Tens of millions of otherwise healthy people experience age-related cognitive and sensory
impairments. Nevertheless, there are large individual differences in these declines and …

Age-related neural dedifferentiation—a decline in the distinctiveness of neural
representations in the aging brain—has been associated with age-related declines in …

Aging is associated with cognitive impairment, but there are large individual differences in
these declines. One neural measure that is lower in older adults and predicts these …

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 …

Background Aging is often associated with behavioral impairments, but some people age
more gracefully than others. Why? One factor that may play a role is individual differences in …

Several studies have attributed certain visual perceptual alterations in older adults to a likely
decrease in GABA (Gamma Aminobutyric Acid) concentration in visual cortex, an …

Background Aging is often associated with behavioral impairments, but some people age
more gracefully than others. Why? One factor that may play a role is individual differences in …

One factor that might contribute to functional deterioration in healthy older adults is a decline
in the brain's major inhibitory neurotransmitter, gamma-aminobutyric acid (GABA). Previous …

Background Gamma-aminobutyric acid (GABA), the brain's principal inhibitory
neurotransmitter, has been associated with perceptual and attentional functioning. Recent …

Objective: Aging is associated with changes in cortical excitability which may affect motor
learning and cognitive function via selective modulation of gamma aminobutyric acid …
