Figure 2

Averaged power (ERSP) of the theta TFW (3–5 Hz, 100–400 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 steady response between the first and the second presentation of the /a/. Error bars represent standard error. *p < 0.01.
