and adults and between species may limit interpretation of the data even though the electrode locations were corrected for size differences. In humans it has been suggested that differences in EEG amplitude between children and adults may be due to skull thickness [124]. However, this cannot be the case in the present study in the rats as all recordings were made with implanted electrodes, which eliminates the issue of skull thickness. Another limitation was that ERO comparisons between species were restricted to the use of a simple passive task and/or comparisons of non-attended tones. This may restrict the usefulness of these electrophysiological indices of development with respect to their relationship to cognitive development and/or task requirements. However, recent studies using measures of multivariate pattern classification analysis to examine maturation in task-induced brain activation and in functional connectivity during adolescence have found that functional brain maturation in adolescence is driven by a common process across cognitive tasks as opposed to being task specific [125]. The authors further proposed that brain connectivity changes over the course of adolescence affect brain functionality at a basic level that is common in the simplest go-no-go task and in a complex gambling task [125]. We have
