There is a Vietnamese proverb that reads "Brothers and sisters are as close as hands and feet." Theo and Stavros Zanos are perhaps one of the best personifications of this notion. They are independent, they accomplish vastly different things, yet they are perfectly paired and, at the end of the day, part of the same system. So, grab an espresso from Theo's lab and join us for a chat with the brothers of The Feinstein's Institute for Bioelectronic Medicine.

S2 E7: O Brother, Where Art Thou? - Stavros Zanos and Theo Zanos on SKRAPS

Dr. Stavros Zanos is an Assistant Professor at the Feinstein Institute for Medical Research. In his Translational Neurophysiology lab, they develop methods and techniques to interface with, stimulate and record the vagus nerve to understand how it controls physiological functions, with the end goal of developing therapies for diseases. In this episode, Dr. Stavros Zanos discusses his recent publication regarding anodal blocking in the vagus nerve.    Top three takeaways:  The selectivity capability between afferent and efferent fibers will be used to create better therapies using vagus nerve stimulation.  The vagotomy technique proved to be useful when assessing the characteristics of the fibers as afferent or efferent.   A major challenge of this project was recording the effects of the vagus nerve stimulation due to their complexity.     [0:00] Ladan introduces the episode and the guest, Dr. Stavros Zanos.    [2:10] Dr. Zanos tells how his experiences led him to the Feinstein Institute.    [4:10] His focus has been on engineering implants, understanding the physiological effects of bioelectronic therapies, and testing animal models to be able to create chronic implants for testing therapies.   [7:00] The anodal block technique used in their publication is a way of biasing the activation of afferent and efferent fibers to effectively treat different diseases.   [9:30] At the lowest intensity of stimuli, the larger fibers get engaged first; as you increase the intensity, smaller fibers are able to be engaged.    [13:30] Judging by the physiological changes that occurred during a vagotomy, afferent and efferent fibers are indexed.    [16:00] Dr. Zanos cautions researchers to always evaluate the translatability of their devices from animals to humans.    [18:00] Another major focus of the lab is to develop chronic implants in animals, understand how to make them last longer, and then judge how the interface changes over time.    [20:30] By increasing the intensity of stimulation, there is a greater amount of potentials going in one direction and blockage of the other potentials.   [24:10]  The cycle of innovation when it comes to medical devices ranges between five to 10 years.
