PLANUM OCCIPITALE Meaning and
Definition
-
Planum occipitale, also known as the occipital plane, is a term used to describe a specific area located in the posterior region of the human brain. It is situated within the occipital lobe, the most posterior lobe of the cerebral cortex, which is responsible for processing visual information.
The planum occipitale is situated on the lateral surface of the occipital lobe and is found just above the calcarine sulcus, which is a prominent sulcus that divides the occipital lobe into superior and inferior halves. It encompasses a region that extends towards the posterior margin of the brain, making up a significant part of the occipital lobe.
Functionally, the planum occipitale plays a crucial role in visual processing. It serves as the primary visual cortex, also referred to as V1 or the striate cortex, which is responsible for receiving and processing visual information from the eyes. It serves as the initial stage of visual processing, where basic features such as orientation, color, and motion of visual stimuli are analyzed before being conveyed to higher-order visual areas for further processing.
Studies have shown that the planum occipitale exhibits a high level of plasticity and is capable of reorganizing itself depending on the visual input it receives. Neuroimaging techniques, such as functional magnetic resonance imaging (fMRI), have allowed researchers to map and study the activity patterns and connectivity of the planum occipitale in order to gain a deeper understanding of visual perception and cognition.

Etymology of PLANUM OCCIPITALE
The term "planum occipitale" has its origin in Latin.
- "Planum" comes from the Latin word "planus", which means "flat or level". It is derived from the Proto-Indo-European root "*pleh₁-" meaning "to spread or smooth".
- "Occipitale" is the neuter form of the Latin word "occipitalis", which is derived from "occiput" and refers to the back of the head. "Occiput" is a combination of two Latin words: "ob" which means "against" and "caput" meaning "head".
Therefore, "planum occipitale" can be translated as "flat region at the back of the head" or "level area of the occiput". It is often used in anatomy to refer to a specific area on the posterior part of the skull.
