The Myth Of “Roid Rage”?

by Neuroskeptic in Neuroskeptic_Discover

Are men who inject testosterone and other anabolic steroids at risk of entering a violent “roid rage“? Many people think so. Whenever a professional athlete commits a violent crime, it’s not long before someone suggests that steroids may have been involved. The most recent example of this is the case of Jonathan “War Machine” Koppenhaver. […]The post The Myth Of “Roid Rage”? appeared first on Neuroskeptic.... Read more »

(False?) Positive Psychology Meets Genomics

by Neuroskeptic in Neuroskeptic_Discover

Academic bunfight ahoy! A new paper from Nick Brown – famed debunker of the “Positivity Ratio” – and his colleagues, takes aim at another piece of research on feel-good emotions. The target is a 2013 paper published in PNAS from positive psychology leader Barbara Fredrickson and colleagues: A functional genomic perspective on human well-being. The […]The post (False?)

Do Narcissists Know They’re Narcissists?

by Neuroskeptic in Neuroskeptic_Discover

According to a provocative paper just published, it’s possible to accurately determine how narcissistic someone is by asking them just one thing. Here’s the question in full: To what extent do you agree with this statement: I am a narcissist? (Note: The word ‘narcissist’ means egotistical, self-focused, and vain.) Answer on a scale from 1 […]The post Do Narcissists Know They’re Narcissists? appeared first on Neuroskeptic.... Read more »

Do Sciences and Humanities Students’ Brains Differ?

by Neuroskeptic in Neuroskeptic_Discover

Scholars on both sides of the science-humanities divide have been known to feel that their counterparts just don’t think in the same way. But could it be that their brains are actually different? Yes, it could, say Japanese neuroscientists Hikaru Takeuchi and colleagues, who have just published a paper about Brain structures in the sciences […]The post Do Sciences and Humanities Students’ Brains Differ? appeared first on Neuroskeptic....

Spotted at last: “Homo economicus”?

by Neuroskeptic in Neuroskeptic_Discover

Are we selfish? Economists like to say that, to a first approximation, we are. In other words, that we tend to seek to maximize our own rewards, in a more or less rational manner. The trouble is that this theory (at least, a straightforward interpretation of it) doesn’t describe how people behave in many situations.

Babylonian Neurology and Psychiatry

by Neuroskeptic in Neuroskeptic_Discover

A fascinating little paper in Brain examines Neurology and psychiatry in Babylon. It’s a collaboration by British neurologist Edward H. Reynolds and Assyriologist James V. Kinnier Wilson. The sources they discuss are almost 4,000 years old, dating to the Old Babylonian Dynasty of 1894 – 1595 BC. Writing in cuneiform script impressed into clay tablets, […]The post Babylonian Neurology and Psychiatry appeared first on Neuroskeptic.... Read more »

fMRI Motion Correction: The Quick and the Dead

by Neuroskeptic in Neuroskeptic_Discover

The infamous dead salmon brain scan study may just have been eclipsed, in the ‘most ghoulish demonstration of a methodological pitfall in fMRI‘ stakes. A new study examines the issue of motion artifacts, a major concern in much neuroimaging research – and it does so by scanning dead people. The new paper has the unwieldy […]The post fMRI Motion Correction: The Quick and the Dead appeared first on Neuroskeptic.... Read more »

Is It Time To Redraw the Map of the Brain?

by Neuroskeptic in Neuroskeptic_Discover

A provocative and important paper just out claims to have identified a pervasive flaw in many attempts to map the function of the human brain. University College London (UCL) neuroscientists Yee-Haur Mah and colleagues say that in the light of their findings, “current inferences about human brain function and deficits based on lesion mapping must […]The post Is It Time To Redraw the Map of the Brain? appeared first on Neuroskeptic....

Another Education Neuromyth Debunked

by Neuroskeptic in Neuroskeptic_Discover

What does neuroscience have to say about the educational value of lectures? Not much, says pedagogist Ken Masters in a lively article just published in Medical Teacher: Nipping an education myth in the bud: Poh’s brain activity during lectures Masters lays into an emerging slice of neurononsense. The claim is that neuroscientists have shown that, […]The post Another Education Neuromyth Debunked appeared first on Neuroskeptic.... Read more »

The FDA’s Antidepressant Warning Didn’t Really “Backfire”

by Neuroskeptic in Neuroskeptic_Discover

We read this week that ‘Black Box’ Warning on Antidepressants Raised Suicide Attempts A so-called “black box” warning on antidepressants that the medications increase the risk of suicidal thinking and behavior in kids may have had a horrible side-effect. New research finds the warning backfired, causing an increase in suicide attempts by teens and young […]The post The FDA’s Antidepressant Warning Didn’t Really “Backfire” appeared first on Neuroskept........

fMRI: Can MVPA Really Help Crack The Neural Code?

by Neuroskeptic in Neuroskeptic_Discover

Multivoxel Pattern Analysis (MVPA) is the latest big thing in the neuroimaging world. MVPA is a multivariate statistical technique that can be applied to fMRI brain scan results as an alternative to conventional univariate methods of finding brain activation. Neuroscientists love MVPA for two reasons: first, it offers more ‘blobs for your buck’ – it […]The post fMRI: Can MVPA Really Help Crack The Neural Code? appeared first on Neuroskeptic....

America’s Most Depressing Jobs?

by Neuroskeptic in Neuroskeptic_Discover

An interesting study just published examines the rates of clinical depression experienced by workers in different jobs. It turns out that people involved in ‘Local and Interurban Passenger Transport’ are most likely to be treated for depression. By contrast, those employed in ‘Amusement and Recreational Services’ are less than half as likely to experience it […]The post America’s Most Depressing Jobs? appeared first on Neuroskeptic....

Tracking Conscious Perception in Real-Time With fMRI?

by Neuroskeptic in Neuroskeptic_Discover

What if it were possible to measure your conscious experience, in real time, using a brain scanner? Neuroscientists Christoph Reichert and colleagues report that they have done just this, using fMRI – although in a limited fashion. Their research has just been published in Frontiers in Neuroscience: Online tracking of the contents of conscious perception […]The post Tracking Conscious Perception in Real-Time With fMRI? appeared first on Neuroskeptic....

At The Right Hand of Sleep

by Neuroskeptic in Neuroskeptic_Discover

When we’re drowsy, and on the point of falling asleep, our awareness of the outside world tends to dim. But a fascinating new paper reports that, for most people, it’s the left side of the world that dims the most.

The Myth of Einstein’s Brain?

by Neuroskeptic in Neuroskeptic_Discover

There was nothing special about Albert Einstein’s brain. Nothing that modern neuroscience can detect, anyway. This is the message of a provocative article by Pace University psychologist Terence Hines, just published in Brain and Cognition: Neuromythology of Einstein’s brain As Hines notes, the story of how Einstein’s brain was preserved is well known. When the […]The post The Myth of Einstein’s Brain? appeared first on Neuroskeptic.... Read more »
