Currently, the Human Brain Collection Core (HBCC) resources include brains from individuals with the following diagnoses (numbers of subjects listed in parentheses): Bipolar disorder (152), Non-psychiatric controls (311), Schizophrenia and schizoaffective disorder (186), Substance Abuse (81), Major depressive disorder (256), Other psychiatric diagnoses (123), Neurological disorders (52), Not diagnosed (63). The total number of subjects in the database is 1598. From Oct 1, 2018, until July 31, 2019 we collected 61 brains through the DC and Northern and Central VA Medical Examiners Offices. Number of cases per diagnosis: 2 ADHD 1 Autism 1 Bipolar Disorder 1 Control 4 Major depressive disorder 2 Neurological 5 Substance use disorder 1 Undetermined 44 pending Other resources include: -cDNA libraries constructed from dorsolateral prefrontal cortex (DLPFC), hippocampus, anterior cingulate cortex (ACC) and subgenual anterior cingulate cortex (sgACC), and dura from hundreds of subjects with psychiatric disorders and controls -microarray expression and genotyping data (publicly available at dbGAP accession ID: phs000979.v2.p2) from DLPFC, hippocampus and dura -frozen sections (14 um thick) mounted on slides (DLPFC from 32 patients with schizophrenia and 63 controls), -formalin-fixed coronal slices (approximately 15 mm thick) of a single hemisphere from 15 controls, 10 patients with schizophrenia, 5 with major depression, 4 with bipolar disorder. -Fibroblasts derived from postmortem dura: 450 -Whole genome sequencing, RNA sequencing, and Chip-sequencing (acetylation and methylation marks) data for DLPFC of 400 subjects (publicly available at dbGAP accession ID: phs000979.v2.p2, on the CommonMind Consortium portal and on the PsychEncode resource page: http://resource.psychencode.org/) -RNA sequencing data from 200 individuals from the subgenual ACC, 219 from the Superior Temporal Gyrus and 311 from the dorsal anterior cingulate will become available soon. We share information with Neurobiobank (NBB). Our inventory of cases can be searched through the Neurobiobank website (https://neurobiobank.nih.gov/). We obtain detailed quantitative electronic toxicological data from NMS on hundreds of our specimens and share them with NBB. We implemented a transition to ICD10 codes that makes our diagnostic definitions easily sharable with NBB. We have unified the naming and reporting of brain regions/specimens available in HBCC with the goal of making these fields easily available to NBB and investigators. The number of requests for tissue/data in the last year increased compared to the same period last year. We have distributed samples and data to investigators for more than 180 approved projects since the inception of the HBCC, most in the last 2 years. In the last year, we have responded to 25 requests for tissue and 6 requests for letters of support on grant applications. The tissue distribution requests that are still in progress or have been initiated in the last year are: 1.
