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. Read More
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. Read More

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. Read More
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. Read More
Researchers report testing both the cognitive and olfactory abilities in people could help identify those at risk for developing Alzheimer's disease. Read More
The release and uptake of dopamine and serotonin becomes sluggish in rat brains following chemotherapy, researchers report. Read More
According to researchers, our brains have different traits that affect both anatomical and cognitive factors. Read More
A new study provides greater understanding of how genes influence brain structures, cognitive abilities and how neural circuits produce language. Read More
