Spontaneous Events Drive Brain Functional Connectivity?

By Neuroskeptic | May 2, 2015 1:01 pm

A new study claims that Functional Connectivity in MRI Is Driven by Spontaneous BOLD Events

The researchers, Thomas Allan and colleagues from the University of Nottingham (one of the birthplaces of MRI), say that their results challenge the assumption that correlations in neural activity between ‘networks’ of brain regions reflect slow, steady low frequency oscillations within those networks. Instead, they report that the network connectivity is the result of occasional ‘spikes’ of coordinated activation that last only a short time.

Sexist Peer Review and The Role of Editors

By Neuroskeptic | April 30, 2015 4:46 pm

Open access scientific publishing giant PLoS is under fire after an anonymous peer reviewer commissioned by one of their journals advised the (female) authors to “find one or two male biologists” to help improve their manuscript.

The two women are Fiona Ingleby and Megan Head – who, as it happens, I recently interviewed for the PLoS Neuro blog on an unrelated topic. (I should note that PLoS paid me for that review and for the three others I’ve written for them. I have also peer reviewed for PLoS ONE.)

Retraction Watch has more on the case. There’s been a lot said about this on Twitter and elsewhere, and some people have raised the point that if the reviewer were not anonymous, they might have felt more accountable, and would not have written these things.

But to me this misses the point. Anonymous peer review doesn’t mean that no-one is accountable: the editors should be.
