Briefly, the authors repeatedly, transiently opened the blood-brain barrier (BBB) of an animal model of AD using scanning ultrasound. They observed that AD-like behavioral and brain symptomology was reduced in the treated animals. They su

Both valid points, but this failure-to-replicate does erode some confidence in the general notion of embodied cognition (and I believe deservedly so because these phenomena have always seemed rather incredible). Much of Kahneman's oth

Like you, I learned Logo on an Apple ][ in the '80s. Apart from some dabbling in between, I wouldn't pick up programming in a serious way until grad school. Despite the long gap, that early start made a huge difference for me, a

Title annotated for general clarity as Dr. Nichols's original (in parentheses) is a bit opaque. Also, that should be a lower-case "f" on "fMRI"; I believe that the title was the victim of autocapitalization.

Sort of. The rebuttal (by Flandin and Friston) suggests that properly-applied parametric statistics of the kind they favor are valid. Eklund et al. wouldn't disagree with that because their own findings support it, but they would p

I completely agree that this can be frustrating. For what it's worth, the data from a research study aren't necessarily going to be clinically informative to a GP or even to a radiologist. Structural MRI data could potentially b

Flaundin & Friston's response is interesting because it essentially endorses the findings of Eklund et al. (except for one element of the Eklund analysis that they suggest is a modest error). F&F believe that by setting one pa

The dead salmon article is a bit of a red herring here. It's a clear demonstration that a shoddy statistical approach can undermine fMRI findings. Critically, the implications of the current paper extend to even research that has bee

This is right and wrong: AFNI's 3dClustStim did contain a specific bug (since corrected) and is used for fMRI analysis, but the problem that the authors identified is more general than that and encompasses all of the tested packages.

You're correct that the main finding reflects flawed statistical assumptions made by the major neuroimaging packages (or so these authors contend), but they did uncover a specific bug in one of the three packages (AFNI): "... a 15

Very cool! I've always been fascinated by lighter-than-air vehicles, and I'm excited to see that the technology is still being developed. For anyone who's interested, the history of the field is littered with odd false star

Seconded — Miguel's blog is terrific! Major chunks of my (very simple) website's code bear a suspicious resemblance to his examples.

Striking, isn't it? I ran across his work when taking cog psych/cog neuro courses. Arcimbaldo's paintings provide a great demonstration of face perception and — one could argue — face-seeking that our brains perform with no

I've tried remapping Caps Lock, but I find that the stretch to hit that key eventually irritates my ulnar nerve. I'll stick with "jk" (or "ii" on Colemak).
