CALCARINE SULCUS Meaning and
Definition
-
The calcarine sulcus, also known as the calcarine fissure or the calcarine groove, is a prominent and well-defined sulcus within the human brain. It is located on the medial surface of the occipital lobe in the posterior region. The sulcus runs in an antero-posterior direction and is positioned slightly above the midpoint of the occipital lobe.
The calcarine sulcus plays a crucial role in vision as it serves as the primary visual cortex, specifically the primary visual area known as V1 or Brodmann area 17. This region is responsible for initial processing of visual information received from the eyes, as it receives input from the lateral geniculate nucleus (LGN) of the thalamus. The calcarine sulcus serves as the primary recipient of these visual signals, which are subsequently distributed to other areas involved in visual processing.
The organization of the calcarine sulcus is highly specialized, exhibiting a retinotopic mapping of the visual field. This means that adjacent points on the retina send signals to adjacent points in the calcarine sulcus. The upper half of the visual field is mapped onto the lower half of the sulcus, while the lower half of the visual field is represented on the upper half of the sulcus. This specialized organization allows for efficient processing and integration of visual information.
Overall, the calcarine sulcus is a crucial structure in the brain responsible for initial visual information processing, making it essential for normal visual perception and awareness.
