garnered increasing attention in the academic, religious, scientific, and popular worlds. It is the field of study that explores the intersection between the brain and religious and spiritual phenomena. However, there have been no extensive attempts at exploring specifically how Catholic religious thought and experience may intersect with neurotheology. The purpose of 'Catholic Neurotheology' is to fully engage this groundbreaking area. Topics are related to a neurotheological approach to the foundational Catholic beliefs derived from Scripture and Tradition, an exploration of the various elements of Catholicism and of Catholic rituals and practices, and a review of Catholic spiritualities and mysticism. Specific Catholic scholars are considered in terms of the relationships among their ideas/teachings and different brain processes. 'Catholic Neurotheology' engages these topics in an easy-to-read style and incorporates scientific, religious, philosophical, and theological aspects of the emerging field of neurotheology. By reviewing the concepts in a stepwise, simple, yet thorough discussion, readers regardless of their background will be able to understand the complexities and breadth of neurotheology from a Catholic perspective. More broadly, issues include a review of the neurosciences and neuroscientific techniques; religious and spiritual experiences; theological development and analysis; liturgy and ritual; philosophy, epistemology, and ethics; and social implications, all from a Catholic perspective.
