Changes in these features have been identified in many neurol ogical and psychiatric disorders such as Alzheimer's disease\, Parkinson's disease\, schizophrenia\, major depression\, autism\, bipolar disorder as well as drug addiction. Understanding the genetic basis of these brain tr aits will have high relevance to neurological\, psychiatric\, degenerative and developmental disorders.\n\n \n\nIn 2017 the UK Biobank released high quality brain imaging data on 10\,000 subjects. A fully automated process ing pipeline has been developed for UK Biobank that produces both processe d images as well as image-derived phenotypes (IDPs)\; this generates thous ands of distinct individual measures of brain structure and function. Exam ple IDPs include the volume of specific brain structures\, the strength of connectivity between pairs of brain regions and the dispersion of fibers in a given white-matter tract.\n\nUK Biobank has also collected genome-wid e genetic data on every participant using a purpose-designed genotyping ar ray. A custom quality control\, phasing and imputation pipeline was develo ped to address the challenges specific to the experimental design\, scale\ , and diversity of the UK Biobank dataset. The genetic data was released t o researchers with approved access in July 2017 and consists of ~96 millio n genetic variants in ~500\,000 study participants.\n\nThe talk will descr ibe the joint analysis of the genetic and brain imaging datasets available from UK Biobank. This will include a decription of some of the novel meth ods we have developed to cope with the scale of the genetic and brain imag ing data\, as well as a description of the main findings of the study so f ar.\n DTSTART:20180322T160000Z DTEND:20180322T170000Z LOCATION:521\, McIntyre Medical Building\, CA\, QC\, Montreal\, H3G 1Y6\, 3 655 promenade Sir William Osler SUMMARY:QLS Featured Seminar Series - Dr. Jonathan Marchini URL:/qls/channels/event/qls-featured-seminar-series-dr -jonathan-marchini-285583 END:VEVENT END:VCALENDAR
