Données de réplication pour "Auditory evoked Delta-brushes involve stimulus-specific cortical networks in preterm infants"

This dataset contain EEG files recorded in newborns aged 30-38 post menstrual weeks), using 32 electrode neonatal caps according to 10/10 international system. Babies received auditory stimuli presented with constant sound volume via headphones (click at 70 dB sound pressure level and a recorded male voice pronouncing the word “bébé” around 50 dB SPL. Auditory evoked responses (AERs) including their late component, evoked delta-brushes (DBs) were analyzed after averaging of AERs, frequency power spectrum analyses and time-frequency analyses. The dataset contain Excel files with frequency power spectrum (PS) values of mean-referenced signals computed over 2-sec time intervals using the Fast Fourier Transform (FFT) algorithm immediately preceding and following auditory stimuli in 6 frequency bands: delta; theta; alpha; beta; gamma and high-gamma. These PS values were analyzed in population statistical analysis . Overall, our study showed stimulus-specific scalp topography of evoked DBs as well as of evoked oscillations more widespread for the “click”-response. These results suggests that auditory-evoked oscillations underlie specific auditory processing during fetal development.
