Conversations on Bionics and Pain

This show is about engineering and medical developments related to bionics and pain, particularly the use of science and technology to restore function in the human body and alleviation of pain. The episodes come in two formats. The most common will be long interviews with established researchers about their work and its historical context, such as the state-of-the-art at the time and the motivations behind their developments. The second format is shorter interviews with the authors of recent scientific articles about their findings. In both formats, the guests will talk about their career paths, their views on current challenges in the field, and the opportunities ahead. We will also talk about their views on science and the social aspects surrounding it, and we will not shy away from controversial topics. The target audience for this podcast is students and professionals interested on pain, bionics, biomechatronics, neural engineering, computer brain interfaces, biomedical engineering, and such topics where medicine and engineering partner up. The show is hosted by Assoc. Prof. Max Ortiz Catalan, Ph.D., who is the Director of the Center for Bionics and Pain Research (www.cbpr.se) and known for his work on prosthetic limbs and phantom limb pain.

  1. A2 Somatosensory Plasticity | Prof. Sliman Bensmaia

    A2 Somatosensory Plasticity | Prof. Sliman Bensmaia

    Episode on the article “Chronic Use of a Sensitized Bionic Hand Does Not Remap the Sense of Touch” (Ortiz-Catalan et al., Cell Reports, 2020). I discuss with Prof. Sliman Bensmaia at the University of Chicago, with whom we published this article, how the long-term used of a bionic hand that elicits tactile sensory feedback in a location distinct to that observed by the user, provided evidence to the inability of the brain to change enough as to generate an experience that solves the mismatch. In other words, we showed a hard constraint to brain plasticity in the somatosensory system.

  2. 2 Prof. Todd Kuiken | Targeted Muscle Reinnervation

    26/02/2021

    2 Prof. Todd Kuiken | Targeted Muscle Reinnervation

    Prof. Todd Kuiken developed Targeted Muscle Reinnervation (TMR) – a surgical method to rewire the nervous system of people with amputations to better interface with prosthetic limbs. He is the Emeritus Director of the Regenstein Foundation Center for Bionic Medicine at the Sherly Ryan AbilityLab and an Emeritus Professor at Northwestern University. In addition to his contributions to the treatment of amputees, we talked about how great multidisciplinary medical and engineering teams can be created and the importance of having a clear direction. He also shared some insights on one of the hardest aspects of research - how to decide when to terminate projects and reject bad ideas, and we wrapped up with advices for students. Interview by Dr. Max Ortiz Catalan, Ph.D., Bionics Professor and Director of the Center for Bionics and Pain Research (Social media: FB, TW, IG, and LI).

  3. 1 Prof. Gerald E. Loeb | Neuroprostheses

    01/01/2021

    1 Prof. Gerald E. Loeb | Neuroprostheses

    Interview with Dr. Gerald E. Loeb, Professor on Biomedical Engineering and Neurology at the University of Southern California in L.A., USA. He has written hundreds of scientific articles and holds over 70 patents on medical devices (google scholar). He has conducted pioneer work on motor, visual, and auditory neuroprostheses, from basic and translational research to entrepreneurship for making such technologies available to patients. In this interview, we discuss his career path, contributions to different neuroprostheses, and the challenges faced during clinical implementation and commercialization. We also discuss the reasons to conduct a Ph.D. and subsequent career options. We finalize with a discussion on the human body as a machine (or not), and on descriptive and normative views of our jobs in society. Interview by Dr. Max Ortiz Catalan, Assoc.
