Where are the mammillary bodies?
The mammillary bodies are part of the diencephalon, which is a collection of structures found between the brainstem and cerebrum. The diencephalon includes the hypothalamus, and the mammillary bodies are found on the inferior surface of the hypothalamus (the side of the hypothalamus that is closer to the brainstem). The mam........ Read more »
"This large study showed a prospective association of infant muscle tone with autistic traits in childhood."So said the findings reported by Fadila Serdarevic and colleagues  who, looking at nearly 3000 children, were able to assess early motor development and muscle tone "between ages 2 and 5 months" and later parental ratings of autistic traits in children at 6 years of age. Said autistic traits were surveyed using the "the Social Responsiveness Scale (SRS) and the Pervasive Developmental P........ Read more »

Although primarily looking at the potential predictors of language outcome, the study results published by Cristina McKean and colleagues  revealed the rather important title heading this blog entry: "Almost 19% of children (22/1204;18.9%) met criteria for low language at 7 years."The source of the finding was a cohort of some 1900 infants "recruited at age 8 to 10 months" who were followed until aged 7 years old and subject to quite a bit of research inspection looking at "early life factors........

Knowing a breed of dog may have health problems does not stop people from wanting one, because emotions get in the way. A new Danish study by Peter S Sandøe (University of Copenhagen) et al investigates the reasons why people acquire particular small breeds of dog and how attached the owners feel to their pet. The research helps explain why some breeds are popular despite a high incidence of welfare problems. The study looked at people in Denmark with French Bulldogs, Chihuahuas, Cava........ Read more »

"At 9 months of age, infants developing ASD [autism spectrum disorder] were more likely to fail to orient to their names, persisting through 24 months."So said the findings reported by Meghan Miller and colleagues  investigating an often over-looked but typically informative question relevant to childhood autism screening and assessment: the response to name.

New research casts doubt on an old explanation for the play bow – and suggests it’s all about more play.The play bow is a glorious signal in dogs. The bum goes up and the elbows go down, leaving the rear end sticking up, usually accompanied by a lovely happy face (as pictured above). Not just reserved for other dogs, our canine friends will play bow to us too.Traditionally, it was believed that the play bow serves as a signal to say something like, “I’m just playing, it’s not real!”,........

When the psychiatrist Hermann Rorschach blotted ink onto paper to produce a series of abstract patterns, could he have known that nearly 100 years later, the Rorschach test would be a household name?
Although the use of the Rorschach to diagnose mental illness is mostly a thing of the past, research on the test continues. Last week, two new papers were published on the Rorschach blots, including a fractal analysis of the images themselves and a brain scanning study using fMRI.

"Catatonic symptoms are more prevalent in young people with autism than previously thought" said the article recently published by Breen and Hare . Continuing a research theme of at least one of the authors , the idea that catatonic symptoms - primarily manifesting as stupor, unresponsiveness to light, noise or touch, mutism, etc - might be over-represented when it comes to autism is not a new one by any means.Breen & Hare set about looking for "the presence and nature of such att........

Psychology experiments are not generally fodder for this blog when it comes to autism. The main reason being that quite a few appearing in the peer-reviewed literature tend to look at quite abstract features perhaps somewhat removed from the daily lives of autistic people and their significant others. A few also seem to struggle with the idea that grand over-arching psychological theories (that seem to inevitably follow psychological findings in particular) are not required when it comes to auti........

The paper by Charlotte Willfors and colleagues  (open-access) provides some food for thought today and the observation that various individual and cumulative medical events - "early medical events likely to be caused by environmental factors" - may be important to at least some autism.Researchers "scrutinized the early medical histories of a rare and informative sample of 13 MZ [monozygotic] twin pairs discordant for clinical ASD [autism spectrum disorder]" also including "13 M........

Dominance is an outdated approach to dog training – and it also means dogs miss out on fun.Approaches to dog training based on dominance rely on the idea that you have to be the ‘alpha’ or pack leader. Unfortunately, this type of dog training is not just out-of-date and potentially risky, but modern approaches to dog training are also a lot more fun – for you and the dog.What is dominance in dog training?We sometimes hear the phrase ‘my dog is being dominant.’ ‘Your dog is being do........
