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 primary visual cortex is the most studied visual area in the brain. In mammals, it is located in the posterior pole of the occipital lobe and is the simplest, earliest cortical visual area. It is highly specialized for processing information about static and moving objects and is excellent in pattern recognition. Moreover, V1 is ...
Brodmann area 19, or BA 19, is part of the occipital lobe cortex in the human brain.Along with area 18, it comprises the extrastriate (or peristriate) cortex. In humans with normal sight, extrastriate cortex is a visual association area, with feature-extracting, shape recognition, attentional, and multimodal integrating functions.
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.
“Dementia can affect the frontal and temporal lobes [of the brain], causing issues with object recognition. It can also affect the occipital lobes, causing issues with visual processing.
Brodmann area 18, or BA18, is part of the occipital cortex in the human brain.It accounts for the bulk of the volume of the occipital lobe. It is known as a "Visual Association Area" or V2 and is a first stage in processing or feature extraction of retinotopic images from V1.
The parietal-temporal-occipital (PTO) association area, also referred to as the temporo-parieto-occipital (TPO) junction, is an area within the cerebral cortex where the parietal, temporal and occipital lobes meet. [1] High level of interpreting meaningful signals in the surrounding sensory area. They have functional subareas:
