Abstract
Measuring the impact of a task on resting state networks (RSNs) is important for understanding their relative strength and stability. Little is known about RSN stability in adults and less is known about RSN stability in children. The effect of an active task on RSNs was measured on fourteen children using functional magnetic resonance imaging (fMRI). The auditory, sensorimotor, and default mode RSNs and the speech network were measured before, during, and immediately following overt speaking. The results indicated that before overt speaking, these RSNs were stronger with greater areas of activation compared to immediately following the task. The speech network showed a shift from right- to left- activation, from rest to speech, respectively. These results demonstrate the importance of studying task effects on RSNs and contribute to understanding neural development in healthy children. This research provides a basis for clinical applications in terms of identifying treatment effects on RSNs.
