Deep Dive into tDCS Methodology: Key Considerations and Protocol Designs

In this episode of The Neurostimulation Podcast, we review chapter seven of the Practical Guide to Transcranial Direct Current Stimulation (tDCS), which focuses on the methodological considerations for selecting tDCS protocols and devices. We discuss important factors such as electrode size and placement, stimulation intensity and duration, and the timing of tDCS sessions. The episode also covers the decision-making framework for clinicians, population-specific adjustments, and the comparison between clinic-based and home-based device use. The role of behavioral tasks during tDCS and the importance of methodological rigor in tDCS research and clinical practice are emphasized. Listeners are encouraged to understand the crucial elements of proper tDCS setup to ensure effective and replicable results.
