Title: Feynman Diagrams for NEventSpace

Abstract: In recent years, Feynman diagrams have been increasingly applied to the study of spike trains in neuroscience. In particular, they have been used in the context of spike-based NEvents, NEventSpace, and NeuronX theories, which treat spikes as an alphabet of elementary events that can be combined to form more complex structures. Feynman diagrams provide a powerful tool for representing the possible ways in which NEvents can be combined, and can help neuroscientists gain insights into the patterns of neural activity that underlie various cognitive functions. In this article, we discuss the use of Feynman diagrams in the context of NEventSpace, and explore their potential for advancing our understanding of the brain
