With the advent of magnetic resonance imaging, or MRI, we have begun to appreciate how the brain continues to develop structurally through adolescence and on into adulthood. High emotionality is a characteristic of adolescents and researchers are trying to understand how ‘emotional areas’ of the brain differ between adults and adolescents.
Scientists from the National Institute of Mental Health, publishing in the November 15th issue of Elsevier’s Biological Psychiatry, have helped to advance our understanding. They studied the amygdala, the major emotional center in the brain, which undergoes structural reorganization during adolescence. To do so, they examined emotional learning in both juvenile and adult mice.
“Our work on the amygdala revealed that the neuronal pathways that carry sensory information to the amygdala directly, bypassing cortex, are more plastic in the juvenile than in adult mice,” explained senior author Alexei Morozov, PhD.
John Krystal, MD, the Editor of Biological Psychiatry, further commented on this work: “Pan and colleagues elegantly describe one developmental ‘switch’ in the regulation of the amygdala. This switch may be one way that the cortex emerges during development as having a greater role in regulating the amygdala and thus, emotional behavior.”
Dr. Morozov concluded that “this finding suggests that emotional behaviors in adolescence are less precise and more irrational because they are driven more by subcortical than by cortical structures.”Notes to Editors:

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.
Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...
A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
