CORNUAMMONIS Meaning and
Definition
-
Cornu Ammonis (CA), also known as the Ammon's horn, refers to a distinct region of the hippocampus in the brain. The term "cornu ammonis" is derived from Latin, with "cornu" meaning "horn" and "Ammonis" referring to the Egyptian god Amun. This name was given to the structure due to its curved shape resembling a ram's horn.
CA is a critical component of the hippocampal formation, playing a fundamental role in memory and learning processes. It consists of four distinct subregions, numbered CA1 to CA4, each with specific functions. CA1 is responsible for integrating information from the dentate gyrus and other cortical inputs to form spatial and episodic memories. CA2 assists in pattern separation and storage of social information, while CA3 acts as a memory associator, consolidating information by connecting synapses. CA4, often referred to as the hilus, plays a significant role in regulating excitatory input to the hippocampus.
The cornu ammonis region is composed of densely packed pyramidal neurons, which possess unique properties that are key to the information processing capabilities of the hippocampus. These neurons exhibit specific activity patterns during different phases of memory formation and replay these patterns during memory recall.
Overall, the cornu ammonis is integral to our ability to form and retrieve memories, making it a crucial area for understanding neurological disorders related to memory deficits.
