The occipital lobe is one of the four major lobes of the cerebral cortex in the brain of mammals. The name derives from its position at the back of the head, from the Latin ob, 'behind', and caput, 'head'. The occipital lobe is the visual processing center of the mammalian brain containing most of the anatomical region of the visual cortex. [1]
The parietal lobe is positioned above the occipital lobe and behind the frontal lobe and central sulcus.. The parietal lobe integrates sensory information among various modalities, including spatial sense and navigation (proprioception), the main sensory receptive area for the sense of touch (mechanoreception) in the somatosensory cortex which is just posterior to the central sulcus in the ...
The lobes are classified based on their overlying neurocranial bones. [4] A smaller lobe is the insular lobe , a part of the cerebral cortex folded deep within the lateral sulcus that separates the temporal lobe from the parietal and frontal lobes, is located within each hemisphere of the mammalian brain.
Asymmetry in the Sylvian fissure (also known as the lateral sulcus), which separates the frontal and parietal lobes from the temporal lobe, was one of the first incongruencies to be discovered. Its anatomical variances are related to the size and location of two areas of the human brain that are important for language processing, Broca's area ...
It can also refer to the occipital operculum, part of the occipital lobe. The insular lobe is a portion of the cerebral cortex that has invaginated to lie deep within the lateral sulcus. It sits like an island (the meaning of insular) almost surrounded by the groove of the circular sulcus and covered over and obscured by the insular opercula.
Vision: The visual area known as V1, striate cortex, or (primary visual cortex, Brodmann area 17) is located on the calcarine sulcus deep within the inside folds of the occipital lobe. Hearing: The primary auditory cortex is located on the transverse gyri that lie on the back of the superior temporal convolution of the temporal lobes.
In human anatomy, the occipital lobes and the back of the head are posterior but not caudal to the frontal lobes and the face. "Superior" and "inferior" are adjectives from human anatomy, respectively meaning towards to top of the head or the soles of the feet when standing.
The cuneus (from Latin 'wedge'; pl.: cunei) is a smaller lobe in the occipital lobe of the brain. The cuneus is bounded anteriorly by the parieto-occipital sulcus and inferiorly by the calcarine sulcus.
