Neurostimulation in closed-loop represents a promising technique for enhancing human cognitive functions. This thesis aims to explore its effectiveness in boosting the working memory (WM) of healthy individuals through virtual reality. The focus is on the improvement of specific aspects of WM such as the ability to maintain and manipulate information, sustained attention, and real-time information updating. These elements are crucial for a wide range of cognitive functions, directly impacting the efficient management of mental information, a critical aspect in daily life. Through a meticulous methodological approach, users are presented with an n-back task implemented in virtual reality with Unity, a platform that enables the development of interactive games.
