Brain Shape and Personality Type

by William Yates, M.D. in Brain Posts

Personality has often been conceptualized a a human feature shaped largely by nurture and environment.Unlike major neuroscience medicine disorders, personality features have been considered less influenced by brain structure and genetic influences.A recent brain structure (morphology) study puts these assumptions at risk.Roberta Riccelli along with colleagues in Italy and Florida State University studied brain structural features across 507 participants in the Human Connectome Project.All subjec........

"Schizophrenia confers a high endogenous risk for diabetes"

by Paul Whiteley in Questioning Answers

"Schizophrenia confers a high endogenous risk for diabetes, and the risk is further increased by both first-generation and second-generation antipsychotics."So concluded Anto Rajkumar and colleagues [1] who relied on participant data in the thousands derived from several of those very helpful Scandinavian population registries (this time in Denmark) to add some further science to the idea that psychiatric diagnoses like schizophrenia seem to carry an elevated risk for all-manner of somatic ........

Hyperuricemia present in both medicated and unmedicated kids with autism

by Paul Whiteley in Questioning Answers

I was intrigued to read the findings reported by Natchaya Vanwong and colleagues [1] talking about the presence of hyperuricemia - an excess of uric acid in the blood - in their cohort of children and young adults diagnosed with an autism spectrum disorder (ASD). Intrigued not only because the authors discuss how the use of the atypical antipsychotic risperidone might *correlate* with elevations of uric acid but also how: "Hyperuricemia was present in 44.70% of risperidone-naïve patients w........

Preprints – the way forward for rapid and open knowledge sharing

by SciELO in SciELO in Perspective

Preprints – versions of academic articles that have not yet been formally peer-reviewed before publication – are gaining acceptance in the academic world. They deliver open access as well as speedy publication, and their decades old success in physics has spurred on their spread in other disciplines. The development of preprints is accelerating; important funding agencies are in support of them, and also SciELO is planning to set up a preprint server for authors in Latin America and the Glob........

Simple Jury Persuasion: A psychology vaccine for climate  change disinformation

by Doug Keene in The Jury Room

Disinformation is everywhere you turn these days, so we need good tools to debunk those “alternative facts”. Last year we wrote about a strategy to combat distrust of science by using the concept of the “gateway belief”. While that paper received criticism from a well-known law professor, over at the Cultural Cognition blog, the same […]... Read more »

Autism and a 'clear' reduction of behavioural severity in cases diagnosed

"This study provides the first clear evidence of a reduction over time in the behavioral severity of individuals diagnosed with Autistic Disorder during a period of stability in diagnostic criteria."So said the study findings reported by Andrew Whitehouse and colleagues [1] (a man not afraid to make waves when it comes to thinking about autism or about approaches to intervention) looking at "whether there were changes over time in the qualitative and quantitative phenotype of individuals wh........

Split Brain, Undivided Consciousness?

by Neuroskeptic in Neuroskeptic_Discover

A new paper challenges a decades-old theory in neuroscience: Split brain: divided perception but undivided consciousness



According to the famous work of Roger Sperry and Michael Gazzaniga, "split brain" patients seem to experience a split in consciousness: the left and the right side of their brain can independently become aware of, and respond, to stimuli. Split brain patients are those who underwent surgery to sever the corpus callosum, the nerve tract connecting the two hemispheres of ... Read more »

S100B protein and autism continued

by Paul Whiteley in Questioning Answers

"Our findings showing an increase in peripheral concentrations of S100B and TNF-α provide limited support to the hypothesis about the roles of altered immune function and S100B in autism spectrum disorder (ASD)."So said the findings reported by Selin Aktan Guloksuz and colleagues [1] (open-access available here) continuing some discussions a few years back on a possible role for S100B in relation to at least some autism (see here).S100B - S100 calcium-binding protein B - is a compound invo........

When you have steady eye contact, it’s hard to think (even with  friends)!

by Rita Handrich in The Jury Room

In 2015, we wrote a one of our combination (“tidbit”) posts that included a bit of information on how extended eye contact can cause hallucinations. As it turns out, it also makes it hard to think (which seems reasonable if you are having hallucinations). The researchers we are covering today say that maintaining eye contact […]... Read more »

Want a Deep Understanding? First, Know How Little You Know

by Winston Sieck in Thinker Academy

It’s natural to feel we have a deep understanding of the world. Unfortunately, we most often don’t. On the whole, we tend to think we understand how things work in much more detail than we actually do. Scientists continue to show us just how complex the world really is. And the devices we build are […]

Distortions of Reality

by The Neurocritic in The Neurocritic





President Trump this week repeated an assertion he made shortly after his election: that millions of ballots cast illegally by undocumented immigrants cost him the popular vote. If true, this would suggest the wholesale corruption of American democracy.

Not to worry: As far as anyone knows, the president’s assertion is akin to saying that millions of unicorns also voted illegally.

"Should gluten-free foods be available on prescription?"
