  1. Hamilton R, Chrysikou E, Coslett B. Mechanisms of aphasia recovery after stroke and the role of noninvasive brain stimulation. Brain Lang. 2011;118:40-50 pubmed publisher
    ..We further argue that TMS and tDCS are potentially promising tools for enhancing functional recovery of language and for further elucidating mechanisms of plasticity in patients with aphasia. ..
  2. Harvey D, Mass J, Shah Basak P, Wurzman R, Faseyitan O, Sacchetti D, et al. Continuous theta burst stimulation over right pars triangularis facilitates naming abilities in chronic post-stroke aphasia by enhancing phonological access. Brain Lang. 2019;192:25-34 pubmed publisher
  3. Marulanda Londoño E, Bell M, Hope O, Leacock R, O Carroll C, Posas J, et al. Reducing neurodisparity: Recommendations of the 2017 AAN Diversity Leadership Program. Neurology. 2019;92:274-280 pubmed publisher
    ..Ultimately, the goal of tackling neurodisparity is perfectly aligned with the mission of the AAN: to promote the highest-quality patient-centered neurologic care and enhance member career satisfaction. ..
  4. Patel S, Lee E, Xie S, Law A, Jackson E, Arnold S, et al. Phosphorylated tau/amyloid beta 1-42 ratio in ventricular cerebrospinal fluid reflects outcome in idiopathic normal pressure hydrocephalus. Fluids Barriers CNS. 2012;9:7 pubmed publisher
    ..Moreover, preliminary evidence suggests that CSF biomarkers of AD may prove useful for stratifying shunt prognosis in patients being evaluated and treated for this condition. ..
  5. Gill J, Shah Basak P, Hamilton R. It's the thought that counts: examining the task-dependent effects of transcranial direct current stimulation on executive function. Brain Stimul. 2015;8:253-9 pubmed publisher
    ..This finding has direct relevance to the use of tDCS as an investigative tool in cognitive neuroscience and as a therapy. ..
  6. Price A, McAdams H, Grossman M, Hamilton R. A Meta-analysis of Transcranial Direct Current Stimulation Studies Examining the Reliability of Effects on Language Measures. Brain Stimul. 2015;8:1093-100 pubmed publisher
    ..g., verbal fluency measures and left prefrontal cortex, P = 0.035). The results indicate that single-session tDCS produces significant and reliable effects on language measures in healthy adults. ..
  7. Shah Basak P, Chen P, Caulfield K, Medina J, Hamilton R. The role of the right superior temporal gyrus in stimulus-centered spatial processing. Neuropsychologia. 2018;113:6-13 pubmed publisher
    ..Notably, accuracy or errors were not influenced by SMG stimulation compared to vertex. In line with our predictions, the findings provide compelling evidence for right STG's involvement in healthy stimulus-centered spatial processing. ..
  8. Gervits F, Ash S, Coslett H, Rascovsky K, Grossman M, Hamilton R. Transcranial direct current stimulation for the treatment of primary progressive aphasia: An open-label pilot study. Brain Lang. 2016;162:35-41 pubmed publisher
    ..Our encouraging results indicate that larger, sham-controlled studies of tDCS as a potential intervention for PPA are warranted. ..
  9. Lee Y, Zreik J, Hamilton R. Patterns of neural activity predict picture-naming performance of a patient with chronic aphasia. Neuropsychologia. 2017;94:52-60 pubmed publisher
    ..By using an alternative approach, we extend current evidence for compensatory naming processes that operate through spatially differential patterns within the reorganized language system. ..
