Study shows how the brain’s circuitry arises spontaneously to process visual information Researchers have explained how the regularly structured topographic maps in the visual cortex of the brain could arise spontaneously to efficiently process visual information. This research provides a new framework for understanding functional architectures in the visual cortex during early developmental stages. A KAIST research team led by Professor Se-Bum Paik from the Department of Bio and Brain Engineering has demonstrated that the orthogonal organization of retinal mosaics in the periphery is mirrored onto the primary visual cortex and initiates the clustered topography of higher visual areas in the brain. ....
Caption: Our ability to highlight surprises stems from a specific interplay of brain waves that suppress processing of predicted stimuli, such as the things we always see around the office, to pave the way for heightened processing of what s new, like a gift left on the desk one morning. Previous image Next image If you open your office door one morning and there is a new package waiting on your desk, that’s what you will notice most in the otherwise unchanged room. A recent study by MIT and Boston University neuroscientists finds that the dynamic interplay of different brain wave frequencies, rather than dedicated circuitry, appears to govern the brain’s knack for highlighting what’s surprising and downplaying what’s predictable. ....
åæ é¢ï¼Chinaâa Silver Lining to the dread 2020 -Strategic and Security Review 2020/2021, Beijing (Photo by Ji Chunhong/Guangming Picture) The COVID-19 pandemic has accelerated the unprecedented centennial changes. Regional cooperation and free trade programs advanced while the game between major powers and regional conflicts go on. The previous world-old structure was gradually collapsing while the new one has not formed yet. At the end of 2020, the Strategic and Security Review 2020/2021 seminar was held in Beijing. Dozens of scholars attended. â2020 is a year that goes down in history.

We also have witnessed a significant economic downturn, the conflict between Armenia and Azerbaijan, and the rise of populism. Thus, it is very difficult to accurately interpret the world ....
