Bear explains how the visual cortex became a model system for uncovering the synaptic mechanisms that allow the brain to change, adapt, and learn, especially during early development.\nWe explore how visual experience shapes neural circuits, why the brain undergoes critical periods of heightened plasticity, and what classic experiments in visual deprivation revealed about how connections are strengthened or lost. Bear walks us through the discovery of binocular vision in the cortex, the role of inhibition in closing critical periods, and how these ideas reshaped our understanding of learning and memory.\nThe conversation also covers modern views of cortical plasticity, including perceptual learning, visual recognition memory, and how the brain distinguishes familiar from novel stimuli. Bear discusses how insights from vision extend to broader questions about brain development, neurological disorders such as amblyopia, and whether adult plasticity can be reopened.\nWhether you’re interested in neuroscience, brain development, neuroplasticity, learning and memory, or the biology of vision, this episode offers a clear and authoritative look at how experience shapes the brain at the level of neural circuits and synapses.\nFollow us for more technical interviews with the world’s greatest scientists:\nTwitter: https://x.com/632nmPodcast\nInstagram: https://www.instagram.com/632nmpodcast?utm_source=ig_web_button_share_sheet&igsh=ZDNlZDc0MzIxNw==\nLinkedIn: https://www.linkedin.com/company/632nm/about/\nSubstack: https://632nmpodcast.substack.com/\nFollow our hosts!\nMikhail Shalaginov: https://x.com/MYShalaginov\nMichael Dubrovsky: https://x.com/MikeDubrovsky\nXinghui Yin: https://x.com/XinghuiYin\nSubscribe:\nApple Podcasts:...","thumbnail_url":"https://img.transistorcdn.com/GydlQqnUybBqv7mvA947eCIsz_CyOG8rEnboLv3Hs_I/rs:fill:0:0:1/w:400/h:400/q:60/mb:500000/aHR0cHM6Ly9pbWct/dXBsb2FkLXByb2R1/Y3Rpb24udHJhbnNp/c3Rvci5mbS8yOGMz/YTliMThlODIyYzYw/OGVjOWNiZWNlNmQ1/ZmQ0Ni5qcGc.webp","thumbnail_width":300,"thumbnail_height":300}
