Vision and Brain Development for CVI
Fundamentals in Vision and Brain Development for Cerebral/Cortical Visual Impairment (CVI)
Abstract
Fundamentals in Vision and Brain Development for Cerebral/Cortical Visual Impairment (CVI)
In this four-part seminar, information will be presented that is pertinent to understanding how we can evaluate neuroplasticity and functional vision in individuals with CVI. It will provide information on how vision is processed in the brain and how this process may be interrupted in atypical brain development. The second session will cover the topic of neuroplasticity: identify what it is, what evidence there is for it in the context of sensory impairment, and discuss the potential for neuroplasticity in CVI. After lunch, we will delve into learning about the principles of evidence-based approaches to evaluating functional vision. The final session will share how researchers are using neuroimaging to better understand the relationship between the brain and the observed visual dysfunctions common in individuals with CVI. The day will be rounded off with a time of discussion.
