A regular theme here at Neuroskeptic is the worrying issue of head movement during brain scans. We've seen that motion can alter measures of functional and structural connectivity, and that common approaches to dealing with this problem may be inadequate.
Now a new study reveals that even measures of the gross structure of the brain can be biased by excessive motion: Head motion during MRI acquisition reduces gray matter volume and thickness estimates.

Did you know that fruit flies sleep? There are actually a lot of similarities between sleep in fruit flies and sleep in humans and other mammals. For example… Image modified from Colwell, 2007 Like us, fruit flies get most of their sleep at night, and they also have an afternoon slump (although unlike us, they […]... Read more »

Otters don’t tend to be very visible to us, but they are more abundant than we might perceive them to be. Otters mostly live in isolation of one another, yet they manage to remotely communicate to one another without the aid of modern technology that we so often depend upon for communication.
On this blog, I previously wrote how otters communicate with one another using their spraints (faeces). They use them to mark their territory and to leave messages for other otters. As part of the rese........ Read more »

While the anti-vaccine movement enjoys the simple (and very wrong) answer to the cause of autism, there are people who want the actual truth. This drive had lead to a slew of causes (and risk factors) for autism in recent times. Now scientists have found that very small segments of genes called “microexons” influence how proteins interact with each other in the nervous system. In turn, this opens up a new line of research into the cause of autism.... Read more »

Increased sea temperature due to climate change can influence the distribution, abundance and seasonal timing of zooplankton. Changing zooplankton dynamics might in turn impact the higher trophic levels, such as fish and seabirds, feeding on these animals. In a recent paper, we show that temperature variation in the Atlantic waters of the Norwegian Sea and Barents Sea might have stronger effects on the abundance of the younger than older development stages of Calanus fin........

Metabolic syndrome is linked with an increased frequency and severity of lower urinary tract symptoms, but weight loss surgery may lessen these symptoms. The findings, which come from two studies published in BJU International, indicate that urinary problems may be added to the list of issues that can improve with efforts that address altered metabolism.
Lower urinary tract symptoms related to urinary frequency and urgency, bladder leakage, the need to urinate at night, and incomplete bladder........ Read more »

Despite what you may think, the supposed “explosion” of children diagnosed with autism can directly attributed to better diagnosing techniques and — more importantly — the change of definition to make Autism spectrum disorders more broad. Thankfully more causes of autism have been found, none of them remotely related to vaccines and now scientists have found that chemical modifications to DNA’s packaging—known as epigenetic changes—can activate or repress genes involved in autism s........
