description: Sample was prepared from the frontal part of the superior frontal gyrus of postmortem brains of 5 humans (from 16 to 20 years, 4 males and 1 females) by pooling equal quantities of total RNA. Samples were obtained from the NICHD Brain and Tissue Bank for Developmental Disorders at the University of Maryland, USA, the Netherlands Brain Bank, Amsterdam, Netherlands and the Chinese Brain Bank Center, Wuhan, China. Informed consent for use of human tissues for research was obtained in writing from all donors or from their next of kin. All subjects were defined as normal by forensic pathologists at the corresponding brain bank. All subjects suffered sudden death with no prolonged agonal state. All samples contained an approximately 2:1 gray matter to white matter volume ratio.
