Human Brains Unlikely To Evolve Into A ‘Supermind’

Human minds have hit an evolutionary “sweet spot” and – unlike computers – cannot continually get smarter without trade-offs elsewhere, according to research by the University of Warwick. Researchers asked the question why we are not more intelligent than we are given the adaptive evolutionary process. Their conclusions show that you can have too much […]

The Nature Of Change In Aging And Changing Brains

As we get older, our cognitive abilities change, improving when we’re younger and declining as we age. Scientists posit a hierarchical structure within which these abilities are organized. There’s the “lowest” level — measured by specific tests, such as story memory or word memory; the second level, which groups various skills involved in a category […]

Researcher Urges Scientists To Stop Emphasizing The Shortcomings Of People With Autism

We must stop considering the different brain structure of autistic individuals to be a deficiency, as research reveals that many autistic people – not just “savants” – have qualities and abilities that may exceed those of people who do not have the condition, according to a provocative article published today in Nature by Dr. Laurent […]

Autistic Intellectual Disabilities Related To Parental Age, Education, And Ethnicity, But Not Income

New research from the University of Utah in collaboration with the Utah Department of Health (UDOH) shows that the presence or absence of intellectual disability (ID) and autism spectrum disorders (ASD) varies with risk factors such as gender, parental age, maternal ethnicity, and maternal level of education. The study, published Sept. 15, 2011, in Autism […]

New Understanding Of Brain Protein May Lead To New Therapies For Fragile X Syndrome Or Autism

Researchers now have a much clearer understanding of how mutations in a single gene can produce the complex cognitive deficits characteristic of Fragile X Syndrome, the most common inherited form of intellectual disability. As the majority of patients with Fragile X Syndrome also display autism-like symptoms, the findings offer hope for treating both conditions. The […]

25-Year Cellular Mystery Solved That Might Benefit People With Learning And Intellectual Deficits

A University of Wisconsin-Madison research team has solved a 25-year mystery that may lead to better treatments for people with learning deficits and mental retardation. Synaptophysin is the first protein and most abundant ever found on the membranes surrounding the tiny sacs that carry chemical messengers to synapses, the gaps where communication between nerve cells […]
