Short Sleep Duration in Children with Autism

by William Yates, M.D. in Brain Posts

Parents of children with autism and autism spectrum disorder commonly report sleep problems in their child.However, there have been few prospective systematic studies of sleep in this disorder.Joanna Humphreys from Canada and colleagues from England recently published an important manuscript addressing this topic.They used data from the Avon Longitudinal Study of Parents and Children. This data set includes prospective data collected from a cohort of over 14,000 children born between April 1991 ........ Read more »

Deleting The ‘I’ From CIAP

by Pieter Carrière in United Academics

Although similar symptoms are found in other polyneuropathies, CIAP is an exceptional disease, primarily because the cause is unknown. Researchers only recently found an interesting link between CIAP and other clinical conditions, which could lead to a better diagnosis.... Read more »

Fine-Tuning Stephen Hawking’s Theory of Mass

by Perikis Livas in Tracing Knowledge

If you want to know your body’s mass, you hop on a scale and watch the needle swing. But if you want to know the mass of a region out in space, there’s no cosmic equivalent — the best you can do is consult a geometric formula.... Read more »

How thinking in a foreign language makes you more rational in some ways but not others

by Christian Jarrett in BPS Research Digest

Back in 2012, US researchers showed that when people used their second, non-native language, they were less prone to a mental bias known as loss aversion. This bias means we're averse to the same outcome when it's framed in a way that highlights what's to be lost, as compared with when it's framed in a way that emphasises what's to be gained. For example, a vaccine is more appealing if it's stated that it will save 200,000 out of 600,000 people, far less unappealing if it's explained the vaccine........ Read more »

What is conscious intent anyway?

by Janet Kwasniak in Neuro-patch

A recent paper (citation below) reports that conscious intent precedes motor preparation activity, and not that motor preparation is well underway before consciousness registers intent. Here is Zschorlich and Köhling conclusion: “Motor intention (intention in action) describes a process of motor preparation without executing an overt movement. In our study, we explored the link between […]... Read more »

Soy infant formula and seizures in autism

by Paul Whiteley in Questioning Answers

Spring @ Wikipedia 'Association' is a word I'm sure many people with a connection to autism will have heard a lot about. Y'know gene X or compound Y is the plat du jour when it comes to autism aetiology; more often than not carrying the caveat 'requires further investigation'. As to whether such investigations are ever truly carried out would perhaps be an interesting piece of research on autism research.Today I'm talking about another association, another variable to throw into the st........

This month’s Nature methods (part 2): optogenetics

by Gal Haimovich in Green Fluorescent Blog

Optogenetic tools are light-sensitive genetically encoded proteins that, upon light activation, affect a molecular change in the cells. In the previous post I described an optogenetic system to induce transcription. However, the most common use is of channelrhodopsin (ChR) molecules, that alter … Continue reading →... Read more »

Brain Gray Matter Volumes in Primary Insomnia

by William Yates, M.D. in Brain Posts

Chronic primary insomnia is a sleep disorder characterized by delayed sleep onset, reduced total sleep duration and fatigue on morning awakening.In addition, by definition chronic primary insomnia cannot be due to a primary medical or psychiatric disorder. Some patients with chronic primary insomnia also demonstrate subjective and objective impairment in concentration and memory.Eun Yeon Joo and colleagues from South Korea recently published an analysis of brain structural features in 27 su........

One Meditation Session to Let the Past Go

by Katharine Blackwell in Contemplating Cognition

The sunk-cost bias is the idea that once we’ve invested in something, it’s hard to pull out of it; that would make everything we’ve invested already just a waste of time and money. The impact ranges from finishing dessert, to sticking with bad stock investments, to staying in romantic relationships long past when they’re enjoyable because of the years you’ve already given to that partner.

And the sunk cost bias may be overcome with a single 15-minute session of m........ Read more »

Vast Gene-Expression Map Yields Neurological and Environmental Stress Insights

by Perikis Livas in Tracing Knowledge

A consortium led by scientists from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) has conducted the largest survey yet of how information encoded in an animal genome is processed in different organs, stages of development, and environmental conditions. Their findings paint a new picture of how genes function in the nervous system and in response to environmental stress.

They report their research this week in the Advance Online Publication of the j........ Read more »

Gamers find it easier to relax and detach from work

by Alex Fradera in BPS Occupational Digest

A new study suggests digital gaming during leisure time is associated with better recovery from working stresses, particularly when that gaming involves online interaction with other people. Contrary to prior research, time spent gaming is not an influential factor upon the findings. This suggests that rather than game play steadily replenishing personal resources, the act – or mere availability – of gaming can be beneficial in a range of forms, from a quick zap to longer immersive sessions.........

GitHub Education Officially Providing Students and Educators Free Resources

by Geoffrey Hannigan in Prophage

In my last post I talked about PLOS's efforts to improve data sharing, and how important it is to make your data and analyses tools available when you publish, especially in microbiome research. This importance of sharing published data and analysis scripts was also highlighted in a recent article in the journal Microbiome (see reference below). Now the code versioning and sharing software site GitHub is even getting on board by officially supporting students and classrooms with free micr........ Read more »

The amazing durability of infant memory: Three-year-olds show recognition of a person they met once at age one

by Christian Jarrett in BPS Research Digest

The fate of our earliest memories is something of an enigma. As adults, most of us are unable to recall memories from before we were age three or four. And yet, as toddlers we are perfectly capable of storing and recalling memories from before that age. To solve this mystery, we need to understand more about how infant memory works. Now a clever study has provided a test of just how durable infant memories can be. Osman Kingo and his colleagues in Denmark have demonstrated that three-year-olds d........ Read more »
