Correlated genotypes in friendship networks

It is well known that humans tend to associate with other humans who have similar characteristics, but it is unclear whether this tendency has consequences for the distribution of genotypes in a population. Although geneticists have shown that  populations tend to stratify genetically, this … Continue reading

Creative People Have Better Connected Brains

A new study reports highly creative people appear to have more connections between their brain hemispheres.  Highly creative people have significantly more nerve connections between the right and left hemispheres. Seemingly countless self-help books and seminars tell you to tap … Continue reading

Network Hubs in the Human Brain

Virtually all domains of cognitive function require the integration of distributed neural activity. Network analysis of human brain connectivity has consistently identified sets of regions that are critically important for enabling efficient neuronal signaling and communication. The central embedding of … Continue reading

Neural language networks at birth

The ability to learn a language is a human trait. In adults and children, brain imaging studies have shown that auditory language activates a bilateral fronto-temporal network with a left hemispheric dominance. It is an open question whether these activations … Continue reading

Dynamic reconfiguration of Human Brain Networks during Learning

Human learning is a complex phenomenon requiring flexibility to adapt existing brain function and precision in selecting new neurophysiological activities to drive desired behavior. These two attributes — flexibility and selection — must operate over multiple temporal scales as performance … Continue reading

Network structure and dynamics of the mental workspace

We do not know how the human brain mediates complex and creative behaviors such as artistic, scientific, and mathematical thought. Scholars theorize that these abilities require conscious experience as realized in a widespread neural network, or “mental workspace,” that represents … Continue reading
