Averaged power (ERSP) of the beta TFW (10–30 Hz, 0–200 ms) for each group, at the first visit, in the central region. Normocephalic infants (orange line) showed a U-shaped pattern in response to the entire standard trial (/a1/-/a2/-/a3/-/I/) while macrocephalic infants (yellow line) showed a relatively steady response between the first and the second presentation of the /a/. Error bars represent standard error. **p < 0.001.
