Researchers have identified a neural mechanism that supports advanced cognitive functions such as planning and problem-solving. The mechanism distributes information from a single neuron to larger neural populations in the prefrontal cortex.
Researchers say the COVID pandemic has had an impact on people's cognitive abilities and risk perception.
Higher intelligence was associated with higher temporal stability of brain network modularity. Brain regions of the dorsal attention network contributed most to the observed effect.
Grandiose narcissists are significantly less likely to use critical thinking when it comes to important problem solving or decision making. While narcissists perceive themselves to be above average intelligence and strong critical thinkers, they are unable to use reflective thinking skills effectively. The high levels of confidence they have in their intellectual abilities are often misplaced.
Higher levels of lead in topsoil have been linked to an increased risk of cognitive impairments, learning difficulties, and problems with decision making in 5-year-old boys.
According to researchers, there is an optimum amount of dopamine that should be present within the brain. This optimum amount can help improve cognitive performance on tasks, researchers report.
A new study reports female guppies with smaller brain mass can distinguish between attractive males, but do not find them more appealing or choose to mate with them over less attractive guppies. Researchers say the study sheds new light of the link between mate preference and cognitive ability.
Researchers have identified a link between cortical surface area, height and cognitive ability. The study reports taller people have bigger cortices, which in turn is linked to better cognitive function.
Researchers report testing both the cognitive and olfactory abilities in people could help identify those at risk for developing Alzheimer's disease.
The release and uptake of dopamine and serotonin becomes sluggish in rat brains following chemotherapy, researchers report.
According to researchers, our brains have different traits that affect both anatomical and cognitive factors.
A new study provides greater understanding of how genes influence brain structures, cognitive abilities and how neural circuits produce language.
