Creativity is a fundamental aspect of human cognition, particularly during childhood. Exploring creativity through electroencephalography (EEG) provides valuable insights into the brain mechanisms underlying this vital cognitive process. This study analyzed power spectrum and functional connectivity interhemispheric intrahemispheric activity creative tasks in 15 Argentine children aged 9 to 12, using 14-channel EEG system. The Torrance test thinking (TTCT) was used, incorporating one figural verbal task. metrics included relative spectral density (rPSD) across Delta, Theta, Alpha, Beta, Gamma bands. Spearman's Rho correlations were calculated between frequency bands performance on tasks, followed by assessment coherence analysis [1–50] Hz spectrum. results revealed significant increases rPSD all compared rest, with no differences tasks. Correlational positive associations Beta band innovative adaptive factors In contrast, for task, both positively related flexibility, while Alpha showed negative relationship fluency originality. Coherence enhanced synchronization, frontotemporal temporo-occipital regions, alongside reduced frontal coherence. These findings suggest that involves dynamic reorganization activity, characterized oscillatory activation region-specific changes. Our contributes deeper understanding supporting child development.

Hearing spoken words can enhance the recognition of visual object categories. Yet, mechanisms that underpin this facilitation are incompletely understood. Recent proposals suggest alter processes by activating category-specific representations in sensory regions. Here, we tested hypothesis neural oscillations serve as a mechanism to activate language-generated representations. Participants performed cue-picture matching task where cues were either words, their native or second language, natural sounds, while EEG and reaction times recorded. Behaviorally, found images cued recognized faster than those sounds. This indicates language activates more accurate semantic compared A time-frequency analysis cue-target intervals revealed label-advantage effect was associated with enhanced power posterior alpha (9–11 Hz) beta (17–19 Hz), both which larger when image preceded word sound. These results rhythms may play distinct functional roles support language-mediated recognition: might function amplify regions, (re)activate network states elicited auditory cue.
