GYRUS HIPPOCAMPI Meaning and
Definition
-
The gyrus hippocampi, commonly known as the hippocampal gyrus, is a term used in neuroanatomy to describe a specific structure located in the brain. It is a part of the medial temporal lobe and is situated on the inner side of the brain's cerebral hemisphere. The term "gyrus" refers to the ridge or fold on the brain's surface, while "hippocampi" is derived from the Greek word for seahorse, due to its resemblance to the shape of the animal.
The gyrus hippocampi is primarily associated with memory formation and consolidation, as well as spatial navigation. It plays a crucial role in the brain's ability to process and store information, particularly for long-term memory. This structure is involved in the transfer of information from short-term memory to long-term memory, and is essential for the formation of declarative memories, which are memories related to facts and events.
The gyrus hippocampi is composed of different subregions, including the dentate gyrus, hippocampus proper, and subiculum. Each of these subregions contributes to different aspects of memory processing. The dentate gyrus, for example, is involved in pattern separation, while the hippocampus proper is responsible for context and spatial memory. The subiculum acts as a transition zone connecting the gyrus hippocampi with other brain regions.
The dysfunction or damage to the gyrus hippocampi has been associated with various memory impairments, including amnesia and difficulty in forming new memories. Understanding the organization and function of the gyrus hippocampi is crucial for unraveling the mechanisms underlying memory processes and related neurological disorders.

Hippocampal convolution, a convolution lying to the inner side of each temporal lobe of the cerebrum from which it is separated by the collateral fissure; it is connected with the g. cinguli posteriorly through the isthmus and forms the lower portion of the g. fornicatus (limbic lobe).

Etymology of GYRUS HIPPOCAMPI
The word "gyrus hippocampi" consists of two parts: "gyrus" and "hippocampi".
1. Gyrus: The term "gyrus" comes from the Latin word "gyrus", meaning "ring" or "circle". It refers to the convolutions or folds on the surface of the cerebral cortex in the brain. These convolutions increase the surface area of the brain, allowing for a larger number of neurons and more complex cognitive functions.
2. Hippocampi: The term "hippocampi" is the plural form of "hippocampus", which is a structure in the brain. "Hippocampus" comes from the Greek word "hippokampos", which translates to "seahorse". The name was given to this brain structure because of its resemblance to the shape of a seahorse.
