PAPER: How reliable are the results from functional magnetic resonance imaging?
- Current Citation:
Bennett CM, Miller MB. (in press). How reliable are the results from functional magnetic resonance imaging? Annals of the New York Academy of Sciences.
- Abstract:
Functional magnetic resonance imaging is one of the most important methods for in vivo investigation of cognitive processes in the human brain. Within the last two decades [...]
Quote of the Week – Pashler
“It’s hellishly complicated, this data analysis, and that creates great opportunity for inadvertent mischief.” – Hal Pashler (As seen in Science News)
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 evaluate [...]
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)
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 Internet Found the Atlantic Salmon
The last 72 hours have seen an incredible increase in traffic here at prefrontal.org. To sum it up in a single sentence: the site has received as many hits in the last three days as it has during the past two years. Yeah, really. My activity graph on the Wordpress Dashboard looks [...]
The Story Behind the Atlantic Salmon
The Atlantic Salmon fMRI poster has garnered a fair amount of attention since its presentation at the Human Brain Mapping conference last June in San Francisco. So far the reaction from other researchers has been almost unanimously positive. A sizable number of people stopped by the poster while it was displayed and Rainer [...]
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 [...]
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 [...]
Atlantic Salmon – MRI Data
There have been some requests for the T1-weighted high-resolution anatomical MRI data of the Atlantic Salmon. Click on the link below and you can download the files in the ANALYZE file format.
