Neurological conditions conquer the world; they are the leading cause of disability and the second leading cause of death worldwide, and they appear all around the world in every age group, gender, nationality, and socioeconomic class. Despite the growing evidence of an immense impact of perturbations in neuroenergetics on overall brain function, only little is known about the underlying mechanisms. Especially human insights are sparse, owing to a shortage of physiologically relevant model systems. With this perspective, we aim to explore the key steps and considerations involved in developing an advanced human in vitro model for studying neuroenergetics. We discuss biological and technological strategies to meet the requirements of a predictive model, aiming at providing a guide and inspiration for future in vitro models of neuroenergetics.
