Predictive Processing: the role of confidence and precision

by Sergio Graziosi in Writing my own user manual - Sergio Graziosi's Blog

This is the second post in a series inspired by Andy Clark’s book “Surfing Uncertainty“. In the previous post I’ve mentioned that an important concept in the Predictive Processing (PP) framework is the role of confidence. Confidence (in a prediction)…Read more ›... Read more »

A Survey of Our Secret Lives

by Neuroskeptic in Neuroskeptic_Discover

What kinds of secrets does the average person keep? In a new paper, Columbia University researchers Michael L. Slepian and colleagues carried out a survey of secrets.



Slepian et al. developed a 'Common Secrets Questionnaire' (CSQ) and gave it to 600 participants recruited anonymously online. Participants were asked whether they'd ever had various secrets, at any point in their lives. The results are a monument to all our sins:

It turns out that extra-relational thoughts - meaning "thou... Read more »

Gastrin-releasing peptide and autism continued

by Paul Whiteley in Questioning Answers

Yet another 'continued' or 'part 2' short post for you today, building on some previous - very preliminary research - talking about the use of gastrin-releasing peptide (GRP) and autism (see here).The authors included on the paper by Josemar Marchezan and colleagues [1] are familiar ones to this part of the autism research landscape as per the other occasions that members of this group have looked at / talked about GRP and autism in the peer-reviewed domain.GRP is all about a compound that 'does........

Characterization of a FLCN mutation associated with RCC

by Joana Guedes in BHD Research Blog

Mutations in the FLCN gene are the cause of Birt-Hogg-Dubé (BHD) syndrome, a rare disease characterized by renal cell carcinoma (RCC), pneumothorax and fibrofolliculomas. In their new study, Bartram et al. (2017) identify a heterozygous mutation in the FLCN gene in a patient with RCC. DNA from tumour and a metastasis was analysed and the authors demonstrated skipping of exon 11 as the consequence of this mutation leading to a shift in the reading frame and the insertion of a premature sto........

Injury risk and ADHD: part 2

by Paul Whiteley in Questioning Answers

Consider this short post a sort of follow-on to a previous entry on this blog concerning the elevated risk of injury following a diagnosis of attention-deficit hyperactivity disorder (ADHD). The paper in question today is that by Wu-Chien Chien and colleagues [1] who yet again [2], brought the quite significant scientific weight of the "National Health Insurance Research Database in Taiwan" to bear on this topic.In this latest paper, Chien et al relied on data from a 'subset' of the main in........

On vaccinated and un-vaccinated homeschooled children: the disappearing-reappearing-disappearing-reappearing studies

by Paul Whiteley in Questioning Answers

I originally began writing this post in the last week of November 2016 following first sight of the study abstract by Anthony Mawson and colleagues [1] and their journey into a topic that has had its fair share of discussion/argument* (*delete as appropriate) with autism in mind down the years: are vaccines or immunisation patterns potentially linked to [some] autism?As it happened, this post was shelved for some time because (a) only an abstract appeared despite a publication date accompan........

Paper About Plagiarism Contains Plagiarism

by Neuroskeptic in Neuroskeptic_Discover

Regular readers will know that I have an interest in plagiarism. Today I discovered an amusing case of plagiarism in a paper about plagiarism.

The paper is called The confounding factors leading to plagiarism in academic writing and some suggested remedies. It recently appeared in the Journal of the Pakistan Medical Association (JPMA) and it's written by two Saudi Arabia-based authors, Salman Yousuf Guraya and Shaista Salman Guraya.



Here's an example of the plagiarism: a 2015 paper by ... Read more »

Epigenetic Marks Associated to Severe Obesity

by Delphine Fradin in EpiBeat

There is growing evidence that DNA methylation might contribute to obesity. Candidate gene methylation studies in animal models and humans have demonstrated methylation changes in promoters of various genes that are implicated in obesity, appetite control and/or metabolism, insulin signaling, immunity, growth and circadian clock regulation.

Severe obesity in children is defined as greater than or equal to 99th percentile of body mass index (BMI) for age and gender or a BMI z-score ≥3.5. Po........ Read more »

Those who only kill children are neuro-psychologically different from other murderers

Of course it isn’t a surprise that they are gravely disturbed, but who knew it was neuropsychological?  This is an article from researchers at Northwestern University and looks very specifically at similarities and differences in the neuropsychological test scores of those who killed only children and those who killed some adults as well as children.

EEG abnormalities and "high functioning" autism

by Paul Whiteley in Questioning Answers

I'm not a great fan of the term 'functioning' when it comes to autism (see here) hence the quote marks around high-functioning in the title of this post. Yes, I understand the message that it's trying to convey and that we don't have viable alternatives at the moment. It just however seems a little sweeping in terms of 'generalised' describing and labelling of people...No mind. Today I'd like to bring the paper by Özdem Ertürk Çetin and colleagues [1] to your attention and the observatio........ Read more »

Fatal Attraction: Praying Mantises (A Guest Post)

by Miss Behavior in The Scorpion and the Frog

By Britta Bibbo We all know the character: an incredibly beautiful woman that seduces the rough-and-tumble action hero, only for him to later find himself chained up over a lava pit with sharks in it! …Or something like that. A “femme fatal” is the idea of a beautiful woman who leads men to their demise. None are more perfect for this role than the female praying mantis. Praying mantis females practice the art of deception through sexual cannibalism. It’s exactly how it sounds: the m........ Read more »

Comparison of alternative zebra-structure models in solar radio emission by G.P. Chernov et al.*

by CESRA in Solar Radio Science

Discussion about the nature of zebra-structure (ZS) in type IV radio bursts continues, despite the ten proposed models. First of all, this is due to the wide variety of stripes in each new phenomenon, making the explanation of all the fine details by any one mechanism becomes impossible. The most widespread explanation is the emission at different levels of double plasma resonance (DPR), sequential on the height surfaces in the magnetic [...]... Read more »

IMFAR, the autism numbers game and 12% showing 'optimal outcome'

by Paul Whiteley in Questioning Answers

A post recently published on the Spectrum website led to my blogging entry today, and the observation that: 'Alternative screen finds high autism prevalence in U.S. state'.Discussing results delivered at IMFAR 2017 the research in question was that presented by Laura Carpenter and colleagues [1] (someone with quite a track record in autism research). This was a conference presentation and seemingly not yet peer-reviewed publication, so one needs to be a little cautious about making big clai........ Read more »

Looking for Empathy in All the Wrong Places: Bizarre Cases of Factitious Disorder

by The Neurocritic in The Neurocritic

art by Zdzisław Beksiński Factitious disorder is a rare psychiatric condition where an individual deliberately induces or fabricates an ailment because of a desire to fulfill the role of a sick person. This differs from garden variety malingering, where an individual feigns illness for secondary gain (drug seeking, financial gain, avoidance of work, etc.). The primary goal in factitious disorder is to garner attention and sympathy from caregivers and medical staff.The psychiatric handbook DSM-........ Read more »
