LA JOLLA—Salk Associate Professor Tatyana Sharpee, a member of the Computational Neurobiology Laboratory, has been elected a 2018 Fellow of the American Physical Society (APS) for her outstanding contribution to physics. In particular, she is granted this honor for “advancing our understanding of how neurons represent sensory signals and make decisions by pioneering new methods for analyzing neural responses to natural stimuli and uncovered organizing principles for closed loop behaviors,” according to the organization.
LA JOLLA—The words “fly like an eagle” are famously part of a song, but they may also be words that make some scientists scratch their heads. Especially when it comes to soaring birds like eagles, falcons and hawks, who seem to ascend to great heights over hills, canyons and mountain tops with ease. Scientists realize that upward currents of warm air assist the birds in their flight, but they don’t know how the birds find and navigate these thermal plumes.
LA JOLLA—Every day, websites you visit and smartphone apps that you use are crunching huge sets of data to find things that resemble each other: products that are similar to your past purchases; songs that are similar to tunes you’ve liked; faces that are similar to people you’ve identified in photos. All these tasks are known as similarity searches, and the ability to perform these massive matching games well—and fast—has been an ongoing challenge for computer scientists.
LA JOLLA—Salk Associate Professor Tatyana Sharpee has been awarded a grant of approximately $950,000 over 4 years by the National Science Foundation to study how the brain processes complex sounds. This grant is part of a multi-national project together with groups in France and Israel.
LA JOLLA—Plants and brains are more alike than you might think: Salk scientists discovered that the mathematical rules governing how plants grow are similar to how brain cells sprout connections. The new work, published in Current Biology on July 6, 2017, and based on data from 3D laser scanning of plants, suggests there may be universal rules of logic governing branching growth across many biological systems.
LA JOLLA—Despite advances in neuroscience, the brain is still very much a black box—no one even knows how many different types of neurons exist. Now, a scientist from the Salk Institute has used a mathematical framework to better understand how different cell types divide work among themselves.
LA JOLLA—Although we spend a lot of our time online nowadays—streaming music and video, checking email and social media, or obsessively reading the news—few of us know about the mathematical algorithms that manage how our content is delivered. But deciding how to route information fairly and efficiently through a distributed system with no central authority was a priority for the Internet’s founders. Now, a Salk Institute discovery shows that an algorithm used for the Internet is also at work in the human brain, an insight that improves our understanding of engineered and neural networks and potentially even learning disabilities.
LA JOLLA—If two clinicians observe the same patient with blepharospasm—uncontrollable muscle contractions around the eye—they’ll often come away with two different conclusions on the severity of the patient’s symptoms. That’s because the rating scales for blepharospasm are notoriously subjective and unreliable.
LA JOLLA—Salk researchers and collaborators have achieved critical insight into the size of neural connections, putting the memory capacity of the brain far higher than common estimates. The new work also answers a longstanding question as to how the brain is so energy efficient and could help engineers build computers that are incredibly powerful but also conserve energy.
LA JOLLA–The Society for Neuroscience (SfN), an organization of nearly 40,000 scientists and clinicians, will award the Swartz Prize for Theoretical and Computational Neuroscience to Terrence Sejnowski, Salk professor and head of the Computational Neurobiology Laboratory.
LA JOLLA–Since the early 19th century, scientists have worked to unravel the mystery of olfaction, our sense of smell.
LA JOLLA–When it comes to developing efficient, robust networks, the brain may often know best.
Researchers from the Salk Institute for Biological Studies and Carnegie Mellon University have, for the first time, determined the rate at which the developing brain eliminates unneeded connections between neurons during early childhood.
LA JOLLA—The Salk Institute is pleased to welcome a new full professor and three new assistant professors, all exceptional leaders in their respective fields. The new faculty will facilitate innovative and collaborative breakthroughs in understanding human health and disease.
