Has evolution given humans unique brain structures?
Humans have at least two functional networks in their cerebral cortex not found in rhesus monkeys. This means that new brain networks were likely added in the course of evolution from primate ancestor to human. These findings, based on an analysis of functional brain scans, were published in a study by neurophysiologist Wim Vanduffel (KU Leuven and Harvard Medical School) in collaboration with a team of Italian and American researchers.

Research showing why hierarchy exists will aid the development of artificial intelligence
New research explains why so many biological networks, including the human brain (a network of neurons), exhibit a hierarchical structure, and will improve attempts to create artificial intelligence. The study, published in PLOS Computational Biology, demonstrates this by showing that the evolution of hierarchy -- a simple system of ranking -- in biological networks may arise because of the costs associated with network connections.

'Connector hubs' are the champions of brain coordination
Swinging a bat at a 90-mph fastball requires keen visual, cognitive and motor skills. But how do diverse brain networks coordinate well enough to hit the ball? A new University of California, Berkeley, study suggests the human brain's aptitude and versatility can be credited in large part to 'connector hubs,' which filter and route information. (2015-11-23)

Magnetic resonance imaging deconstructs brain's complex network
A team headed by scientists at Northwestern University, using functional magnetic resonance imaging (fMRI), has shown how to visualize the human brain as a massive, interacting, complex network governed by a few underlying dynamic principles.

Neurofeedback tunes key brain networks, improving subjective well-being in PTSD
Pioneering research conducted at Western University (London, Canada) points to a promising avenue for the treatment of post-traumatic stress disorder: utilising neurofeedback training to alter the plasticity of brain networks linked to the condition. During neurofeedback, intentional control of one's own brain activity may be learned with what's called a brain-computer interface, which is able to represent graphically a person's real-time brain activation on a computer.

High and low exercise intensity found to influence brain function differently
A new study shows for the first time that low and high exercise intensities differentially influence brain function. Using resting state functional magnetic resonance imaging (Rs-fMRI), a noninvasive technique that allows for studies on brain connectivity, researchers discovered that low-intensity exercise triggers brain networks involved in cognition control and attention processing, while high-intensity exercise primarily activates networks involved in affective/emotion processing. The results appear in a special issue of Brain Plasticity devoted to Exercise and Cognition. (2020-01-30)

Human working memory is based on dynamic interaction networks in the brain
A research project of the Neuroscience Center of the University of Helsinki sheds light on the neuronal mechanisms sustaining memory traces of visual stimuli in the human brain.

Smart people have better connected brains
Differences in intelligence have so far mostly been attributed to differences in specific brain regions. However, are smart people's brains also wired differently to those of less intelligent persons? A new study published by researchers from Goethe University Frankfurt (Germany) supports this assumption. In intelligent persons, certain brain regions are more strongly involved in the flow of information between brain regions, while other brain regions are less engaged. (2017-11-22)
