Tissue acquisition for this program project is based on individual tissue transfer agreements between the program project’s principal investigator and several tissue banks: (a) the NICHD Brain and Tissue Bank for Developmental Disorders at the University of Maryland, (b) the Harvard Brain Tissue Resource Center and (c) the Brain Bank for Developmental Disabilities and Aging of the NYS Institute for Basic Research in Developmental Disabilities. Each brain hemisphere number given by the institution that received the donation was used as the only identifier of clinical records and tissue samples. Brain Bank identification of tissue samples is listed in Tables 1 and 2 to keep non-overlapping records of results of examination of brains in different projects and research groups. The Institutional Review Board of the New York State Institute for Basic Research in Developmental Disabilities approved the methods applied in this study.
