A very quick post today to direct you to the paper by Amy Hewitt and colleagues  who seem to have finally published their findings on autism prevalence in the Somali population in Minneapolis in the peer-reviewed domain. I had previously covered their report on this blog (see here) and the suggestion that: "Somali (1 in 32) and White (1 in 36) children were about equally likely to be identified with ASD [autism spectrum disorder], but more likely to be identified with ASD than Black and ........

"The results of this trial indicate that NAC [N-acetylcysteine] treatment was well tolerated, had the expected effect of boosting GSH [glutathione] production, but had no significant impact on social impairment in youth with ASD [autism spectrum disorder]."So said the results reported by Logan Wink and colleagues  (open-access) who, continuing an autism research theme, looked at whether this important L-cysteine prodrug might have more to give when it comes to a........

Dogs originally bought from pet stores are more likely to be aggressive to their owner compared to those from responsible breeders, even after owner-related factors are taken into account.Research by Frank McMillan et al (2013) found that dogs obtained as puppies from pet stores are more likely to have a whole range of behaviour problems than those from responsible breeders, including 3x more likely to be aggressive towards their owner. Pet store puppies come from commercial breeding establishme........ Read more »

When you hear the word “apple”, do you picture a Red Delicious apple or a green Granny Smith? Or neither, because you can't conjure up a visual image of an apple (or of anything else, for that matter)? Aphantasia is the inability to generate visual images, which can be a congenital condition or acquired after brain injury (Farah, 1984). The most striking aspect of this variation in mental life is that those of us with imagery assume that everyone else has it, while those without are flabberg........ Read more »
It's becoming easier than ever to research the genetic roots of different ethnic groups and these findings can be framed differently to either emphasise that groups are similar or different. For example, a BBC headline from 2000 stated "Jews and Arabs are 'genetic brothers'" while a 2013 Medical Daily headline claimed "Genes of most Ashkenazi Jews trace back to indigenous Europe, not Middle East". As political leaders have started citing this kind of evidence to promote their particular agenda, ........ Read more »

Can I just get it out of the way? May the 4th be with you.OK. The results from Mark Strom & Jonathan Silverberg  caught my eye recently and further evidence of a 'correlation' between asthma and developmental and/or behavioural outcomes. This time around it was "caregiver-reported speech disorders in US children" and how the appearance of asthma, hay fever and/or food allergy might show some important relationships with something like speech disorder. This follows other, similar work from........ Read more »

We usually think of laughter as a sound of joy and mirth, but in certain contexts, such as when it accompanies an insult, it takes on a negative meaning, signaling contempt and derision, especially in a group situation. Most of us probably know from experience that this makes insults sting more, now a study in Social Neuroscience has shown the neural correlates of this effect. Within a fraction of a second, the presence of a laughing crowd changes the way that the brain processes an insult.Marte........ Read more »

Machine learning, when machines, er.. learn, is of growing interest to the autism research field. The names Wall and Duda have filled quite a few posts on this blog (see here and see here for example) on this topic and their suggesting that applying machine learning algorithms to something like autism screening and detection could cut down on time taken and resources used.As per the publication of the paper by Daniel Bone and colleagues  it appears that others working in autism research are a........

Vaccines don't cause autism, but because the brain is so complex, we still don't know how much of it works so figuring out the real causes (as in more than one) of autism has been slow going. Well, researchers have identified a brain receptor that appears to initiate adolescent synaptic pruning, a process believed necessary for learning, but in this case it is one that appears to go awry in both autism and schizophrenia....

Most people who know a little bit about chronic fatigue syndrome / myalgic encephalomyelitis (CFS/ME) will probably understand the potential importance of the findings reported by Leonard Jason and colleagues  (open-access available here). Suggesting that there may be "four groupings of patients" when it comes to how we "name and define the illnesses", this research group who surveyed over 500 people "in the United States, Great Britain, and Norway" report on one of the biggest challenge........

Generally seen as antithetical to one another, evolution and religion can hardly fit in a scientific discourse simultaneously. However, in a new article, a biology researcher delves into observations on the influences a few major religions have had on evolutionists and their scientific thinking over the centuries.

Working to orient oneself to the symmetries available in mathematical situations seems like one appropriate remedy to what I've called "left-to-rightism," or "cinemathematics"—a syndrome that makes us teach concepts like the equals sign (unwittingly) in a left-to-right way, such that students take away (unwittingly) the misconception that the equals sign indicates that some answer is to follow, rather than that two expressions are equal. Some recent research points........ Read more »

Insomnia, fun fact those of us who have served or are serving in the military have a much higher incidence of sleep problems. So if you are like me and have ever been prescribed something to help you sleep, you know that there are some unwanted side effects. For instance the time I lost memory of a whole day of interacting with people to the ambien I had taken the night before, not fun. Thankfully Danish researchers found that the level of salts in the brain plays a critical role in whether we a........ Read more »

In a new Nature paper, Berkely neuroscientists Alexander G. Huth and colleagues present a 'semantic atlas' of the human brain. Huth et al. have mapped which brain areas respond to words, according to the semantics (meanings) of each word. It turns out that these maps are highly similar across individuals - which could have implications for 'mind reading' technology.
Huth et al. recorded brain activity with fMRI while seven volunteers listened to over two hours of audio narrative (taken fr... Read more »

Whilst the package inserts of the various drugs that modern medicine has at its disposal provides important information on potential mode of action, there is a growing realisation that drugs generally have quite a few more molecular targets than are perhaps listed. Take for example the quite commonly used (in some parts of the world anyway) compound called melatonin that in some instances can provide almost miraculous relief when it comes to sleeping issues under certain circumstances.

The whole of human intelligence, right at your fingertips. Sure it might not make the layman an engineer or physicist, but if we want to learn about a particular topic the internet can give us that information. But you better hold on tight before you lose it. New research finds retweeting or otherwise sharing information creates a “cognitive overload” that interferes with learning and retaining what you’ve just seen.

Is spending time looking back on our lives good for our mental health? A lot of research suggests it is, but these studies have been cross-sectional, making it hard to form a clear causal story – for example, perhaps being happier makes it more likely that people will reminisce. On the other hand, there are therapeutic trials that show purposeful reminiscence can bring about clinically meaningful decreases in depression. Now, a longitudinal investigation in Applied Cognitive Psychology provide........ Read more »
