Neurosalience #S5E14 with Rosanna Olsen - The hippocampus, aging, memory, and discovery

Peter Bandettini interviews Dr. Rosanna Olsen, a senior scientist at the Rotman Research Institute and the University of Toronto. She is pioneering what we know about human memory and its associated structures, primarily focusing on the hippocampus, the role it plays, and how it changes with age and neurological diseases. Her work has shed light on how the hippocampus facilitates the flexible binding and comparison of new and existing information. She has also shown how visual exploration reveals memory processes, and has uncovered promising early dementia biomarkers based on measures of visual exploration and hippocampus. Dr. Olsen is also a leader in education. She is co-lead of the Research Training Center in Toronto, disseminating essential knowledge and skills to younger scientists, and is chair-elect of the OHBM education committee. She is also the leader of a consortium organized to reach a consensus on hippocampus segmentation. Lastly she's an avid and accomplished runner, having run the Boston Marathon, as well as many others.We hope you enjoy the conversation! Episode ProducersOmer Faruk GulbanXuqian Michelle Li

Join Peter Bandettini as he sits down with Seiji Ogawa, the visionary scientist behind the discovery of BOLD (blood oxygenation level-dependent) contrast fMRI. In this insightful conversation, Dr. Ogawa reflects on his groundbreaking work, the evolution of neuroimaging, and the challenges of translating fMRI into clinical practice. 1. Ogawa’s Early Journey – From Stanford to Bell Labs, and the influences that shaped his career. 2. The Discovery of BOLD fMRI – How experiments with hemoglobin oxygenation laid the foundation for modern neuroimaging. 3. Impact on Neuroscience – Why fMRI became a cornerstone in understanding brain function. 4. Challenges in Clinical Translation – Variability and reliability in single-subject analyses. 5. Scientific Reflections – Ogawa’s thoughts on curiosity, persistence, and the art of discovery. 6. Future Directions – Exploring brain interactions, neurovascular coupling, and innovations in imaging techniques. Notable Quotes: “If you can look into your brain without opening your skull… that’s a great thing.” “The important thing is to know what is important.” “Many phenomena don’t last long, but fMRI has proven to be enduringly significant.” Seiji Ogawa’s contributions have left an indelible mark on neuroscience, inspiring researchers worldwide. Don’t miss this fascinating exploration of his life, work, and ongoing curiosity about the mysteries of the human brain. Episode Producers Omer Faruk Gulban Nagashree Thovinakere

Our guest today is Dr. Vesa Kiviniemi, a radiologist and researcher at Oulu University in Finland. Dr. Kiviniemi’s recent focus has been on using an extremely high-speed MRI technique called MREG. This technique allows for the collection of an entire volume of data with a TR of just 100 milliseconds, using a stack-of-spirals approach. The reason he values this technique so much is that it enables him to examine various types of brain pulsations, including cardiac and respiratory pulsations, as well as what he refers to as glymphatic or CSF pulsations. In this episode, Dr. Kiviniemi explores how he has applied this technique in his research. He also discusses the history of our understanding of the glymphatic system, its potential functions, the many unknowns surrounding it, and the opportunities it presents for future research. Among other topics, he explains why using this high-speed technique might complement—or in some cases even be better than—slower approaches in certain ways. We hope you enjoy the conversation!

This episode is unique in the sense that it’s actually a talk Peter gave during the OHBM 2024 meeting, specifically during the education session on communicating science. Peter wanted to share this talk because it focuses on the podcast and his own approach to creating it. He discusses his philosophy, heuristics, what he considers important about podcasting, and why he enjoys doing it. The talk emphasizes the value of conversation and explains how the podcast showcases the human side of scientific investigators and the stories behind their research. We hope you enjoy it!
