AI Emulates Brain’s Memory Replay, Uncovering How We Learn

Scientists have made strides in uncovering the mechanisms underlying memory formation and consolidation in the brain during rest or sleep. Their research focuses on the role of the hippocampus, a brain region important for memory, and its place cells which "replay" neuronal sequences. A team of scientists built an artificial intelligence model to better understand these processes, discovering that sequences of experiences are prioritized during replay based on familiarity and rewards. The AI agent was found to learn spatial information more effectively when replaying these prioritized sequences, offering valuable insight into the way our brains learn and process information.

Novel Proteins Designed With Generative AI

Researchers developed an AI system called ProteinSGM, which uses generative diffusion to create entirely new therapeutic proteins. The model learns from image representations to generate fully new proteins that appear to be biophysically real, meaning they fold into configurations that enable them to carry out specific functions within cells. The researchers hope the system will help advance the field of generative biology, promising to speed drug development by making the design and testing of entirely new therapeutic proteins more efficient and flexible.

Machine-Learning Algorithm Predicts What Mice See From Brain Data

EPFL researchers have developed a novel machine learning algorithm called CEBRA, which can predict what mice see based on decoding their neural activity. The algorithm maps brain activity to specific frames and can predict unseen movie frames directly from brain signals alone after an initial training period. CEBRA can also be used to predict movements of the arm in primates and to reconstruct the positions of rats as they move around an arena, suggesting potential clinical applications.

Listen and Learn: AI Systems Process Speech Signals Like Human Brains

Artificial intelligence (AI) systems can process signals similar to how the brain interprets speech, potentially helping to explain how AI systems operate. Scientists used electrodes on participants' heads to measure brain waves while they listened to a single syllable and compared that brain activity to an AI system trained to learn English, finding that the shapes were remarkably similar, which could aid in the development of increasingly powerful systems.

AI-Empowered High Schoolers Discover Breakthrough Brain Tumor Treatments

Three high school students from different countries identified new therapeutic targets for glioblastoma multiforme (GBM) using artificial intelligence. The AI screened datasets from the National Center for Biotechnology Information and found new therapeutic targets implicated in treating both aging and GBM. The teens used AI to analyze the genes and identified three that were strongly correlated with both aging and glioblastoma and could serve as potential therapeutic targets for new drugs.

Cracking the Code of Sound Recognition: Machine Learning Model Reveals How Our Brains Understand Communication Sounds

Researchers developed a machine learning model that mimics how the brains of social animals distinguish between sound categories, like mating, food or danger, and react accordingly. The algorithm helps explain how our brains recognize the meaning of communication sounds, such as spoken words or animal calls, providing crucial insight into the intricacies of neuronal processing. Insights from the research pave the way for treating disorders that affect speech recognition and improving hearing aids.

Using Artificial Intelligence to Speed up Discovery of New Drugs

Experts see a bright future in the complementary use of artificial intelligence (AI) and structure-based drug discovery for drug discovery. Researchers explain how computational methods will streamline drug discovery by predicting which drug molecules are most likely to bind with the target receptor. The structure-based and AI-based approaches complement each other and can save time and money while yielding better results than traditional trial-and-error methods.

Biological Brains Outpace AI in Learning, Thanks to Structured Exploration

When it comes to rapid learning, the biological brain seems to have an edge over current AI technology. Scientists worked with different models of reinforcement learning to understand the algorithms that the brain uses to learn. They found that the directed exploration used by animals makes learning more efficient and requires less experience, unlike artificial agents that explore randomly.
