The hippocampus is essential for forming new memories, such as what one ate for lunch or a recent conversation. In addition, inter-observer agreement on the rating scale was evaluated using the statistic method11. It is widely accepted that each of these regions has a unique functional role in the information processing of the hippocampus, but to date, the specific contribution of each region is poorly understood. Hippocampus | Definition, Location, Function, & Facts In more extreme cases the cysts size may cause the head to change shape or may displace the surrounding lobes of the brain. The relationship between complex partial seizure and temporal fissure cyst is controversial [2].
