Abstract : Recording neural activity that originates from action potential dynamics has long been a major pursuit in neuroscience. While electrophysiology is easier to perform, magnetophysiology does not require intimate contact or charge transfer with neural tissue, avoids tissue-based distortions, and measures a signal with directional information. This makes magnetic recordings an interesting avenue for developing non-implantable neural devices. In this talk, I will present our recent results on the in vitro detection of neuronal activity emerging from spinal cord slices under physiological conditions at room temperature, without magnetic shielding, as well as our first steps towards in-vivo detection of neural signals from mice and humans.
Biography : Lucas Perez is Professor of Applied Physics at Universidad Complutense de Madrid and Associate Researcher at IMDEA Nanociencia (Madrid, Spain). His research activities are mainly focused on understanding and controlling the 3D magnetic configuration and the magnetization dynamics of cylindrical nanowires. He is also involved in applied research, focused on the development of rare-earth-free permanent magnets. In recent years, he has broadened his interests to the field of biomedical technology, where he is actively engaged in developing nanotechnology for interaction with neural systems.
