The purpose of this report is to update a previous review on the neuromodulation technologies of transcranial magnetic stimulation and transcranial electrical stimulation (Kelley et al., 2019). Ongoing work within the U.S. Army is investigating means of sustaining or enhancing Soldier performance. As neuroenhancement is a rapidly evolving field, it is imperative to stay up-to-date on the current state of the science. As such, this report includes studies performed between 2018 and 2022 that met our specific inclusion criteria. This report specifically focuses on studies that investigate the potential role for the neuromodulation technologies of transcranial magnetic stimulation (TMS) and transcranial electrical stimulation (tES) to enhance cognitive function. In particular, we are interested in several specific aspects of cognition that relate directly to the daily function of the Soldier including working memory, attention, inhibition, cognitive control, and reasoning/decision making. Here, we have discussed the feasibility and practicality aspects of implementing this technology in the military setting as well as the current limitations and remaining questions within the research field of transcranial stimulation pertaining to enhancing cognitive performance.
