Özet:

 COVID-19 has effects on the neurological and microvascular systems. Based on this information, in this study, event-related potentials were compared from EEG signals recorded by the same people and the same experimental procedure before and after COVID-19. The spectrogram images obtained using different wavelet transform types were compared using the Cz, P3, P4, Pz, P7, P8, O1, Oz, and O2 channels before and after COVID-19. When the results are examined, it is seen that there is a decrease in activation in the Oz, P8, P7, and P4 electrodes between the 4 Hz frequency region and the 100 to 300 ms time region. In order to reveal the difference more clearly, the power coefficient values obtained by using different wavelet types were compared. The most significant reduction rate after COVID-19 occurred in the bump wavelet type, with 16.10. For Morse and amor wavelet types, wavelet transform coefficient power reduction of 14.22 and 14.25, respectively, occurred. The most significant difference in terms of channels occurred in the Oz channel.

 COVID-19un nörolojik ve mikrovasküler sistem üzerinde etkileri bulunmaktadır. Bu bilgiden hareketle bu çalışmada COVID-19 öncesi ve COVID-19 sonrası aynı kişiler ve aynı deney prosedürüyle kaydedilmiş EEG sinyallerinden elde edilen olay ilişkili potansiyeller karşılaştırılmıştır. Farklı dalgacık dönüşümü türleri kullanılarak elde edilen spektrogram görüntüleri Cz, P3, P4, Pz, P7, P8, O1, Oz ve O2 kanalları kullanılarak COVID-19 öncesi ve COVID-19 sonrası durumları karşılaştırılmıştır. Sonuçlar incelendiğinde, 4 Hz frekans bölgesi ve 100 ile 300 ms zaman bölgesi arasında Oz, P8, P7 ve P4 elektrotlarında bir aktivasyon azalmasının meydana geldiği görülmektedir. Farklılığın daha net ortaya konulabilmesi için, farklı dalgacık türleri kullanılarak elde edilen güç katsayısı değerleri karşılaştırılmıştır. COVID-19 sonrası en büyük azalma oranı 16.10 ile bump dalgacık türünde meydana gelmiştir. Morse ve amor dalgacık türleri içinse sırasıyla 14.22 ve 14.25lik dalgacık dönüşümü katsayısı güç azalması meydana gelmiştir. Kanallar açısından en büyük farklılık Oz kanalında meydana gelmiştir.
