Mechanisms of Photophobia in Mild Traumatic Brain Injury in Human Subjects: Therapeutic Implications
The purpose of this grant is to identify the mechanisms responsible for generating photophobia in patients who have suffered mild traumatic brain injury (mTBI). Currently, estimates indicate that this painful condition persists in about 60% of those who suffered from blast-related traumatic brain injury and 30% of those who suffered non-blast-related concussive injuries.
SL-CN: Harnessing the Power of Drawing for the Enhancement of Learning across Levels of Vision Function
This Science of Learning Collaborative Network brings together researchers and experts from the Smith-Kettlewell Eye Research Institute, University of Bamberg (Germany), Columbia University and Emory University to investigate how the visual art of drawing can enhance learning. Underlying learning principles and neural mechanisms will be considered, and how these can be harnessed for real-life learning enhancement. Though humans have been drawing for at least 30,000 years, little is understood about brain processes involved in this activity.
Recent scientific findings about art and drawing suggest that drawing can facilitate learning in a wide variety of domains. The proposed collaboration will develop an interdisciplinary research program aimed at harnessing the power of drawing to enhance learning across fields of intellectual endeavor.
Successful navigation requires the development of an accurate and flexible mental, or cognitive, map of the navigational space and of the route trajectory required to travel from the current to the target location. The Cognitive-Kinesthetic (C-K) Rehabilitation Training that we have developed in the preceding period utilizes a unique form of blind memory-guided drawing to develop cognitive mapping to a high level of proficiency.
Recent studies have established that a high proportion of patients diagnosed with mild (or diffuse) traumatic brain injury (mTBI) exhibit binocular vision dysfunctions, particularly, deficiencies in the binocular coordination of eye movements.
We propose a multidisciplinary approach to effective spatiomotor rehabilitation in blindness and visual impairment. For those who have lost vision, the eye-hand coordination normally available for the manipulation of objects for everyday activities is unavailable and has to be replaced by information from other senses
