Sensorimotor network segregation declines with age and is linked to GABA and to sensorimotor performance
Aging is typically associated with declines in sensorimotor performance. Previous studies
have linked some age-related behavioral declines to reductions in network segregation. For …

[HTML][HTML] Person-specific and precision neuroimaging: Current methods and future directions
Most neuroimaging studies of brain function analyze data in normalized space to identify
regions of common activation across participants. These studies treat interindividual differences …

Neural distinctiveness declines with age in auditory cortex and is associated with auditory GABA levels
Neural activation patterns in the ventral visual cortex in response to different categories of
visual stimuli (eg, faces vs. houses) are less selective, or distinctive, in older adults than in …
