GYRUS FORNICATUS Meaning and
Definition
-
Gyrus fornicatus is a term used in neuroscience to refer to a specific region of the brain found in the limbic system, specifically in the mesial (inner) surface of the cerebral hemisphere. Also known as the cingulate gyrus, it is a prominent structure that is considered part of the limbic cortex.
The gyrus fornicatus is characterized by its location above the corpus callosum, curving around the corpus callosum and forming a "C" shape. It is divided into four parts: the anterior, posterior, retrosplenial, and isthmic regions. These divisions are based on their anatomical locations and connections with other brain regions.
Functionally, the gyrus fornicatus is involved in various cognitive processes and emotions. It plays a crucial role in regulating emotional responses, memory formation and retrieval, decision-making, and attention. It is also involved in reward processing and social interaction, making it an essential region for social cognition.
Together with other limbic structures, such as the hippocampus and amygdala, the gyrus fornicatus forms a network that is critical for emotional regulation and the formation of memories. Dysfunction or damage to this region can result in cognitive impairments, mood disorders, and memory deficits.
Overall, the gyrus fornicatus is a vital brain structure involved in various cognitive and emotional processes, contributing to an individual's overall cognitive and emotional functioning.

Fornicate convolution, limbic lobe, falciform lobe, a long, ring-like convolution on the mesial aspect of the hemisphere, encircling the corpus callosum; its various parts are called g. cinguli, isthmus, g. hippocampi, and uncus. (The term for gyrus fornicatus of the older nomenclature is gyrus cinguli.).

Etymology of GYRUS FORNICATUS
The word gyrus fornicatus is a Latin term that can be broken down into two parts: gyrus and fornicatus.
1. Gyrus comes from the Latin word gyros, which means circle or ring. In anatomy, a gyrus refers to a ridge or convolution on the surface of the brain that is surrounded by grooves called sulci.
2. Fornicatus is derived from the Latin word fornicatus, which is the past participle of fornicare. Fornicare means to arch over or to vault. The term fornicatus is used to describe the arched shape of an anatomical structure, often used in the context of brain anatomy.
Therefore, gyrus fornicatus can be translated to mean arched circle or vaulted convolution.
