The cerebrum (pl.: cerebra), telencephalon or endbrain [1] is the largest part of the brain, containing the cerebral cortex (of the two cerebral hemispheres) as well as several subcortical structures, including the hippocampus, basal ganglia, and olfactory bulb. In the human brain, the cerebrum is the uppermost region of the central nervous system.
The Human Brain Project is a large scientific research project, starting in 2013, which aims to simulate the complete human brain. The field of neuroscience encompasses all approaches that seek to understand the brain and the rest of the nervous system. [8]
The human brain can feature in science fiction, with themes such as brain transplants and cyborgs (beings with features like partly artificial brains). [225] The 1942 science-fiction book (adapted three times for the cinema) Donovan's Brain tells the tale of an isolated brain kept alive in vitro , gradually taking over the personality of the ...
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% is made up of the three/four-layered allocortex. [2] There are between 14 and 16 billion neurons in the cortex. [2]
The development of the nervous system in humans, or neural development, or neurodevelopment involves the studies of embryology, developmental biology, and neuroscience.These describe the cellular and molecular mechanisms by which the complex nervous system forms in humans, develops during prenatal development, and continues to develop postnatally.
The central nervous system (CNS) is the part of the nervous system consisting primarily of the brain and spinal cord.The CNS is so named because the brain integrates the received information and coordinates and influences the activity of all parts of the bodies of bilaterally symmetric and triploblastic animals—that is, all multicellular animals except sponges and diploblasts.
The human cerebral cortex divided into Brodmann areas on the basis of cytoarchitecture. Cytoarchitecture (from Greek κύτος 'cell' and ἀρχιτεκτονική 'architecture'), also known as cytoarchitectonics , is the study of the cellular composition of the central nervous system's tissues under the microscope.
The pedunculopontine nucleus (PPN) or pedunculopontine tegmental nucleus (PPT or PPTg) is a collection of neurons located in the upper pons in the brainstem. [1] [2] It is involved in voluntary movements, [3] arousal, and provides sensory feedback to the cerebral cortex and one of the main components of the ascending reticular activating system.
