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.

Harnessing the Power of Drawing for the Enhancement of Learning across Levels of Vision Function
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.

Advanced Spatiomotor Rehabilitation for Navigation in Blindness & Visual Impairment
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.

Alleviating interocular suppression by high-attention demand training in amblyopia
The goal of this project is to test a hypothesis that whether or not training patients to pay more attention to the input from the amblyopic eye can overcome interocular suppression to treat amblyopia.

Learning in the Sighted and the Blind through Different Sensory Modalities: Structure and Dynamics of Cortical Reorganization
This project focuses on the emerging area of the neuroscience of art learning. It addresses the important issue of how the brain learns complex skills, specifically the process of drawing, through two different sensory modalities. Visual art, and drawing in particular, engages an orchestrated...
