The parahippocampal gyrus, also known as hippocampal gyrus, is a region of the brain with a grey matter, and it is an important part of the limbic system which surrounds the hippocampus. The parahippocampal gyrus plays a vital role in retrieval and memory encoding. It is found that the parahippocampal is involved in some cases of hippocampal sclerosis. The entorhinal and perirhinal cortices are found in the anterior part of the gyrus. The parahippocampal cortex is the region where both the posterior parahippocampal gyrus and the medial portion of the fusiform gyrus are found. Scene recognition- The inferior temporo-occipital cortex consists of the PPA or Parahippocampal place area in the middle that is also the sub-region of the parahippocampal cortex. The PPA plays a significant role in recognizing environmental scenes and rather than human faces. Studies suggest that this area of the brain becomes very active when humans view landscapes, rooms, or cityscapes. Additional research also shows that the right hippocampal gyrus can do more than just recognizing visual contexts. A research made by a California based group shows that it can play an important role in recognizing the verbal elements in the communication.
