Fasciculus longitudinals inferior, also known as the inferior longitudinal fasciculus, is a neural pathway within the human brain that plays a crucial role in visual processing and language comprehension. Its primary function involves connecting the occipital and temporal lobes, facilitating communication between these regions. Although "fasciculus longitudinals inferior" is the preferred terminology, there are various synonyms to refer to this neural bundle, including the posterior longitudinal fasciculus and the ventral longitudinal fasciculus. These alternative terms are commonly used interchangeably in scientific literature, highlighting the importance of this pathway in understanding cognition, memory, and information integration across different brain regions.
