Alyssa Galganov fNIM lab receives a shout-out for our recent publication on age-related neural dedifferentiation. Neural dedifferentiation refers to the reduction of neural selectivity for specific classes of stimuli, a phenomenon which can be observed in older age. The study has observed that selective patterns of activity are subsequently associated with poorer memory performance. However, the relationship … Read more

In older adults, changes in brain structure and function are associated with declines in some aspects of cognitive performance. One phenomenon that may play an important role in cognitive aging is “neural dedifferentiation” – the finding that older adult brains tend to show less selective patterns of neural activity for certain types of information. This … Read more
