This study will examine several young adults post-hemispherectomy to better understand their performance in social skills, memory, and higher cognitive functions using neuropsychological testing. The discipline of neuropsychology studies the structure and function of the brain as they relate to specific psychological processes and behaviors.  It is seen as a clinical and experimental field of psychology that aims to study, assess, understand and treat behaviors directly related to brain functioning.

Lead researchers:

Dr. Lynn K. Paul has been a Visiting Associate at Caltech since 2004. Her primary research focus is the role of the corpus callosum in emotions and social cognition. Dr. Paul is heading the Caltech Corpus Callosum Research Program and an inter-institutional research consortium on agenesis of the corpus callosum (AgCC).

Dr. Warren S. Brown is Director of the Lee Edward Travis Research Institute and Professor of Psychology, Department of Clinical Psychology, at Fuller Theological Seminary.  Currently, he is most actively involved in neuroscience research related to the cognitive and psychosocial disabilities in a congenital brain malformation called agenesis of the corpus callosum. Brown has also studied callosal function in dyslexia, Attention Deficit Hyperactivity Disorder, multiple sclerosis, and Alzheimer’s disease, and has done research on brain wave changes associated with aging and dementia, language comprehension, dialysis treatment for kidney disease, and attention deficits in schizophrenia.

Participants’ travel, room, and board, including one companion, will be fully-funded by The Brain Recovery Project.
