Figure 1.
Normal developmental trajectory of cognitive executive function. The trajectory of cognitive executive functioning development is derived from developmental tables in the Wisconsin Card Sorting Manual [modified from Heaton et al. (1993)]. The other trajectories correspond to the spectral power in gamma bands during a face recognition task (30–75 Hz, all electrodes; Uhlhaas et al., 2009) as well as cumulative increments in computer quantified changes in EEG frequency spectrum (QEEG) between fronto-temporal cortices, derived from Hudspeth and Pribram (1990).
