PAPER: The Principled Control of False Positives in Neuroimaging
- Current Citation: Bennett CM, Wolford GL, Miller MB. (in press). The Principled Control of False Positives in Neuroimaging. Social Cognitive and Affective Neuroscience. – Abstract: An incredible amount of data is generated in the course of a functional neuroimaging experiment. The quantity of data gives us improved temporal and spatial resolution with which to [...]
Holiday Presents for a Neurogeek
I know this post might be a bit late in the season to make much of an impact on your shopping plans, but if your loved ones can’t get enough neuroscience then here are some thoughts for great gifts. Some are specific to neuroscience, while others are more general and appropriate for any academic. Enjoy! [...]
Quote of the Week – Logothetis
“fMRI is a measure of mass action. You almost have to be a professional moron to think you’re saying something profound about the neural mechanisms. You’re nowhere close to explaining what’s happening, but you have a nice framework, an excellent starting point.” ~ Nikos Logothetis (As seen in Science News)
Live Sectioning of HM’s Brain
The Brain Observatory at UCSD is doing a live feed of the histological sectioning of patient HM’s brain today. The feed will continue for the next two days while they slice through HM’s brain by fractions of a millimeter at a time. You can view the feed yourself at the following link: http://thebrainobservatory.ucsd.edu/hm_live.php. The studies [...]
The War on Fish: False Positive Horror Stories
Citizens of the Interwebs – we are in need of your assistance! My advisor Mike Miller and I have been asked to write a commentary in a major neuroimaging journal that discusses the importance of protecting against false positives (Type I error) in fMRI. This is essentially an extension of the arguments that we made [...]
The Middle Ground in Multiple Comparisons Correction
I got a note last week from a longtime colleague seeking advice on some reviewer comments of their latest paper. In their remarks the reviewer requested that the authors revert the corrected statistical threshold back to an uncorrected level of p < 0.001. The authors were left scratching their heads, wondering how they were going [...]
Neuroimaging Statistics Workshop Videos
The Columbia University Department of Statistics hosted a workshop last month titled “Estimating Effects and Correlations in Neuroimaging Data”. Some great folks stopped by to give talks, including Ed Vul, Nikolas Kriegeskorte, Tor Wager, and Andrew Gelman. They recorded everything into Quicktime movies for those of us who couldn’t stop by – click the link [...]
Quote of the Week – Coggan
“My ignorance of science is such that if anyone mentioned copper nitrate I should think he was talking about policemen’s overtime.” – Frederick Donald Coggan
My first NIH grant proposal
My postdoc adviser Mike Miller and I spent several weeks last April writing a grant proposal requesting ARRA economic stimulus money to do some aging research. Mike has written several grants before, so he is a bit of a pro. In contrast I have never needed to submit a NIH grant proposal. I had steady [...]
