    Brain-Machine Interface Device Predicts Internal Speech in Second Patient

    Caltech neuroscientists are making promising progress toward showing that a device known as a brain–machine interface (BMI), which they developed to implant into the brains of patients who have lost the ability to speak, could one day help all such patients communicate by simply thinking and not speaking or miming.

  • Birds Overcome Brain Damage to Sing Again

    Birds Overcome Brain Damage to Sing Again

    Every year, more than 795,000 people experience having a stroke, often resulting in brain damage that impairs their ability to speak, walk, or perform tasks. Fortunately, in many cases, these abilities can be regained through physical therapy. With practice, our brains have remarkable abilities to rewire and repair themselves after damage. Researchers in the laboratory […]

  • How Insects Control Their Wings: The Mysterious Mechanics of Insect Flight

    How Insects Control Their Wings: The Mysterious Mechanics of Insect Flight

    Many of us would love the superpower to fly, and for good reason: Flight offers a crucial evolutionary advantage. Flying enables an animal to travel large distances quickly, in search of food and new habitats, while expending far less energy than walking. Through flight, insects colonized the planet and fostered the massive diversification of flowering […]

  • Debunking a Decades-Long Misconception about the Origin of the Vertebrate Sympathetic Nervous System

    Debunking a Decades-Long Misconception about the Origin of the Vertebrate Sympathetic Nervous System

    For decades, researchers believed that lamprey—eel-like jawless fish—did not have sympathetic neurons, which are a part of the peripheral nervous system. The sympathetic nervous system is made up of nerves that target internal organs throughout the body, including the heart, pancreas, and gut. Persistent activity of the sympathetic nervous system is required to maintain homeostasis, […]

  • When Does the Brain Process Reward and Risk?

    When Does the Brain Process Reward and Risk?

    Imagine that you are considering buying stock in a company. You know what its current value is, and you suspect that you could make a healthy return on your investment. But this stock is very volatile: some days up, some days down. Yes, you could make a lot of money, but you could also lose […]

  • Mutant Newts Can Regenerate Previously Defective Limbs

    Mutant Newts Can Regenerate Previously Defective Limbs

    Many salamanders have the remarkable ability to regrow their own limbs and tails after an injury. How are they able to do this, while more complex mammals, such as humans, cannot? “Certain animals like zebrafish and salamanders are able to regenerate body parts, but higher up on the evolutionary tree of life, regeneration happens much […]

  • Large Language Models in the Classroom

    Large Language Models in the Classroom

    In fall 2023, Professor Frederick Eberhardt allowed Ethics & AI students to use large language models (LLMs) like ChatGPT in assignments, sparking debate. Eberhardt required ‘Generative AI Memos’ detailing tool use. He embraced LLMs despite initial challenges, noting students’ evolution in integrating human and AI-generated content. While some produced impressive work, others struggled with machine […]

  • On behalf of all investigators, Ying Mao presents the results of the Chinese MAGIC-MT study at the 2024 International Stroke Conference

    On behalf of all investigators, Ying Mao presents the results of the Chinese MAGIC-MT study at the 2024 International Stroke Conference

    On February 9, 2024, Ying Mao, Director of the Translational Center of Tianqiao and Chrissy Chen Institute, released the results of the MAGIC-MT study on managing non-acute subdural hematoma using liquid materials on behalf of all investigators in the closing ceremony of the 2024 International Stroke Conference in the United States. In recent years, studies […]

  • Large-scale exome-wide association analysis identifies new genes associated with sleep

    Large-scale exome-wide association analysis identifies new genes associated with sleep

    A joint team led by Jintai Yu, a researcher at Tianqiao and Chrissy Chen Institute, identified new genes associated with sleep phenotypes based on exome-wide sequencing data and association analysis algorithms of nearly 450,000 people, further analyzed the genetic contribution of rare mutations to sleep phenotypes, and explained the genetic mechanisms underlying the association of […]

  • Weight affects the risk of neurological and psychiatric disorders differently

    Weight affects the risk of neurological and psychiatric disorders differently

    A team led by Jintai Yu, a researcher at the Tianqiao and Chrissy Chen Institute, explored the correlation between body mass index (BMI) and its changes and BMI-metabolic health status with six neurological and psychiatric disorders (stroke, dementia, Parkinson’s disease, anxiety, depression, and sleep disorders). The study demonstrated the harmful effects of obesity on stroke, […]
