EEG Core Laboratory
Centralised EEG Quality Control and Advanced qEEG Analysis at Scale
A central EEG core laboratory gives a research programme one consistent place to check, process and analyse electroencephalography data from every participant, visit, device and site. Instead of each site interpreting recordings differently, a central EEG core-laboratory model applies the same technical quality control, the same analytical configuration and the same reporting structure across the whole study.
Neuromap™ operates as a central EEG core laboratory for clinical trials, translational research and scientific publication. The service is built around the study protocol and the intended research questions, so that quantitative EEG (qEEG) outputs are comparable, traceable and ready for downstream statistical work.
What a Central EEG Core Laboratory Does
In multi-site and longitudinal studies, variability in acquisition, montage, sampling rate, metadata and preprocessing can quietly undermine comparability. A central EEG core laboratory removes much of that variability by standardising how data are received, checked and analysed.
- Central intake of pseudonymised or de-identified EEG recordings, as appropriate, through an approved secure transfer route.
- Consistent technical quality control for completeness, channel integrity, artefact burden and protocol conformity.
- A predefined, protocol-specific set of qEEG variables generated with fixed processing settings.
- Longitudinal and cohort comparison using controlled, documented configurations.
- Structured exports and study-level reporting suitable for the analysis plan or manuscript.
Why Centralisation Improves EEG Research Quality
When EEG is processed locally at each site, differences in reference, filtering, artefact handling and software configuration can make pooled analysis difficult. Centralised processing applies one prospectively defined pipeline to eligible recordings, reducing avoidable methodological variability. Residual device, site and acquisition effects are documented and, where necessary, addressed in the analysis plan.
Core-Laboratory Workflow
- Feasibility and protocol review — acquisition, format, montage, sampling and objectives are checked before intake.
- Secure data intake — pseudonymised or de-identified files, as appropriate, and required metadata are transferred through the approved route.
- Technical quality control — recordings are screened against defined acceptance criteria.
- Advanced qEEG analysis — eligible data pass through the configured Neuromap™ pipeline.
- Reference and longitudinal comparison — outputs are contextualised where methodologically appropriate.
- Specialist review — findings and exceptions are reviewed before release.
- Research deliverables — structured variables, figures and study-level summaries are delivered.
Compatibility Across Acquisition Systems
A central EEG core laboratory should not force every site onto one recording system. Neuromap™ can assess technically suitable recordings produced by different EEG systems, provided format, montage, sampling and quality meet the agreed study specification. Feasibility review confirms which configurations are compatible before production begins.
Positioning and scope
Neuromap™ provides EEG and qEEG data analytics for research. Outputs are data and neutral observations only; a suitably qualified clinician or investigator completes all interpretation. Neuromap™ does not provide a clinical diagnosis and is not an accredited clinical diagnostic laboratory.
The core-laboratory model described here is an analytical and scientific-support service. It complements, and does not replace, clinical EEG interpretation, neurological assessment, biostatistics or regulatory strategy.
When to Use a Central EEG Core Laboratory
Not every study needs a central EEG core laboratory, but several situations make one close to essential. Multi-site trials, longitudinal programmes with several visits, high-volume datasets and studies intended for publication all benefit from the consistency a central EEG lab provides. If a programme collects EEG from more than one site or more than one timepoint, the case for centralised EEG analysis becomes strong.
The alternative — letting each site analyse its own recordings — tends to introduce differences that are difficult to unpick later. A central core-laboratory model front-loads the standardisation so that the dataset is analysable as a whole, rather than as a collection of incompatible parts.
What sponsors and reviewers expect from an EEG core lab
Sponsors, ethics committees and journal reviewers may require transparent and reproducible EEG analysis. The core-laboratory workflow records how each recording was checked, which variables were computed, which settings and software versions were used, which recordings were excluded and why, and which exceptions required review. This documentation is generated prospectively within the study configuration and retained as a study-specific audit trail under the agreed quality and version-control procedures.
- Documented acquisition specification issued before data collection.
- Version-controlled analytical configuration.
- Transparent exclusion and exception log.
- Structured, machine-readable exports for statistics.
- Study-level quality and analysis reporting at milestones.
Central EEG Core Laboratory and Data Governance
Because a central EEG core laboratory receives data from multiple sources, data governance matters. Recordings are pseudonymised or de-identified as appropriate before transfer, moved through an approved secure route and processed under written data-protection terms. Neuromap™’s role under data-protection law and the applicable hosting and data-residency arrangements are documented for each engagement. The public website does not invite transfer of identifiable participant data through an ordinary web form.
Who Uses a Central EEG Core Laboratory
A central EEG facility is used by organisations that share one need: consistent, comparable EEG analysis across a study. Contract research organisations use a central EEG facility to add specialist capability to sponsor programmes. Pharmaceutical and biotechnology companies use it to support early-phase and translational research. Universities, hospitals and research consortia use a central EEG lab to access advanced analytics and publication-oriented outputs without building every computational module in-house.
- Contract research organisations adding EEG capability to bids and studies.
- Pharmaceutical and biotechnology sponsors running early-phase or CNS programmes.
- Phase I and healthy-volunteer units processing repeated recordings.
- Universities, hospitals and consortia running investigator-led research.
- Medical device and neurotechnology teams evaluating EEG-derived effects.
In each case, the central EEG core-laboratory model provides one coordinated pathway from feasibility and quality control through analysis, specialist review and final research deliverables.
How a Central EEG Core Laboratory Engagement Begins
A core-laboratory engagement usually begins with a feasibility review. The study team shares the outline, expected EEG volume, acquisition specification and required deliverables. Neuromap™ assesses technical compatibility, defines the proposed analysis pathway and provides a study-specific quotation. For larger or high-volume programmes, secure review of representative pseudonymised or de-identified sample recordings can establish compatibility before the full central EEG facility workflow is contracted.
What you receive
Engagements deliver a coordinated set of outputs rather than a single file, so that the study team has everything needed for downstream analysis and reporting.
- Structured, machine-readable data exports keyed by participant and visit.
- Clear tables and publication-oriented figures where requested.
- A documented record of settings, definitions and any exclusions.
- Study-level summaries at agreed milestones.
- Optional specialist scientific review at the contracted service level.
Every deliverable is prepared in professional British English and is designed to slot directly into the study team’s statistical, regulatory or manuscript workflow.
Getting started
Setting up a centralised service is straightforward and low-risk. The usual first step is a short feasibility review. The study team shares the research outline, the expected data volume, the acquisition details and the deliverables required. Compatibility is then confirmed and a study-specific scope and quotation provided before any commitment.

Frequently asked questions
Common questions about central EEG core-laboratory services.
What is an EEG core laboratory?
It is a central facility that applies consistent quality control and analysis to EEG data collected across participants, visits, devices or sites to improve comparability and support reproducibility across a study.
Does a central EEG lab replace site EEG readings?
No. Neuromap™ provides standardised research analytics and data outputs. Clinical EEG reading and any medical interpretation remain with appropriately qualified clinicians.
Can different EEG machines be used across sites?
Potentially. Each system, montage and configuration is assessed during feasibility review to confirm technical compatibility with the study specification.
Is the core laboratory accredited?
Neuromap™ provides EEG data analytics and is not an accredited clinical diagnostic laboratory. Any accreditation requirement should be defined explicitly in the study agreement.
Can you receive data from our existing sites?
Yes. Sites continue recording to an agreed specification; pseudonymised or de-identified data, as appropriate, are transferred through an approved secure route for central processing.
Do you support both resting-state and task recordings?
Both can be supported where the acquisition specification and data quality allow; suitability is confirmed at feasibility.
Limitations and important notes
- Comparability depends on acquisition quality, standardisation and accurate metadata.
- Reference comparison does not by itself establish diagnosis or clinical significance.
- Any published figure for analytical-output count, reference datasets, processing capacity or turnaround is conditional on the documented platform version and the requirements of the specific study.
