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 ...
Cortical areas: Limbic lobe. Orbitofrontal cortex: a region in the frontal lobe involved in the process of decision-making. Piriform cortex: part of the olfactory system. Entorhinal cortex: related to memory and associative components. Hippocampus and associated structures: play a central role in the consolidation of new memories.
In the developing chordate (including vertebrates), the neural tube is the embryonic precursor to the central nervous system, which is made up of the brain and spinal cord. The neural groove gradually deepens as the neural folds become elevated, and ultimately the folds meet and coalesce in the middle line and convert the groove into the closed ...
The fourth ventricle has a characteristic diamond shape in cross-sections of the human brain. It is located within the pons or in the upper part of the medulla oblongata. CSF entering the fourth ventricle through the cerebral aqueduct can exit to the subarachnoid space of the spinal cord through two lateral apertures and a single, midline ...
The brain is the central organ of the human nervous system, and with the spinal cord makes up the central nervous system. The brain consists of the cerebrum, the brainstem and the cerebellum. It controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sense organs, and making ...
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 century.
The cerebral cortex is the outer covering of the surfaces of the cerebral hemispheres and is folded into peaks called gyri, and grooves called sulci. In the human brain, it is between 2 and 3-4 mm. thick, [ 8] and makes up 40% of the brain's mass. [ 2] 90% of the cerebral cortex is the six-layered neocortex whilst the other 10% made up of three ...
Scheme of the roof of the fourth ventricle. The hindbrain, rhombencephalon (shaped like a rhombus) or lower brain [1] is a developmental categorization of portions of the central nervous system in vertebrates. It includes the medulla, pons, and cerebellum. Together they support vital bodily processes.
