Aim: Resting-state gamma oscillations, less studied compared to task-related gamma activity, have increasingly been considered to reflect baseline cognitive processes and readiness for future cognitive demands. Previous research has largely focused on clinical populations, identifying aberrant gamma activity as a marker of cognitive dysfunction in conditions such as schizophrenia, Alzheimer’s disease, and ADHD. This study investigates the relationship between resting-state EEG gamma power and neuropsychological performance in healthy adults. Specifically, it examines the associations between absolute and relative gamma power across different brain regions (frontal, temporal, parietal, and occipital) during resting-state and performance in cognitive domains such as working memory, verbal fluency, face recognition, shortterm memory, and attention. Material and Methods: A total of 45 healthy individuals who underwent routine neuropsychiatric evaluations at NP Istanbul Brain Hospital and exhibited no pathological findings were included in the study. Resting-state EEG data, collected retrospectively, were analyzed to extract gamma power values, which were subsequently correlated with neuropsychological test scores. Results: The results revealed significant positive correlations between relative gamma power in the frontal and parietal regions and verbal fluency performance. This association suggests that specific brain regions contribute uniquely to cognitive functions during resting states, with gamma power providing insight into the neural substrates of language-related abilities. Conclusion: These findings highlight the relevance of resting-state gamma power in understanding individual differences in cognitive abilities. Future research should validate these findings with larger, more diverse samples and incorporate advanced techniques like MEG to better understand the neural mechanisms linking gamma oscillations to cognitive performance

Dinlenme halindeki gamma osilasyonları, görevle ilgili gamma aktivitelerine kıyasla daha az incelenmiştir ve giderek artan bir şekilde temel bilişsel süreçleri ve gelecekteki bilişsel taleplere hazırlığı yansıttığı düşünülmektedir. Önceki araştırmalar büyük ölçüde klinik popülasyonlara odaklanmış ve gamma aktivitesindeki anormallikleri şizofreni, Alzheimer hastalığı ve Dikkat Eksikliği Hiperaktivite Bozukluğu (DEHB) gibi durumlarda bilişsel disfonksiyonun bir göstergesi olarak tanımlamıştır. Bu çalışma, sağlıklı yetişkinlerde dinlenme halindeki EEG gamma gücü ile nöropsikolojik performans arasındaki ilişkiyi araştırmaktadır. Özellikle, dinlenme sırasında farklı beyin bölgelerindeki (frontal, temporal, parietal ve oksipital) mutlak ve göreli gamma gücü ile çalışma belleği, sözel akıcılık, yüz tanıma, kısa süreli bellek ve dikkat gibi bilişsel alanlardaki performans arasındaki ilişkiler incelenmiştir. Çalışmaya, NP İstanbul Beyin Hastanesi'nde rutin nöropsikiyatrik değerlendirmelere tabi tutulmuş ve patolojik bulgu göstermeyen toplam 45 sağlıklı birey dahil edilmiştir. Retrospektif olarak toplanan dinlenme halindeki EEG verileri analiz edilerek gamma gücü değerleri çıkarılmış ve bu değerler nöropsikolojik test skorları ile ilişkilendirilmiştir. Sonuçlar, frontal ve parietal bölgelerdeki göreli gamma gücü ile sözel akıcılık performansı arasında anlamlı pozitif korelasyonlar ortaya koymuştur. Bu ilişki, dinlenme sırasında belirli beyin bölgelerinin bilişsel işlevlere özgün katkılarda bulunduğunu ve gamma gücünün dil ile ilişkili yeteneklerin nöral alt yapısına dair önemli bilgiler sağladığını göstermektedir. Bu bulgular, dinlenme halindeki gamma gücünün bireyler arası bilişsel farklılıkları anlamada önemini vurgulamaktadır. Gelecekteki araştırmalar, bu bulguları daha büyük ve daha çeşitli örneklerle doğrulamalı ve gamma osilasyonlarını bilişsel performansla ilişkilendiren nöral mekanizmaları daha iyi anlamak için MEG gibi ileri teknikleri içermelidir.
