The specific aim of this study is to improve recovery of visual function after brain injury. A prominent theme of current neuroscience research regarding the sequelae of brain injury posits that activity-dependent plasticity underlies neuro-recovery. If that is the case, there is good reason to believe that neurological changes underling recovery can be facilitated by established means of enhancing cortical activity. Studies suggest that altering cortical excitability may prime or prepare the cortex for subsequent training and furthermore, may improve overall functional outcomes (Webster et al, 2006; Brown & Pilitsis, 2006; Khedr et al, 2005). The working hypothesis of this pilot study is that computer-based visual rehabilitative training (using NovaVision's Vision Restoration TherapyTM; "VRT" software) enhances visual function (defined as an increase in functional visual field) by reinforcing synaptic connections within sensory networks of visual cortex associated with the visual field loss (Kasten et al., 1998; Sabel, 1999). Potentially, this reinforcement can be enhanced by concurrent transcranial direct current stimulation (TDCS) leading in turn, to enhanced visual performance (quantified by the extent of visual field measured by visual perimetry allowing for a direct statistical comparison of visual field change over time and on an individual basis) in patients with partial of complete hemianopic visual field loss caused by brain injury. Both computer based visual rehabilitative training and TDCS are established techniques and this novel approach aims to provide preliminary data regarding the safety and efficacy of a combined intervention.
