A new type of neuron that might play a vital role in humans’ ability to navigate their environments, report investigators. The discovery is an important step towards understanding how the brain codes navigation behavior at larger scales and could potentially open up new treatment strategies for people with impaired topographical orientation like Alzheimer’s patients.
If the mother is stressed over a longer period of time during pregnancy, the concentration of stress hormones in amniotic fluid rises, as proven by an interdisciplinary team of researchers. Short-term stress situations, however, do not seem to have an unfavorable effect on the development of the fetus.
Psychologists have found that our bodies respond differently depending on the perspective we take when helping someone who is suffering. Stepping into the perspective of the suffering person leads to a health-threatening physiological response, while reflecting on how the suffering person might feel leads to a health-promoting response.
Two stressful work characteristics, low job control and 'job strain' -- that is, high-demand, low-control work -- have been increasing in the US since 2002. The findings may explain why declines in cardiovascular disease and related mortality have slowed.
Study characterizes, for the first time, brain differences between people with a specific genetic risk for schizophrenia and those at risk for autism, and the findings could help explain the biological underpinnings of these neuropsychiatric disorders.
The human brain functions on a delicate balance of reinforcing positive behaviors and suppressing negative ones, which takes place in the dorsal striatum, a brain region critical for goal-directed behavior and implicated in drug and alcohol addiction.
Infections, chronic high blood pressure and bleeding or clotting disorders increase the risk of pregnancy-related stroke in women with preeclampsia. Although pregnancy-related stroke is rare, women with preeclampsia are at higher risk of stroke during pregnancy and postpartum.
In a small, randomized Phase I/II clinical trial (SAT1), researchers say a 100-year-old drug called suramin, originally developed to treat African sleeping sickness, was safely administered to children with autism spectrum disorder (ASD), who subsequently displayed measurable, but transient, improvement in core symptoms of autism.
Fathers with toddler daughters are more attentive and responsive to those daughters' needs than fathers with toddler sons are to the needs of those sons, according to brain scans and recordings of the parents' daily interactions with their kids.
While firearms are present in 18 percent to 64 percent of US homes, almost 40 percent of parents erroneously believe that their children are unaware where weapons are stored, and 22 percent of parents wrongly think that their children have never handled household firearms.
At a time of change and uncertainty across the country, American adults who have been affected by change at work are more likely to report chronic work stress, less likely to trust their employer and more likely to say they plan to leave the organization within the next year compared with those who haven't been affected by organizational change, according to a survey.
Researchers analysed data of hundreds of UK children who had been born through IVF or ICSI (when the man has a low sperm count), testing the same groups of children every few years up to the age of 11. They found a positive association between artificial conception and cognitive development when a child was between the ages of three and five.
