Time–frequency and functional connectivity analysis in drug‐naive adolescents with depression based on electroencephalography using a visual cognitive task: A comparative study

During cognitive tasks, adolescents with depression display distinct abnormalities in both high- and low-frequency brain oscillations, as well as reduced functional connectivity in the frontal, central, and parietal regions compared to HC. These findings offer valuable neuroelectrophysiological insights into the cognitive deficits associated with adolescent depression.
