Where is the suprachiasmatic nucleus?
the suprachiasmatic nucleus is represented by a small green area within the hypothalamus (indicated by red arrow).
The suprachiasmatic nuclei are two small, paired nuclei that are found in the hypothalamus. Each suprachiasmatic nucleus only contains approximately 10,000 neurons. The nuclei rest on each side of the third ventricle, just above the optic chiasm. The location provides the rationale for........ Read more »

I'm not gonna dwell too much on the findings reported by Lee and colleagues  talking about how "toddlers who suffer from AD [atopic dermatitis] at the age younger than 3 years are at a higher risk of developing ADHD [attention-deficit hyperactivity disorder] and ASD [autism spectrum disorder] during later childhood" because science already seems to understand that there may be an important connection between early allergic disease and later offspring behavioural/........

'Thick and fast' is probably the best way that I can describe the flurry of peer-reviewed scientific papers recently appearing (see here and see here for examples) talking about how chronic fatigue syndrome (CFS) (also linked to the diagnosis of myalgic encephalomyelitis, ME) might have some important biological processes attached to it.Now we can add the findings reported by Federica Ciregia and colleagues  (open-access) to the list and their observations that "the identification of bio........

"Social priming" has been the punching-bag of psychology for the past few years.
The term "social priming" refers to the idea that subtle cues can exert large, unconscious influences on human behaviour. The classic example of a social priming effect was the "professor priming" study in which volunteers who completed a task in which they had to describe a typical professor, subsequently performed better on a general knowledge task. In other words, as the authors put it, "priming a stereotype o... Read more »
Today I'm once again blogging about peer-reviewed research suggesting that when it comes to the long-term effects of attention-deficit/hyperactivity disorder (ADHD) on a person, there is some pretty solid evidence that addressing symptoms early could "potentially avert a wide range of future adverse outcomes."The paper making such a conclusion is the one from Holly Erskine and colleagues  who conducted a systematic review and meta-analysis pertinent to this topic; also taking into accoun........

A new study finds that training shelter cats leads to more contentment and better health.The study, by Nadine Gourkow and Clive Phillips (University of Queensland), tested the effects of training sessions on cats that were frustrated when they arrived at an animal shelter. The cats in the training group became more content and were healthier compared to the cats who just experienced normal shelter conditions.Prof. Clive Phillips says,“Confining a cat into a small cage after it has been roaming........

"At 13 years, adolescents who had received a diagnosis of chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME) who were attending specialist CFS/ME services were more than two times more likely to be obese than adolescents in the general population."At first reading, I wasn't particularly surprised by the findings reported by Norris and colleagues  (open-access) drawing on data partly derived from everyone's favourite UK longitudinal birth cohort: ALSPAC (Avon Longitudinal Study of Par........

Having recently mentioned the BBC headline that makes up the title of this entry in a related post (see here) I'm pleased to be finally able to bring the paper by Daniel Mackay and colleagues  (open-access) to your attention.Observing that in Scotland at least, "that season of conception is strikingly associated with the subsequent risk of special educational needs in the offspring" there are various potential implications to come from such data covering both learning (intellectual) disabilit........

Using online social media does not lead to long-term problems with our ability to concentrate, according to new research. We are social animals, so it is really no surprise that billions of us now use online tools to communicate, educate and inform each other. The advent of social media and social networking has nevertheless been phenomenally rapid.

"Hypertension in pregnancy was associated with ASD [autism spectrum disorder] in this population even after controlling for known confounders."So said the findings reported by Eileen Curran and colleagues  who, once again (see here), relied on "data from the Millennium Cohort Study" to produce some potentially important information about how adverse pregnancy conditions may/may not impact on offspring behaviour and development.Hypertension (a.k.a high blood pressure) during pre........

In answer to the question that titles this post on whether parental age differences at offspring conception might matter when it comes to offspring risk of autism or schizophrenia, the answer is very possibly. As the paper by Byars & Boomsma  (open-access) reports: "Our study shows that autistic and schizophrenic disorder risks tend to be higher, in more dissimilarly aged parents, relative to parents with the most similar ages." This age disparity issue has been mentioned previously in th........ Read more »

There are many reports of drug use leading to mental health problems, and we all know of someone having a few too many drinks to cope with a bad day. Many people who are diagnosed with a mental health disorder indulge in drugs, and vice versa. As severity of both increase, problems arise and they become more difficult to treat. But why substance involvement and psychiatric disorders often co-occur is not well understood.

"Biomarker studies of PUFA [polyunsaturated fatty acid] and treatment studies of n-3 [omega-3] PUFA in bipolar disorder show promise for indicating a way forward in the study of PUFA in bipolar disorder."I don't want to labour any points raised by the review of studies published by Erika Saunders and colleagues  looking at fatty acids and bipolar disorder but there does seem to be a familiar ring to the current evidence base on how for at least 'some' cases of bipolar diso........

Scientists have discovered a new pathway in the brain that can be manipulated to alleviate depression. The pathway offers a promising new target for developing a drug that could be effective in individuals for whom other antidepressants have failed. New antidepressant options are important because a significant number of patients don't adequately improve with currently available antidepressant drugs.

Can we and should we formally 'teach' humour to people diagnosed on the autism spectrum? Indeed, do we actually need to?Yes said the results of the study published by Ching-Lin Wu and colleagues  although I personally am not so impressed.Discussing how their results "supported the effectiveness of the 15-hour training" regime, Wu et al report that for a small group of adolescents diagnosed with an autism spectrum disorder (ASD) "and average intelligence" moves to implement "a humor-knowl........
