Source activity plotted via Brainstorm (version 2022 February; https://neuroimage.usc.edu/brainstorm) (B) Grand-average ERP difference waveforms (300–200 ms) elicited by noise segments for 4- and nine-month-olds (marked by line colors) from a parietal (Pz, left) and a frontal lead (F4, right). The time windows of clusters are drawn with solid lines below the ERPs. Scalp activity plotted via EEGLAB software (std_plotcurve function; https://www.mathworks.com/matlabcentral/fileexchange/56415-eeglab ) (C) Topographical distribution across the scalp of the clusters differentiating the two age groups. The positive cluster indexes stronger activity at 4- compared to 9-months, while the negative cluster indexes stronger activity at 9- compared to 4-months. Topographical maps are plotted via Brainstorm toolbox.
(A) Significant current source density difference between the responses to long (300 ms) and short (200 ms) noise segments after permutation testing depicted over the inflated cortex.
