  • Memory and Navigation with John Kubie: The NYC Perspective on Hippocampal History
    Jul 9 2024

    The beginnings of neuroscience from the NYC perspective, with John Kubie (Downstate, NYC), including the early days of Downstate's Hippocampus Group (incl. Ranck, Muller, Kubie, Fenton), finding head direction cells with James Ranck and John's amazing career of work in memory and navigation since. Hippocampus research conversation. Slides can be seen at: https://loveandphilosophy.com/beyond-...

    Neuroscientist John Kubie and philosopher Andrea Hiott discuss the development of cognitive neuroscience, emphasizing the discovery of place cells and their critical role in spatial navigation and memory. It explores the conversations between various experts on their journey from psychology and biology to groundbreaking neuroscience discoveries. Topics include the intricate roles of place cells, head direction cells, grid cells, and border cells in the brain's navigation system, and how these discoveries have been crucial in understanding how animals, including humans, navigate and remember environments. The script also examines the dual-layer nature of memory, the hippocampus' function in memory consolidation, and the broader implications for understanding consciousness and self. Furthermore, it highlights the challenges in pioneering neuroscience, the impact of technological advancements, and explores the continuity between basic navigational instincts and complex cognitive processes, offering a comprehensive overview of the field's current state and its future directions.

  • Rethinking Neuroscience: Labels or Learning Systems?
    Jun 6 2024

    Could we have a unified theory of the hippocampus? A clip from Brain GPT discussion in the episode with UCL Brad Love: • Brain GPT & Rethinking Neuroscience w...
    Here the spotlight is on the hippocampus and its roles in memory, navigation, and knowledge acquisition. Brad has built models that might show navigation and memory as interconnected aspects of a general learning system that is not dependent on giving neurons specific functional names, or at least not only one name.

    The discussion delves into the historical perspective of the hippocampus being studied primarily for memory, and the evolution of understanding its functions in navigation through the discovery of place cells, grid cells, and border cells. Brad emphasizes the potential oversimplification in neuroscience of labeling and categorizing functions within the brain and advocates for a broader, more integrated approach to understanding brain functions, challenging the traditional 'Eureka' moments of discovering new cell types like 'Jennifer Aniston cells'. Instead, we might think of there being an underlying mechanisms of the hippocampus and the brain's learning processes that is named differently according to context and task. The script culminates in a call for nuanced scientific inquiry that avoids oversimplification by appreciating the brain's complexity and its capacity for multifaceted functions and adaptability.
