I feel it is charitable to call the final sentence of the abstract a wild speculation:"The observations suggest that male brains are structured to facilitate connectivity between perception and…

Dear communitya study recently published by Hänggi and colleagues of the University of Zurich, Switzerland, questioned the sex effects reported by Ingalhalikar and colleagues...

A new study published suggests that the effects reported are driven by brain size and not by sex per sehttp://journal.frontiersin...
Until (if) the authors provide effect sizes or raw data, the best that can be done is converting from t and degrees of freedom to Cohen's d. This has been done here (though only for two reported…
A comment has been published in PNAS: http://doi.org/10.1073/pnas.1323319111which, among other things, mentions the lack of reported effect size estimates...
Allison Stelling | Dec 05 2013 12:16 ESTThis paper has generated quite a lot of commentary in the press. Here's a sampling of some of the coverage thus far, mostly from the discussion occurring on…
It is surprising that the authors did not test whether differences in propensity for movement might be driving the group differences. Such differences have been observed in resting state functional…
Firstly, it's hard to draw many conclusions about what the researchers were actually measuring, because the method and operationalization of measurement is not mentioned...
"Such differences [in propensity for movement] have been observed in resting state functional MRI data between males and females"Do you have the citation for this? It is intuitive that age or autism…
DTI may be even more sensitive to motion than is BOLD-based fMRI. DTI sequences have additional in-sequence sources of motion-related error (strong diffusion encoding gradients, and use of GRAPPA…
I wonder whether or not the authors took the obvious precaution of presenting a lot of images in random order to each other. it would be very interesting to know how often they were able to tell the…
What are the female and male brain pictures the popular media used? Are they based on averages of some kind? If so, why do the bottom pictures in Figure 2 of the article look considerably less…
That's interesting. But the hype certainly carried the suggestion that the differences were clear, and that consequently prediction would be possible...
David: The authors did not claim to be able to classify the sex of participants from their brain scans; their analysis had the much more modest goal of showing that there were significant differences…
Hi Peer 2, No harm done. I'll take the opportunity to clarify. I actually cited that paper for both points, which are equally important in the present discussion, I think...
Ah, right there in Figure 1. Males move more than females. I missed that on my cursory glance at the paper and assumed you cited it for the stability point...
Hi Peer 2: Yes, it was at the end of that sentence: (Van Dijk, Sabuncu
Some questions for the authors:It would be useful to have more information about the participants in this study. How were they recruited? Is any information available on their levels of cognitive…
