CINGULATE GYRUS Meaning and
Definition
-
The cingulate gyrus, also known as the cingulate cortex, is a part of the brain that is located in the medial surface of the cerebral hemisphere, specifically in the frontal and parietal lobes. It is named after its curved shape resembling a belt or girdle.
Functionally, the cingulate gyrus plays a crucial role in various cognitive processes and emotional regulation. It is involved in attention, decision-making, empathy, conflict monitoring, and memory. The cingulate gyrus is particularly associated with the limbic system, which is the emotional center of the brain, and it helps regulate emotional responses and social behavior.
Anatomy-wise, the cingulate gyrus is divided into two main regions: the anterior cingulate cortex (ACC) and the posterior cingulate cortex (PCC). The ACC is primarily linked to cognitive control, emotions, and pain processing. It also contributes to attentional processes, reward anticipation, and decision-making. The PCC, on the other hand, is implicated in memory retrieval, self-reflection, and navigation.
Disruptions in the cingulate gyrus have been linked to various psychiatric and neurological disorders. For example, dysfunction in the ACC has been associated with attention deficit hyperactivity disorder (ADHD), obsessive-compulsive disorder (OCD), depression, and schizophrenia. Meanwhile, abnormalities in the PCC have been observed in individuals with Alzheimer's disease and other forms of dementia.
In summary, the cingulate gyrus is an integral part of the brain involved in various cognitive and emotional processes, including attention, decision-making, memory, and emotion regulation. It consists of the ACC and PCC, each with distinct roles and functions within the brain.

Etymology of CINGULATE GYRUS
The etymology of the term "cingulate gyrus" can be understood by breaking it down into its two constituent parts: "cingulate" and "gyrus".
1. "Cingulate" originates from the Latin word "cingulum", meaning "belt" or "girdle". It refers to the circular shape of the region that wraps around the corpus callosum, resembling a belt or girdle-like structure. "Cingulum" is derived from the Latin verb "cingere", which means "to gird" or "to encircle".
2. "Gyrus" comes from the Greek word "gyros", meaning "ring" or "circular motion". In the context of neuroscience, "gyrus" refers to the ridges or convolutions on the surface of the brain.
