DESCRIPTION:“Population Neuroimaging”\n\nThomas Nichols\, Oxford University
 \n	Tuesday January 21\, 12-1pm\n	Montreal Neurological Institute\, Jeanne Ti
 mmins Amphitheatre\n\nAbstract: Brain imaging studies have traditionally s
 truggled to break into 3-digit sample sizes: e.g.\, a recent Functional Ma
 gnetic Resonance Imaging (fMRI) meta-analysis of emotion found a median sa
 mple size of n=13. However\, we now have a growing collection studies with
  sample sizes with 4-\, 5- and even 6-digits. Many of these 'population ne
 uroimaging' studies are epidemiological in nature\, trying to characterise
  typical variation in the population to help predict health outcomes acros
 s the life span.\n\nI will discuss some of the challenges these studies pr
 esent\, in terms of massive computational burden but also in ways that the
 y expose shortcomings of existing mass univariate techniques. I will also 
 discuss how these datasets present intriguing methodological problems here
 tofore absent from neuroimaging statistics. For example\, the 'null hypoth
 esis fallacy' is how H0 is never strictly true\, and yet with 100\,000 sub
 jects you'll eventually find some effect even if it is meaningless. This m
 otivates work spatial confidence sets on meaningful effect sizes (instead 
 of thresholding test statistic images)\, providing intuitive measures of s
 patial uncertainty.\n
