By the third month post-lesion, further recovery is generally considered impossible because the pathway from retina to primary visual cortex is irreparable, and according to the classical model of visual neuroanatomy, this pathway is the sole carrier of most visual information to the cortex. Rehabilitation therefore focuses on the development of compensatory strategies to cope with disability, rather than restoration of function. Recent discoveries in neuroanatomy, adult plasticity, and perceptual learning, along with limited success in several paradigms of aggressive visual retraining, provide ample reasons to challenge this view of post-chiasmal vision loss. This study seeks to inform the possible mechanisms of recovery in one retraining paradigm, motion direction discrimination training. Using fMRI, brain responses to motion stimuli were assessed pre- and post-training in a small sample of hemianopes and quadrantanopes. Post-training, activity increased in perilesional cortex relative to pre-training levels, and this effect paralleled behavioral improvements. The effect was limited to retrained regions of the blind visual field, ruling out spontaneous recovery. ]]> Tim Martin  (Assistant Professor of Psychology – Kennesaw State University) – Center for Advanced Brain Imaging, Conference Room

In a study examining individual differences in episodic memory in young adults, we found that individual differences in self-initiated use of verbal and visual encoding strategies are associated with individual differences in memory performance. Use of verbal encoding strategies is correlated with activity in a network of brain regions that includes prefrontal regions associated with controlled verbal processing, while use of visual strategies is correlated with activity in a network of brain regions that includes an extrastriate region associated with object processing. Activity in brain regions associated with use of these effective strategies is also correlated with memory performance. Age-related changes in self-initiated use of encoding strategies could also play an important role in changes in episodic memory and brain activity in older adults. Behavioral studies have suggested that older adults are less likely than young adults to spontaneously use effective encoding strategies during intentional encoding. In addition, age-related changes in brain activity during intentional encoding have been reported in prefrontal regions associated with self-initiated use of effective encoding strategies in young adults. To further explore the role that age-related changes in self-initiated encoding strategy use may play in age-related changes in episodic memory and brain activity in prefrontal cortex, we recently conducted a cognitive training study in which older adults were taught to use semantic (meaning-based) encoding strategies. Training older adults to use semantic encoding strategies substantially improved their ability to consciously recollect studied words. Older adults reported greater self-initiated use of semantic encoding strategies following cognitive training, and were less likely to report not using any encoding strategy. Brain activity in left inferior prefrontal regions associated with semantic processing increased following cognitive training, and individual differences in training-related changes in brain activity in these regions were associated with individual differences in training-related changes in memory performance. ]]> Brain Imaging Seminar Series:  Brenda Kirchhoff , University of Missouri-St. Louis (3:00 p.m.) Center for Advanced Brain Imaging (Conference Room)
