P-values, the other kind

I had to confirm this truly amazing tale I just head from a colleague of mine to believe it. He made important contributions to the […] treatment of erectile dysfunction, and is perhaps best known for an unusual scientific presentation at the 1983 Las Vegas meeting of the American Urological Association, where he removed his trousers to show the audience...

P-values and why you should watch out

Very well written article on p-values and why they should be replaced as standard methods of estimating statistical significance. One researcher suggested rechristening the methodology “statistical hypothesis inference testing”, presumably for the acronym it would yield. http://www.nature.com/news/scientific-method-statistical-errors-1.14700

Acoustic cryptanalysis

This is not neuroscience, but still quite baffling. Did you know your CPU is possibly emitting sounds (at 10KhZ+) that reveal not only activity, but also which type of computations are performed? As has been demonstrated by Genkin et al., in the worst case, this can be used to actually snoop a RSA secret key from a computer decrypting texts...

Bard Ermentrout @ SCNS

Just saw the revered, enigmatic and highly energetic Bard Ermentrout at the SCNS at EPF Lausanne. Besides being quite revealing on his early life hobbies and their effects on his sensory apparatus, he gave a hard to follow but interesting talk on how to perform a dimensional reduction of noisy oscillator neuron models. We formulate a phase-reduction method for a general...

Who is afraid of peer review?

What will happen if you make up a paper, along with authors, affiliations, the data and results. Say you include grave errors that should make any reviewer reject this immediately? Then you submit it to 307 open-access papers and wait for their response. John Bohannon did exactly this and came up with 157 accepted publications. The goal was to create...

On the left-side bias of brain depictions

As demonstrated recently at SFN by Wilson et al., there is a clear left-hemisphere bias of brain depictions. […] An argument based on the prevalence of right-handed illustrators cannot explain the bias seen in photographs of the brain. Some colleagues have suggested that the bias reflects the left-to-right nature of English writing, but we find this argument less than compelling, especially given...

Multi-odor evoked ensemble dynamics

Extending on the milestone paper by Mazor & Laurent, this recently published study by Saha et al. investigates the antennal lobe dynamical odor representations that are evoked by adding a second odor stimulus on top of a background ongoing odor stimulus. Ensemble interference and partial overlaps ensue AND they correlate nicely with locust behavior. Main article @ Nature Neuro This is...

The Thatcher Effect

The Thatcher Effect, it confuses the hell out of me. This is thought to be due to specific psychological cognitive modules involved in face perception which are tuned especially to upright faces.

Network reconstruction chooser

Are you also commonly confronted with the question which network reconstruction method/model to choose? This nice page gives you an overview of the features of different statistical approaches. http://olav.ilo.de/choose_reconstruction/

Your episodic memory is probably distorted

http://www.pnas.org/content/early/2013/11/12/1314373110.abstract The findings suggest that HSAM individuals reconstruct their memories using associative grouping, as demonstrated by a word-list task, and by incorporating postevent information, as shown in misinformation tasks. The findings also suggest that the reconstructive memory mechanisms that produce memory distortions are basic and widespread in humans, and it may be unlikely that anyone is immune. NO ONE IS...
