  • Being Refreshed Is Not The Same As Being Hydrated

    Being Refreshed Is Not The Same As Being Hydrated

    Yuki Oka, an assistant professor of biology and Chen Scholar at Caltech, wanted to better understand how the brain processes satiation and pleasure signals related to drinking. He was curious for example why, after you have exercised on a hot day, a cool glass of water will quench your thirst immediately—even before your body has […]

  • Anxious People Quicker to Flee Danger

    Anxious People Quicker to Flee Danger

    New research conducted by Dean Mobbs, assistant professor of cognitive neuroscience at Caltech shows that individuals with anxiety escape distant threats of danger sooner. The study appeared online May 20 in the journal Human Nature Behavior and was funded by the National Institute of Mental Health and the Tianqiao & Chrissy Chen Institute for Neuroscience.   Read more […]

  • How the Brain Learns New Skills

    How the Brain Learns New Skills

    Seeking to discover basic limits on the brain’s plasticity, a new Caltech study discovered that learning is indeed easier when related to skills one already has because pre-existing neuronal structure constrains what one can learn. In other words, it is likely that the skills we already have developed restrict what we can learn easily in […]

  • Hooked on Salty Foods? These Neurons are to Blame

    Hooked on Salty Foods? These Neurons are to Blame

    Potato chips, French fries, popcorn—whichever your preference, we all know that salt is a key component of many tasty foods. But eating too much salt has potential health risks and can lead to cardiovascular and cognitive disorders. Now, Caltech researchers in the lab of Yuki Oka, an assistant professor of biology and Chen Scholar, have […]

  • Blech! Brain Science Explains Why You’re Not Thirsty For Salt Water

    Blech! Brain Science Explains Why You’re Not Thirsty For Salt Water

    Chen Scholar, Yuki Oka, an assistant professor of biology at Caltech, was interviewed on NPR’s “All Things Considered” about his research into how the brain regulates sodium appetite. Oka’s team used a technique called optogenetics to switch on the neurons related to sodium appetite in mice brains. The effects were immediate.   Learn more on […]

  • Evidence for a Human Geomagnetic Sense

    Evidence for a Human Geomagnetic Sense

    Researchers at Caltech and the University of Tokyo developed a robust experiment that shows many humans are able to unconsciously detect changes in Earth-strength magnetic fields. Neuroscientist and TCCI®-affiliated faculty member, Shin Shomojo, worked with Caltech geoscientist Joseph Kirschvink and University of Tokyo neuroengineer Ayu Matani on the project.   Read more on the Caltech […]

  • This is a Neuron on Nicotine

    This is a Neuron on Nicotine

    A team of scientists has developed a protein sensor that glows in the presence of nicotine, allowing the researchers to observe nicotine’s movements in cells and reveal more about the nature of nicotine addiction. The work was led by Henry Lester, professor of biology at Caltech and an affiliated faculty member of the Tianqiao and Chrissy […]

    From Fruit Fly To Stink Eye: Searching For Anger’s Animal Root

    Hear David Anderson, Director of the Tianqiao and Chrissy Chen Institute for Neuroscience at Caltech, being interviewed on NPR’s “All Things Considered” about his research into whether animals experience anger like humans do.   Click here to listen on NPR.org

  • Autism and Theory of Mind

    Autism and Theory of Mind

    Researchers at Caltech have come up with a new way of testing one’s theory of mind which is defined as the ability to understand other people’s beliefs, preferences, and intentions as distinct from one’s own. Theory of mind is complex and involves multiple neural processes. The team, which just published their work in Current Biology, found that […]

  • A Piece of the Puzzles

    A Piece of the Puzzles

    Caroline Charpentier is a Caltech postdoc working with TCCI®-affiliated faculty member, John O’Doherty. By combining behavioral measures of observational learning with brain imaging, Charpentier is developing computational models (alogorithms) that will help us understand different types of human social behaviors such as interpreting the actions of others, decision-making or resolving uncertainties.   Read more on […]
