall interpretation summaries
• Clinical relevance information

Frontal Alpha Asymmetry (FAA)

The FAA section evaluates alpha activity differences between left and right frontal brain regions.

The report presents:

• Eyes-open measures
• Eyes-closed measures
• Condition comparisons
• Interpretation summaries
• Clinical relevance information

Theta Beta Ratio (TBR)

The report includes Theta Beta Ratio measurements derived from the EEG recording.

This section contains:

• Eyes-open results
• Eyes-closed results
• Condition comparisons
• Protocol-related information
• Interpretation summaries
• Clinical relevance information

Individual Alpha Peak Frequency (iAPF)

The iAPF section evaluates the dominant alpha frequency observed during the recording.

The report includes:

• Peak alpha frequency values
• Eyes-open and eyes-closed comparisons
• Alpha reactivity information
• Interpretation summaries
• Clinical relevance information

Raw EEG Recordings

The report contains representative segments of the recorded EEG data for:

• Eyes Open
• Eyes Closed

These sections provide access to the underlying EEG recording.

Scalp Maps

The report includes scalp maps that visualize how EEG activity is distributed across the scalp.

The report contains:

• Absolute power maps (Eyes Closed)
• Absolute power maps (Eyes Open)
• Relative power maps (Eyes Closed)
• Relative power maps (Eyes Open)

These visualizations provide a topographic view of EEG activity across recording locations.

Interpretation Support

Several sections of the report include additional interpretation support, such as:

• Condition summaries
• Overall interpretation summaries
• Clinical relevance descriptions
• Interpretation guidance
• Suggested review considerations

These sections are intended to help clinicians review EEG-based information within the broader clinical context.

Important Notes

• SAM EEG reports are generated from recorded EEG data.
• Reports include information from both the eyes-open and eyes-closed recording conditions.
• The report provides structured EEG-based information and EEG-derived measures for clinician review.
• EEG findings should be reviewed alongside patient history, clinical observations, and other relevant clinical information.
• SAM EEG reports do not provide diagnoses, treatment recommendations, or automated treatment instructions.
• Clinical interpretation and decision-making remain the responsibility of the healthcare professional.
