Multi-voxel pattern analysis (MVPA) is an increasingly popular approach for analyzing the results of fMRI scanning experiments that measure brain activity. MVPA searches for patterns of activation that correlate with a particular mental state. This is called ‘decoding’ neural activity.
Now a new paper in the Journal of Neuroscience from Caltech neuroscientists Julien Dubois et al. reports that MVPA is unable to decode certain kinds of information, even though single-unit recordings confirm that the information is present in brain activity.
In an interesting short paper just published in Trends in Cognitive Science, Caltech neuroscientist Ralph Adolphs offers his thoughts on The Unsolved Problems of Neuroscience.
Last week we learned about the strange goings-on at two journals edited by the autism researcher, Johnny Matson. Matson and his team ‘stepped down’ after accusations of improper peer review processes.
This reminded me of another case of unusual behavior at an academic journal: Surgical Neurology International (SNI), published by Medknow/Wolters Kluwer. I’ve been meaning to blog about this for a while, and now seems like a good time.
In a new paper, a group of MIT researchers argue that science is producing PhDs in far greater numbers than there are available tenured jobs for them to fill.
I’m a regular reader of Jeffrey Beall’s invaluable Scholarly OA blog. Earlier this week Beall blogged about a dubious-looking new ‘predatory’ journal called International Journal Online of Humanities (IJOHMN). I took a look and noticed that one of their papers is called Leaders Produce Teamwork Organizations.
How do people in different cultures view history? Around the globe, who are regarded as the best and worst historical figures? A new survey out now in PLoS ONE reveals the patterns of world opinion: “Heroes” and “Villains” of World History across Cultures.
What do Hennessy, Jack Daniels, and Everclear have in common? According to a rather fascinating new study, these three brands are especially popular with those teenage drinkers who get into booze-related fights.
This is my fourth post on ‘quantum resonance spectrometry’ (QRS), a strange medical technology that seems to be becoming increasingly popular in China. Proponents claim that QRS can quickly and painlessly diagnose almost any disease. However, as I discussed last time, the technology has a dubious history.
But we shouldn’t focus on the past. The important question is: how well do today’s QRS devices work? In this post I’ll look at some examples of the technology in action.
When scientists disagree about something, the two sides of the argument often come to form separate communities, with scientists collaborating with others on their “team” while avoiding working with their “opponents”. But is there a better way?
