qEEG Brain Mapping | Neurofeedback Athens
BrainMaster Discovery 24 — Unique in Greece
- Recording of the electrical activity in each part of the brain.
Is:
qEEG Brain Mapping is based on a multichannel EEG recording & its quantitative analysis.
Through electrodes applied to predetermined positions on the surface of the scalp, electrical potential differences related to brain activity are recorded.
EEG recording collects the initial electrical signal. Then, qEEG quantitative analysis calculates selected parameters of it & captures them in numerical data, diagrams & topographic maps.
qEEG is not a photographic or anatomical image of the brain. It captures quantitative characteristics of the electrical activity recorded at a specific time & under specific conditions.
How does it work:
- Surface sensors are used to detect electrical patterns of the brain (known as brain waves).
- Records brain activity & mode.
- Recognizes & records amplitude, phase, coherence & the brain wave symmetry.
- Identifies the areas of the brain which present either less or more activity than normal.
- Shows the areas of the brain whose activity between them is unconnected.
- It is non-invasive & without pain.
It is used for:
- Initial assessment
- Planning sessions & protocols
- Continuous session progress monitoring
TECHNOLOGY
Quantitative analysis may include:
-
The amplitude & absolute & relative power per frequency band
-
The distribution of individual frequencies & the peak alpha frequency
-
The symmetry or asymmetry between different recording positions
-
Coherence, phase relationships & time coordination between signals
-
Functional connectivity indicators between recording sites
-
The estimation of cortical source distribution via sLORETA
Simply put, the analysis looks not only at how much activity is recorded in each frequency band, but also at how it is distributed and how signals from different recording locations relate to each other.
Functional connectivity indices describe quantitative relationships & levels of coordination between recorded signals. They do not record direct "brainwave communication" & do not by themselves demonstrate anatomical connection or disconnection of brain regions.
How are the results obtained?
Data are processed through multiple quantitative analysis systems & compared, where applicable, with reference databases.
The same recording is examined through different montages & modes of representation, such as:
-
Linked Ears
-
Laplacian
-
Longitudinal
-
Transversal
-
sLORETA
The different montages are not separate recordings. They provide complementary ways of processing & examining the same original data.
For processing, the following are used:
-
qEEG-Pro & NeuroGuide, for quantitative analysis & comparison with reference databases
-
SARA — Standardized Artifact Rejection Algorithm, for artifact detection & rejection
-
sLORETA — Standardized Low Resolution Electromagnetic Tomography, for low-resolution estimation of cortical source distribution
The result is not limited to a single “map.” It can include topographic maps, numerical tables, detailed profiles, different representations of the record & comparative reports.
How is the data used?
At Athens Neurotraining Center, qEEG Brain Mapping precedes the start of EEG Neurofeedback & forms the basis for personalized training planning.
The results are not interpreted in isolation or in an automated manner. They are considered in conjunction with:
-
The individual history
-
The functional image
-
The demands of everyday life
-
The individual's individual goals
-
Any coexisting difficulties
-
The broader framework of support or care
The data can be used for:
-
The initial recording of selected parameters of electrical activity
-
The personalized design of EEG Neurofeedback protocols
-
The choice of recording locations & training parameters
-
Re-evaluating the design during the sessions
-
Comparison of the initial & repeat recording, when a second qEEG is performed
qEEG does not by itself predetermine the number of sessions, the course of training, or the outcome. The design is adapted to the data & the response of each individual.
Repeat qEEG & Comparison Report
When a second recording is performed after a substantial cycle of sessions, the newer data can be compared to the original recording via a Comparison Report.
The comparison is carried out, as far as possible, under corresponding conditions & examines the changes recorded in the same quantitative parameters.
The Comparison Report provides data for re-evaluating the EEG Neurofeedback design. It does not constitute evidence of clinical improvement in itself & is considered in conjunction with the functional picture and course of the individual.
Τι δεν είναι το qEEG Brain Mapping
Το qEEG Brain Mapping δεν προσδιορίζει την αιτία ενός συνόλου συμπτωμάτων & δεν λειτουργεί ως αυτοτελές διαγνωστικό μέσο.
Δεν αποτελεί απεικονιστική εξέταση όπως η μαγνητική ή η αξονική τομογραφία & δεν απεικονίζει ανατομικές βλάβες.
Δεν «διαβάζει» σκέψεις & δεν μετρά την ευφυΐα, την προσωπικότητα, το ταλέντο, το κίνητρο ή τις ικανότητες ενός ατόμου.
Δεν υποκαθιστά το κλινικό EEG ή τη νευρολογική, ψυχιατρική, ψυχολογική ή άλλη ιατρική αξιολόγηση, όταν αυτές ενδείκνυνται.
Στο Athens Neurotraining Center, τα δεδομένα του αξιοποιούνται για τον εξατομικευμένο σχεδιασμό της Νευροανάδρασης EEG & μπορούν να ενταχθούν συμπληρωματικά σε ένα ευρύτερο πλαίσιο υποστήριξης, σε συνεργασία με τους θεράποντες επαγγελματίες του εκάστοτε ατόμου.
