What does the alveus of hippocampus consist of?

The alveus of the hippocampus consists of fibers leaving the hippocampus. It serves as a pathway for axons that carry output signals from the hippocampus to other regions of the brain. Particularly, the alveus collects the main output fibers from the pyramidal neurons located in the hippocampal formation and channels them towards the fimbria, which ultimately contributes to the fornix—a major output tract of the hippocampus.

Understanding the role of the alveus is crucial in neuroanatomy, as it highlights how the hippocampus communicates with other brain areas, especially those involved in memory and learning processes. This functional aspect emphasizes the importance of the fibers in transmitting essential information beyond the hippocampus to facilitate cognitive functions.
