Dr. John Hart Jr. received $2,022,497 from the Congressionally Directed Medical Research Program for his research on Treatment of Verbal Retrieval Deficits in Mild Traumatic Brain Injury with High Definition Transcranial Direct Current Stimulation. Dr. Hart plans to use the grant to test the efficacy of targeting pre-supplementary motor areas (preSMA) with HD transcranial Direct Current Stimulation (tDCS) to treat verbal retrieval deficits in veterans with remote mild traumatic brain injury histories and subjective complaints of verbal retrieval deficits.
