Abstract Objective To determine the association of default mode (DMN) and salience (SAL) network connectivity to executive function test performance. We hypothesized that intranetwork connectivity of the DMN and SAL would be uncorrelated to executive function, whereas increased internetwork connectivity would be associated with lower executive function. Methods Twelve physically active and healthy young adults (7 females, 5 males; age: 23.41 ± 2.74 years) were recruited for this study. Participants completed resting-state functional magnetic resonance imaging and three executive function tests administered through the NIH Toolbox Cognitive Battery. Demographically-corrected T-scores were calculated from the Flanker Inhibitory Control and Attention Test (FICA), Dimensional Change Card Sort Test (DCCS), and Pattern Comparison Processing Speed Test (PCPS). The relationship between intra- and internetwork connectivity of the DMN and SAL networks and performance. Results Independently, the DMN and SAL networks demonstrated weak correlations to DCCS (SAL: r = 0.45, p = 0.14; DMN: r = 0.13, p = 0.69), FICA (SAL r = −0.10, p = 0.95; DMN: r = 0.31, p = 0.33), and PCPS (SAL r = 0.10, p = 0.79; DMN: r = 0.22, p = 0.50). However, connectivity between the SAL and DMN networks demonstrated a moderate correlation to FICA performance (r = −0.61, p = 0.02). Conclusions Greater connectivity between the DMN and SAL networks demonstrated the strongest association to attention and inhibitory control performance in physically active, young adults. This relationship suggests greater connectivity of task-negative networks to task-positive networks may interfere with ongoing processing of visuospatial attention and inhibition. Future studies should examine this relationship in athletes who sustain a head injury.

Purpose The main purpose of the study is to explore the auditory selective attention abilities (using event-related potentials) and the neuronal oscillatory activity in the default mode network sites (using electroencephalogram [EEG]) in individuals with tinnitus. Method Auditory selective attention was measured using P300, and the resting state EEG was assessed using the default mode function analysis. Ten individuals with continuous and bothersome tinnitus along with 10 age- and gender-matched control participants underwent event-related potential testing and 5 min of EEG recording (at wakeful rest). Results Individuals with tinnitus were observed to have larger N1 and P3 amplitudes along with prolonged P3 latency. The default mode function analysis revealed no significant oscillatory differences between the groups. Conclusion The current study shows changes in both the early sensory and late cognitive components of auditory processing. The change in the P3 component is suggestive of selective auditory attention deficit, and the sensory component (N1) suggests an altered bottom-up processing in individuals with tinnitus.
