Phys .org: Artificial neural networks learn better when they spend time not learning at all

Phys .org: Artificial neural networks learn better when they spend time not learning at all. “Artificial neural networks leverage the architecture of the human brain to improve numerous technologies and systems, from basic science and medicine to finance and social media. In some ways, they have achieved superhuman performance, such as computational speed, but they fail in one key aspect: When artificial neural networks learn sequentially, new information overwrites previous information, a phenomenon called catastrophic forgetting.”

University of Glasgow: Researchers Propose A Roadmap To Understand Whether AI Models And The Human Brain Process Things The Same Way

University of Glasgow: Researchers Propose A Roadmap To Understand Whether AI Models And The Human Brain Process Things The Same Way. “Researchers use Deep Neural Networks, or DNNs, to model the processing of information, and to investigate how this information processing matches that of humans…. New research, published in the journal Trends in Cognitive Sciences and led by the University of Glasgow’s School of Psychology and Neuroscience, presents a new approach to understand whether the human brain and its DNN models recognise things in the same way, using similar steps of computations.”

Caltech: Caltech to Study How the Brain Responds to Virtual Environments

Caltech: Caltech to Study How the Brain Responds to Virtual Environments. “The rise of social media has meant that social and professional interactions are increasingly carried out online. This trend is expected to continue in the coming decades, as the digital world becomes more immersive and realistic. To understand how the human brain might be affected by this shift, Dean Mobbs, professor of cognitive neuroscience, is leading a new project that will use social psychology and neuroscience to explore the relationship between social media use and mental health.”

HPC Wire: Nvidia Announces Database of 100K AI and HPC-enabled Brain Images

HPC Wire: Nvidia Announces Database of 100K AI and HPC-enabled Brain Images. “Researchers at King’s College in London have curated the largest database of synthetic brain images in the world using Nvidia’s Cambridge-1 supercomputer and artificial intelligence. The database contains 100,000 images of brains and is being made freely available to healthcare researchers to advance cognitive disease research.”

KnowTechie: No, cell phones don’t give you brain tumors, study finds

KnowTechie: No, cell phones don’t give you brain tumors, study finds. “Ever since cell phones became popular decades ago, there has been concern about their effect on our bodies. Specifically, there has been a lot of speculation that cell phone radiation could increase the risk of brain tumors. However, recent findings from a long-term study indicate no relationship between cell phone use and brain cancer.”

BBC: Scans reveal how Covid may change the brain

BBC: Scans reveal how Covid may change the brain. “Catching Covid may cause changes to the brain, a study suggests. Scientists found significant differences in MRI (magnetic resonance imaging) scans before and after infection. Even after a mild infection, the overall size of the brain had shrunk slightly, with less grey matter in the parts related to smell and memory.”

University of Maryland Baltimore: Free Video Series Can Help Kids be ‘Unstuck and On Target’

University of Maryland Baltimore: Free Video Series Can Help Kids be ‘Unstuck and On Target’ . “The series of free, educational videos are designed to support parents and caregivers tackling common emotional and behavioral topics to help children to stay organized, plan and reach their goals, be flexible thinkers and help regulate their feelings. Behavioral specialists call these skills executive functioning. By following the tips and skills in the videos, parents can help their children be successful, avoid meltdowns and negativity, and develop a shared language and ways of interacting to achieve calmer, more productive days.” There are 17 videos here. Five of them are in Spanish. You can turn on captioning (the videos are on YouTube) and the ones I spot-checked looked accurate.

National Geographic: How does COVID-19 affect the brain? A troubling picture emerges.

National Geographic: How does COVID-19 affect the brain? A troubling picture emerges.. “Hannah Davis contracted COVID-19 in March 2020, the early days of the pandemic. At the time, the New Yorker was a healthy, 32-year-old freelance data scientist and artist. But unlike many people who come down with the disease, Davis’s first sign of infection wasn’t a dry cough or fever. Her first symptom was that she couldn’t read a text message from a friend. She thought she was just tired, but the fuzziness she felt didn’t go away after a full night’s sleep. More neurological issues followed.”

Baylor College of Medicine: Largest 3D mouse brain map to help understand what makes brains smarter

Baylor College of Medicine: Largest 3D mouse brain map to help understand what makes brains smarter. “Neuroscientists seeking to understand how the brain processes information along neocortical circuits, and researchers wanting to treat brain disorders where wiring or connections are altered now have a new analytical tool at their fingertips: the largest 3D wiring diagram of the mouse brain containing hundreds of thousands of cells and nearly half a billion connections.”
