"Theory of mind is not theory of emotion"

by Paul Whiteley in Questioning Answers

A rather interesting paper by Beth Oakley and colleagues [1] (open-access might be available here) appeared recently providing a "cautionary note on the Reading the Mind in the Eyes Test" [2], one of the premier assessments thought to offer a performance-based measure "involving mental state attribution and complex facial emotion recognition from photographs where only the eye region of the face is available."Most people with some knowledge about autism research history will have heard about the........

In cells, some oxidants are needed

by Dr. Jekyll in Lunatic Laboratories

Within our bodies, high levels of reactive forms of oxygen can damage proteins and contribute to diabetic complications and many other diseases. But some studies are showing that these reactive oxygen species (ROS) molecules sometimes can aid in maintaining health--findings now boosted by a surprising discovery by researchers.

What To Do About Software Errors in fMRI?

by Neuroskeptic in Neuroskeptic_Discover

Last month we learned that a problem in commonly used fMRI analysis tools was giving rise to elevated rates of false positives. Now, another issue has been discovered in an fMRI tool. The affected software is called GingerALE and the 'implementation errors' are revealed in a new paper by Simon B. Eickhoff et al., the developers of the package.





GingerALE is a meta-analysis tool, that offers the ability to combine the results of multiple fMRI studies to assess the overall level of evide... Read more »

Brawn, Brain and Beauty

by Aurametrix team in Aurametrix Blog

In the future all humans will be tall and beautiful look-alikes, as in GATTACA. Or they will split into frail beauties and sturdy beasts, as described in H. G. Wells' The Time Machine. British evolutionary psychologist Oliver Curry and paleoanthropologist Matthew Skinner believe in the possibility of similar scenarios, based on either the rich and poor divide ("gracile" vs "robust" species) or climate change-related evolution (pale hairy giants vs aquatic and space humans). The change may b........

Are Teaching and Learning Coevolved?

by Joshua Fisher in Text Savvy

Discussions in education are increasingly focused on "how students learn," and it seems to be widely accepted that teaching should adjust itself to what we discover about this. But if teaching is as natural a human faculty as learning, then this may be only half the story. How students (naturally) learn might be caused, in part, by how teachers (naturally) teach, and vice versa. And learners perhaps should be asked to adjust to what we learn about how we teach as much as the other way ........ Read more »

'I miss you so much': How Twitter is broadening the conversation on death and mourning

by Dr. Jekyll in Lunatic Laboratories

Death and mourning were largely considered private matters in the 20th century, with the public remembrances common in previous eras replaced by intimate gatherings behind closed doors in funeral parlors and family homes. But social media is redefining how people grieve, and Twitter in particular -- with its ephemeral mix of rapid-fire broadcast and personal expression -- is widening the conversation around death and mourning.

What are we getting wrong in neuroscience?

by neurosci in Neuroscientifically Challenged

In 1935, an ambitious neurology professor named Egas Moniz sat in the audience at a symposium on the frontal lobes, enthralled by neuroscientist Carlyle F. Jacobsen's description of some experiments Jacobsen had conducted with fellow investigator John Fulton. Jacobsen and Fulton had damaged the frontal lobes of a chimpanzee named "Becky," and afterwards they had observed a considerable behavioral transformation. Becky had previously been stubborn, erratic, and difficult to train, but post-operat........ Read more »

Polycystic ovary syndrome (PCOS) and risk of psychiatric disorder

"Polycystic ovary syndrome (PCOS) is an endocrine disorder affecting 5-15% of reproductive-aged women and characterized by high levels of circulating androgens."OK, go on."Women with PCOS had higher risks for a range of psychiatric disorders not shown before. Elevated risk in their siblings suggests shared familial factors between PCOS and psychiatric disorders."So said the findings reported by Carolyn Cesta and colleagues [1] who using Swedish national register data concluded that there ma........

Cloth masks offer poor protection against air pollution

by Dr. Jekyll in Lunatic Laboratories

Results of a new study by environmental health scientists suggest that inexpensive cloth masks worn by people who hope to reduce their exposure to air pollution vary widely in effectiveness and could be giving users a false sense of security, especially in highly polluted areas.

The Brain That Goes Through Phases: Temporal Metastates in fMRI

by Neuroskeptic in Neuroskeptic_Discover

Do you ever feel like your brain is stuck in a rut? A new study from neuroscientists James M. Shine and colleagues reveals the existence of 'temporal metastates' in human brain activity. These metastates are modes or patterns of activity that can persist over days, weeks or even months at a time, and they seem to be related to fluctuations in energy levels and attention.

The authors made use of a unique fMRI dataset, namely the results of repeated scanning of neuroscientist Russ Poldrack's br... Read more »

Psychopaths brains work differently—at least when  they are criminal psychopaths

by Rita Handrich in The Jury Room

This will shock you, or maybe relieve you: Psychopaths are different from the rest of us. Here’s another article saying there are measurable differences in how the brains of how criminal psychopaths work (and look) when compared to non-criminal psychopaths (those who have psychopathic traits but have not been convicted of criminal offenses) and non-psychopaths.

Childhood inflammation and hypomanic symptoms in young adulthood?

"Higher levels of systemic inflammatory marker IL-6 in childhood were associated with hypomanic symptoms in young adulthood, suggesting that inflammation may play a role in the pathophysiology of mania."That was the conclusion reached by Joseph Hayes and colleagues [1] (open-access available here) who drew on data derived from the excellent resource that is ALSPAC ("Charting the health of 14,500 families in the Bristol area to improve the health of future generations").

Neural stem cells control their own fate

by Dr. Jekyll in Lunatic Laboratories

To date, it has been assumed that the differentiation of stem cells depends on the environment they are embedded in. A research group now describes for the first time a mechanism by which hippocampal neural stem cells regulate their own cell fate via the protein Drosha.

Sorry, I Don't Drink

by Mark Lasbury in As Many Exceptions As Rules

Koalas don’t drink a lot of water, but the spinifex hopping mouse and kangaroo rat put him to shame. They never drink. What water they need they get from the seeds they eat and from the fact that they conserve water amazingly well – including the water that they produce during metabolism. Adult mayflies don’t drink either – they don’t have working mouthparts! Of course, some only live a few minutes as adults, so it may not be that big a deal.... Read more »
