Which area significantly contributes neural signals to the hippocampus?

The entorhinal cortex plays a crucial role in providing neural signals to the hippocampus, making it a key area for memory processing and spatial navigation. This region acts as a major relay station, funneling sensory information and input from various parts of the brain, particularly the neocortex, to the hippocampus. This connection is essential for forming new memories and is evidenced by the entorhinal cortex's direct projections to the hippocampus, specifically to the dentate gyrus and CA3 regions.

In addition, the entorhinal cortex is involved in associating contextual information with memory, further enhancing its significance in memory formation. The intricate circuitry established by the entorhinal cortex enables the encoding of complex information, which is essential for the hippocampus's role in learning and memory.
