People’s neural responses while watching videos predict whether they will become friends in the future, study finds

Throughout the course of their lives, people typically encounter numerous other individuals with different interests, values and backgrounds. However, not all these individuals will become their good friends, life partners, or meaningful people in their lives.

Many past psychology and behavioral science studies investigated the relationships between different people and what contributes to their perceived affinity to others. While some of these studies linked friendship to physical proximity, interpersonal similarities and other factors, the associated with between people have not yet been fully elucidated.

Researchers at University of California Los Angeles (UCLA) and Dartmouth College recently carried out a study exploring the possibility that people who end up becoming friends exhibit similar neural activity patterns. Their findings, published in Nature Human Behavior, suggest that people are in fact drawn to others who exhibit similar emotional and mental responses to their surroundings.

Your cells can hear

Kyoto, Japan — There’s a sensation that you experience — near a plane taking off or a speaker bank at a concert — from a sound so total that you feel it in your very being. When this happens, not only do your brain and ears perceive it, but your cells may also.

Activity of large-scale cortical networks follows cyclical pattern, study finds

The human brain can concurrently support a wide range of advanced mental functions, including attention, memory and the processing of sensory stimuli. While past neuroscience studies have gathered valuable insight into the neural underpinnings of each of these processes, the mechanisms that ensure that they are performed efficiently and in a timely fashion have not yet been fully elucidated.

Researchers at the University of Oxford and other institutes recently set out to explore how the activity of large-scale cortical functional networks, interconnected in the brain’s outermost layer, changes over time. Their findings, published in Nature Neuroscience, suggest that the overall order in which these networks become active follows an inherently cyclical pattern.

“This research was inspired by observations that transitions between large-scale brain networks are asymmetric: we have seen that in many cases it is much more likely that network X follows network Y than the other way around,” Dr. Mats W.J. van Es, postdoctoral researcher at the University of Oxford and first author of the paper, told Medical Xpress.
