How evolution shapes ecological networks among species

The natural world is filled with networks. Predator and prey, flower and pollinator—each interacting pair forms a link in a networked community of organisms. Now, a French research team has developed a model that explores how evolution may help shape … Continue reading

Cross-network interactions in social cognition

Theory of Mind, empathy, and action observation are central themes in social neuroscience research. Meta-analyses of functional neuroimaging studies show substantial heterogeneity in brain activation for these cognitive abilities, depending on the type of experimental task used. We followed up … Continue reading

Network neuroscience

Despite substantial recent progress, our understanding of the principles and mechanisms underlying complex brain function and cognition remains incomplete. Network neuroscience proposes to tackle these enduring challenges. Approaching brain structure and function from an explicitly integrative perspective, network neuroscience pursues … Continue reading

Generative Models for Network Neuroscience

Network neuroscience is the emerging discipline concerned with investigating the complex patterns of interconnections found in neural systems, and to identify principles with which to understand them. Within this discipline, one particularly powerful approach is network generative modeling, in which … Continue reading

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

Brain Networks and Cognitive Architectures

Most accounts of human cognitive architectures have focused on computational accounts of cognition while making little contact with the study of anatomical structures and physiological processes. A renewed convergence between neurobiology and cognition is well under way. A promising area … Continue reading

A Survey on Bio-inspired Networking

The developments in the communication and networking technologies have yielded many existing and envisioned information network architectures such as cognitive radio networks, sensor and actor networks, quantum communication networks, terrestrial next generation Internet, and InterPlaNetary Internet. However, there exist many … 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
