sulcibegins
Sulcibegins is a neologism that has appeared in discussions of brain development and computational modeling to denote the initial onset of sulcation, the process by which the cerebral cortex develops grooves known as sulci. The term is not part of standard neuroanatomy or established morphogenesis nomenclature, and its precise interpretation varies among writers.
Etymology-wise, sulcibegins combines sulcus, the Latin word for a furrow, with begins, signaling the start of
