True story: it took me years to get a passport in my late 20s - at the time I did not have a single piece of identification with my name spelled correctly. All different misspellings. I eventually found a sympathetic clerk who was like 'I can see what happened here'.

Over the years, I have written a few Jupyter/Rmd/Matlab notebooks that attempt to teach some statistical concepts, particularly in neuroimaging. You can find them here: www.mrc-cbu.cam.ac.uk/people/rik.h..., though I will say a bit more about each one in a number of posts over next few days.

With some trepidation, I'm putting this out into the world:
gershmanlab.com/textbook.html
It's a textbook called Computational Foundations of Cognitive Neuroscience, which I wrote for my class.
My hope is that this will be a living document, continuously improved as I get feedback.

Five years ago, I had a very sick child and referrals to several pediatric medical specialists and tests in a building a few blocks from the US Capitol. The kid got a diagnosis. Treatment worked. But for me, January 6, 2020 means memories of rescheduling medical appointments for a very sick child.

So I made a little simulation where there is no actual discordance, i.e. the underlying values from which the CBF, CBV, BOLD, and T2* are measured all move in lockstep. With zero noise this gives you zero discordant voxels (nice little diagonal line).
