The development of the cerebellar circuitry is driven by epigenetic “music”

by Dr. Jekyll in Lunatic Laboratories

From before birth through childhood, connections form between neurons in the brain, ultimately making us who we are. So far, scientists have gained a relatively good understanding of how neural circuits become established, but they know less about the genetic control at play during this crucial developmental process. Now, a team of researchers has described for the first time the so-called epigenetic mechanisms underlying the development of the cerebellum, the portion of the brain that allows us........

Have a sweet tooth? It may be your livers fault

by Dr. Jekyll in Lunatic Laboratories

We all love our sugar, especially during the holidays. Cookies, cake, and candy are simply irresistible. While sugar cravings are common, the physiological mechanisms that trigger our “sweet tooth” are not well defined.... Read more »

Here’s an updated version of the meteorologists ‘Santa Tracker’

by Doug Keene in The Jury Room

We’re taking a break until 2016 so we’ll see you in January! Most of us grew up watching the weather report on TV and seeing a NORAD ‘Santa Tracker’ showing where Santa and his sleigh were on their way for a long night of work. But this is 2015 and if you celebrate the holiday, […]

Early intervention before autism diagnosis

by Paul Whiteley in Questioning Answers

Santa is approaching so I don't want to keep you too long today. I just thought you might want to briefly cast your eye over the paper by Sonia Monteiro and colleagues [1] and their findings that: "most children are receiving early intervention services before their diagnostic ASD [autism spectrum disorder] evaluations, particularly if an ASD diagnosis is confirmed."Set within the context of some rather disturbing reports about children (and adults) sometimes waiting a very, very long ........

Lack of serotonin alters development and function in the brain

by Dr. Jekyll in Lunatic Laboratories

Researchers at Case Western Reserve University School of Medicine have created the first complete model to describe the role that serotonin plays in brain development and structure. Serotonin, also called 5-hydroxytryptamine [5-HT], is an important neuromodulator of brain development and the structure and function of neuronal (nerve cell) circuits.... Read more »

Reducing racial prejudice in just seven minutes 

by Doug Keene in The Jury Room

This is a very different strategy for quickly reducing racial prejudice than past research has examined. This one involves the Buddhist practice called a Loving-kindness meditation (LKM) which involves focusing on a specific individual and repeating phrases like “may you be happy and healthy”. Researchers wanted to see if practicing a Loving-kindness meditation (LKM) would […]

Here's what we get completely wrong when we're judging the difficulty of anagrams

by BPS Research Digest in BPS Research Digest

We think pronounceable anagrams are easier, but they're harderWhen you're trying to solve an anagram (that is, re-arranging a jumble of letters to form a word), sometimes the string of letters looks like complete gobbledygook and impossible to solve, but other times, the anagram is pronounceable, or parts of it are, and the challenge appears a good deal easier.Now a new article in the journal Cognition shows this intuitive assessment, though shared by most people, is completely wrong. We th........ Read more »

Prevalence of schizophrenia in China up: was Dohan (partially) right?

by Paul Whiteley in Questioning Answers

"The prevalence of schizophrenia in China has more than doubled between 1990 and 2010, with rates being particularly high in the most developed areas of modern China."So said the study results from Chan and colleagues [1] reviewing the collected peer-reviewed "epidemiological studies of schizophrenia in mainland China published between 1990 and 2010."Taking into account data from 42 eligible trials covering some "2 284 957 persons, with 10 506 diagnosed with schizophrenia" researchers appl........

Are you a ‘harbinger of failure’?

by Dr. Jekyll in Lunatic Laboratories

Diet Crystal Pepsi. Frito Lay Lemonade. Watermelon-flavored Oreos. Through the years, the shelves of stores have been filled with products that turned out to be flops, failures, duds, and losers. But only briefly filled with them, of course, because products like these tend to get yanked from stores quickly, leaving most consumers to wonder: Who exactly buys these things, anyway?...

Graphic image can be a better strategy to quit smoking

by Usman Paracha in SayPeople

Main Point:

Cigarette packs with disturbing photos are more helpful in increasing negative feelings about cigarette smoking.

Published in:

PLOS ONE

Study Further:

In a recent study, researchers from the Ohio State University worked on the placement of graphic (disturbing) images on cigarette warning labels. They were trying to compare the text-only warnings with that of graphic warning images.

Researchers worked on cigarette smokers, who were habitual of smoking 5 to 40 cigaret........ Read more »

Swearing patients take a toll on healthcare workers

by BPS Research Digest in BPS Research Digest

Although many medical terms are long and difficult to pronounce, medical settings are punctuated with words familiar to most of us – being sworn at is an occupational hazard for healthcare workers. Exactly how often does it happen? A new review published in Aggression and Violent Behaviour by Teresa Stone and colleagues finds one study suggests rates as high as three incidents per shift in a mental health setting; in other contexts the rates appear lower, but even a lower estimate suggests one........

Allergy symptoms affecting autistic symptoms?

by Paul Whiteley in Questioning Answers

I have quite a bit of time for Harumi Jyonouchi on this blog (see here and see here for example). Not only has Dr Jyonouchi got an eye for some potentially important biological issues associated with at least some cases of autism, she also seems to recognise that behavioural symptoms often seem to go hand-in-hand with other more somatic features as per her work taking gastrointestinal (GI) symptoms into account for example [1].Another, more recent paper from Dr Jyonouchi caught my eye [2], ........

Intelligence, it’s in your genes… and we can change that.

by Dr. Jekyll in Lunatic Laboratories

Ever feel like everyone around you has their brain running much faster than your own? Well, the good news is that it may not be you, it may be your genes. The other good news, we might be able to change that. Scientists from Imperial College London have identified for the first time two clusters of genes linked to human intelligence. Called M1 and M3, these so-called gene networks appear to influence cognitive function - which includes memory, attention, processing speed and reasoning.... Read more »

Tattoos as a restorative act (for college-aged women anyway) 

by Rita Handrich in The Jury Room

We write a lot about tattoos here—perhaps because we have Millennial aged kids and at least half of them have tattoos.  Okay, more than half. The meaning of tattoos has changed over the years and there seems little stigma still associated with them any longer. The authors of new research on college students (2,394 of […]

What kinds of actions do people think of as most stupid?

by BPS Research Digest in BPS Research Digest

To avoid people thinking you're stupid, above all you need to refrain from undertaking risky tasks for which you lack suitable knowledge or skills. That's according to new research published in the journal Intelligence, which is the first to systematically investigate the kinds of behaviours that people consider to be stupid or foolish. Balazs Aczel and his colleagues collected online news stories that contained descriptions of stupid behaviour, for example from the New York Times, the BBC and t........ Read more »

GABA, autism, and the correlation that wasn’t there

by Jon Brock in DrBrocktagon

Gamma aminobutyric acid (or GABA for short) is an inhibitory neurotransmitter – it makes a neuron less likely to fire. GABA is important, not only in damping down brain activity, but also in controlling the precise timing of the neural impulses. It allows groups of neurons to synchronize their activity and transmit signals across the brain. […]... Read more »

Maternal pregnancy CRP levels and offspring autistic traits

by Paul Whiteley in Questioning Answers

Elevated levels of inflammatory markers present during pregnancy have been linked to quite a few labels and diagnoses down the years. Schizophrenia is a prime example as per various peer-reviewed science with that label in mind (see here). There is still quite a bit more research to do in these days of plural schizophrenias (see here) but the intersection between immune function and psychiatry is a growing area of interest.Autism is another label that has been talked about with elevated gestatio........

Women, do you want to be a leader at a teaching hospital? Grow a mustache!

by Dr. Jekyll in Lunatic Laboratories

Thirteen percent of department leader positions at top academic medical institutions in the United States are held by women, while nearly 20 percent are held by men with mustaches. The findings of the tongue-in-cheek study, an analysis of more than 1,000 headshots of department leaders at top National Institutes of Health-funded academic medical institutions, provide a new context for examining gender disparities in the field....

The ties that bind? Comorbidity and autism (again)

by Paul Whiteley in Questioning Answers

"It was found that 92.9% of participants presented with a family history of autoimmune disease."That was one of the headline findings reported in the paper by Arlene Mannion & Geraldine Leader [1] who conducted a follow-up study to previous work [2] looking at the important issue of comorbidity and autism with a specific focus on whether "comorbid symptoms changed over time."Fifty-six children and adolescents diagnosed with DSM-IV autism spectrum disorder (ASD) participated in their study, d........
