Both hemispheres of the brain process numbers

Both hemispheres of the brain process numbers

Jena (Germany) The human brain works with division of labour. Although our thinking organ excels in displaying amazing flexibility and plasticity, typically different areas of the brain take over different tasks. While words and language are mainly being processed in the left hemisphere, the right hemisphere is responsible for numerical reasoning. According to previous findings, this division of labour originates from the fact that the first steps in the processing of letters and numbers are also located individually in the different hemispheres.

Uncorrected farsightedness linked to literacy deficits in preschoolers

Uncorrected farsightedness linked to literacy deficits in preschoolers

A study funded by the National Eye Institute (NEI), part of the National Institutes of Health, has shown that uncorrected farsightedness (hyperopia) in preschool children is associated with significantly worse performance on a test of early literacy.

New theory linking brain activity to brain shape could throw light on human consciousness

UNSW Australia scientists have shown that complex human brain activity is governed by the same simple universal rule of nature that can explain other phenomena such as the beautiful sound of a finely crafted violin or the spots on a leopard.

The UNSW team has identified a link between the distinctive patterns of brain function that occur at rest and the physical structure of people's brains.

Capitalize on 'life transitions' to instill better environmental behaviors

Interventions intended to encourage green choices among individuals, including for recycling or energy use, would be better targeted at moments of major change in people's lives if they are to stick, according to a new study from University of Bath psychology researchers.

How can peers, parents, schools and new media stop bullying?

Los Angeles, CA (January 27, 2016) A new review of research out today outlines roles and recommendations for peers, parents, schools and new media platforms to stop bullying. This review was published in Policy Insights from the Behavioral and Brain Sciences, a Federation of Associations in Behavioral & Brain Sciences (FABBS) journal published in partnership with SAGE Publishing.

1 in 10 suicide attempt risk among friends and relatives of people who die by suicide

People bereaved by the sudden death of a friend or family member are 65% more likely to attempt suicide if the deceased died by suicide than if they died by natural causes. This brings the absolute risk up to 1 in 10, reveals new UCL research funded by the Medical Research Council.

The researchers studied 3,432 UK university staff and students aged 18-40 who had been bereaved, to examine the specific impacts associated with bereavement by suicide. The results are published in BMJ Open.

Brain structure governing emotion is passed down from mother to daughter, says UCSF study

A study of 35 families led by a UC San Francisco psychiatric researcher showed for the first time that the structure of the brain circuitry known as the corticolimbic system is more likely to be passed down from mothers to daughters than from mothers to sons or from fathers to children of either gender. The corticolimbic system governs emotional regulation and processing and plays a role in mood disorders, including depression.

A master switch that plays a key role in energy metabolism and human brain evolution

Scientists have long used comparative animal studies to better understand the nuances of human evolution, from making diverse body plans to the emergence of entirely powerful and unique features structures, including the human brain.

Study details source of mental problems associated with MS

A study out today sheds new light on multiple sclerosis (MS), specifically damage in the brain caused by the disease that may explain the slow and continuous cognitive decline that many patients experience. The findings, which appear in the Journal of Neuroscience, show that the brain's immune system is responsible for disrupting communication between nerve cells, even in parts of the brain that are not normally considered to be primary targets of the disease.

Brain's wiring connected to sensory processing disorder

Researchers at UC San Francisco have found that boys and girls with sensory processing disorder (SPD) have altered pathways for brain connectivity when compared to typically developing children, and the difference predicts challenges with auditory and tactile processing.
