Quantitative electroencephalography (qEEG) presents several limitations in assessing brain function when compared to traditional electroencephalography (EEG) methods. While qEEG offers advanced statistical analysis and the ability to quantify brain wave patterns through spectral analysis, it often relies on normative databases that may not account for individual variability, potentially leading to misinterpretation of results. Additionally, qEEG's reliance on complex algorithms and mathematical modeling can obscure the nuanced temporal dynamics of brain activity that traditional EEG captures in real-time. Furthermore, the spatial resolution of qEEG is inherently limited by the electrode placement and density, which may not adequately reflect localized brain activity or pathological conditions. The interpretative framework of qEEG can also be influenced by artifacts and noise, complicating the differentiation between physiological and pathological signals. Consequently, while qEEG provides valuable insights into brain function, its limitations in individual variability, temporal resolution, and interpretative complexity necessitate careful consideration when used alongside traditional EEG methodologies.

Integrating quantitative electroencephalography (qEEG) data with other neuroimaging techniques, such as functional magnetic resonance imaging (fMRI) and positron emission tomography (PET), can provide a multifaceted understanding of brain activity by combining the temporal resolution of qEEG with the spatial resolution of fMRI and PET. This multimodal approach allows researchers to correlate the dynamic electrical activity captured by qEEG, which reflects neural oscillations and event-related potentials, with the hemodynamic responses measured by fMRI and the metabolic activity indicated by PET. By employing advanced data fusion techniques, such as machine learning algorithms and multivariate pattern analysis, researchers can elucidate the complex interactions between different brain regions, identify biomarkers for neurological disorders, and enhance the understanding of cognitive processes. Furthermore, integrating these modalities can facilitate the exploration of brain connectivity, both at the local level through coherence and phase synchronization in qEEG, and at the global level through network analysis in fMRI, ultimately leading to a more comprehensive model of brain function and dysfunction.
