The frontal lobe is the largest lobe of the brain and makes up about a third of the surface area of each hemisphere. [3] On the lateral surface of each hemisphere, the central sulcus separates the frontal lobe from the parietal lobe. The lateral sulcus separates the frontal lobe from the temporal lobe. The frontal lobe can be divided into a ...
The lobes of the brain are the major identifiable zones of the human cerebral cortex, and they comprise the surface of each hemisphere of the cerebrum. The two hemispheres are roughly symmetrical in structure, and are connected by the corpus callosum. They traditionally have been divided into four lobes, but are today considered as having six ...
The major sulci and gyri mark the divisions of the cerebrum into the lobes of the brain. The four major lobes are the frontal, parietal, occipital and temporal lobes. Other lobes are the limbic lobe, and the insular cortex often referred to as the insular lobe. There are between 14 and 16 billion neurons in the human cerebral cortex. [2]
Each electrode placement site has a letter to identify the lobe, or area of the brain it is reading from: pre-frontal (Fp), frontal (F), temporal (T), parietal (P), occipital (O), and central (C). Note that there is no "central lobe"; due to their placement, and depending on the individual, the "C" electrodes can exhibit/represent EEG activity ...
The brain is the central organ of the human nervous system, and with the spinal cord makes up the central nervous system. It consists of the cerebrum, the brainstem and the cerebellum. The brain controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sense organs, and making ...
68596. Anatomical terms of neuroanatomy. [edit on Wikidata] A Brodmann area is a region of the cerebral cortex, in the human or other [citation needed] primate brain, defined by its cytoarchitecture, or histological structure and organization of cells. The concept was first introduced by the German anatomist Korbinian Brodmann in the early 20th ...
Hence, there is overlap of structures in the limbic system and in other classifications of brain structures. The following areas have been considered part of the limbic system. [2] [3] Cortical areas: Limbic lobe; Orbitofrontal cortex: a region in the frontal lobe involved in the process of decision-making; Piriform cortex: part of the ...
Anatomical terms of neuroanatomy. [edit on Wikidata] The orbitofrontal cortex (OFC) is a prefrontal cortex region in the frontal lobes of the brain which is involved in the cognitive process of decision-making. In non-human primates it consists of the association cortex areas Brodmann area 11, 12 and 13; in humans it consists of Brodmann area ...
