Adolescents who stopped studying math showed a reduction in a critical brain chemical for brain development. This reduction in brain chemical was found in a key brain area that supports math, memory, learning, reasoning and problem solving.
Psychotic disorders comes with a progressive decline in IQ. If current drug treatments are successful in containing psychotic symptoms, nothing can be done to prevent the deterioration of intellectual skills that leads to loss of autonomy. Researchers (UNIGE) have discovered that prescription of selective serotonin reuptake inhibitors (SSRIs) in late childhood can reduce the deterioration of intellectual abilities and have a neuroprotective effect on some of the brain regions affected by the psychotic illness.
A novel computational approach can effectively identify genes most likely linked to Autism Spectrum Disorders, as well as predict the severity of intellectual disability using only rare mutations in genes beyond those already associated with the syndrome.
In a new study, researchers have examined how "neighborhood disadvantage" and how it can affect the developing brain, including the brain's connectivity between regions. The study appears in Biological Psychiatry: Cognitive Neuroscience and Neuroimaging, published by Elsevier.
Young people need additional support and protection in the criminal justice system because they are more susceptible to pleading guilty when innocent, a new study argues.
An international team led by SPECS Lab at the Institute for Bioengineering of Catalonia (IBEC) reveals how the brain improves through self-supervised learning. Researchers also propose a novel brain-based solution to solve a fundamental challenge in artificial intelligence: how machines could learn without direct supervision. In their opinion article, scientists provide evidence for their hypothesis and new insights into the anatomy and physiology of the core memory system in the human brain: the hippocampus.
Every one of us has different taste in music. Some like rock, others like rap, classical, alternative, Israeli, international, and so on. Researchers from Tel Aviv and Ariel Universities decided to embark on a scientific assessment to determine whether there is a connection between musical taste and a person's identity. In other words, can a person be identified only by his or her music playlist? The unequivocal conclusion was yes.
Army and Arizona State University researchers identified a set of approaches to help scientists assess how well autonomous systems and humans communicate.
Intellectual disability is most often caused by changes to the genome that take place in early fetal development and are not found in the parents' DNA. This is why the risk of recurrence in the next sibling of the family is very small, as indicated by a study conducted at the University of Helsinki. Furthermore, Finns do not have a higher risk of inherited developmental disorders compared to other Europeans in spite of the isolated nature of the population.
A team led by UC Davis Health researchers tested and validated elaborated language sampling (ELS) as a reliable set of procedures for collecting, measuring and analyzing the spoken language of youth with Down syndrome in a naturalistic setting. They found that ELS can be used to detect meaningful changes in communication skills of individuals with Down syndrome.
