Vocabulary Knowledge is Relatively Resilient to Aging: Due Arcuate Fasciculus Patterning?
Vocabulary knowledge exhibits relatively limited decline with age in comparison to many other cognitive functions. We examined whether this relative resilience to aging could be due to the organization of the arcuate fasciculus, a fiber tract where white matter microstructure predicts reading skill development. We show in the Journal of Neuroscience that arcuate fasciculus morphology…

Cingulo-opercular Activity Provides Word Recognition Benefit
Recognizing speech in challenging listening conditions often produces increased activity in frontal cortex, particularly in cingulo-opercular regions, but the significance of this activity has been unclear. This network of frontal cortex is thought to monitor performance and signal when cognitive resources are required to ensure successful performance. Findings from earlier visuospatial studies indicated that…
