tDCS course Chapter 2 Biophysics of tDCS - #19 - Apr 26, 2025

Exploring tDCS: Unveiling the Power of Transcranial Direct Current StimulationWelcome to the Neurostimulation Podcast, hosted by Michael Passmore, clinical associate professor at the University of British Columbia. In this episode, we delve into the world of transcranial direct current stimulation (tDCS) as outlined in chapter two of the 'Practical Guide to Transcranial Direct Current Stimulation.' Learn about the biophysics behind tDCS, its non-invasive nature, and how it affects neuronal activity. We break down the intricate details of how tDCS works, its application, key parameters, and emerging technologies like HD tDCS. We also touch on its historical background, ongoing research, potential clinical applications, and its promising future in mental health, rehabilitation, and more. This episode provides a comprehensive guide for anyone interested in understanding the subtle power and extensive promise of tDCS.00:00 Introduction to the Neurostimulation Podcast02:05 Exploring Transcranial Direct Current Stimulation (tDCS)03:06 The Essence of tDCS: Simplicity with Subtle Power04:58 Understanding the Physics of Electrical Current Flow06:56 Neuronal Polarization and Plasticity08:49 Acutely vs. After Effects of tDCS11:40 Dosing tDCS: Key Parameters13:55 Modeling, Personalization, and HD tDCS15:17 Historical Roots of Electrical Stimulation16:34 Mechanistic Nuances and Open Questions17:41 Real World Potential and Clinical Applications19:21 Conclusion and Recap
