Brain Of Vladimir Lenin
The anatomical study of Vladimir Lenin's brain by the German neurologist and psychiatrist Oskar Vogt in 1924 was a significant event in the history of neuroscience. The study aimed to understand the neural basis of Lenin's political and intellectual abilities. The research was conducted at the request of the Soviet government, which wanted to prove that Lenin's supposed genius was the result of his brain's superior structure. Under Vogt's leadership, the Kaiser Wilhelm Institute for Brain Research in Berlin was established, and the study of Lenin's brain was one of the institute's first major projects. The histological analysis methods used to examine tissue samples and helped establish the procedure as a viable way of studying the brain. Though certain structural aspects in Lenin's brain had been said to contribute to heightened cognitive ability, Vogt was nonetheless unable to identify any particular region within Lenin's brain which provided structural proof to Lenin's genius a ...

Vogt Lenin
An , sometimes simply advocate, (German, ), or (French, ), was a type of medieval office holder, particularly important in the Holy Roman Empire, who was delegated some of the powers and functions of a major feudal lord, or for an institution such as an abbey. They typically had responsibility for the "comital" functions which defined the office of early medieval "counts", such as taxation, recruitment of militias, and maintaining law and order. This type of office could apply to specific agricultural lands, villages, castles, and even cities. In some regions, advocates came to be governors of large provinces, sometimes distinguished by terms such as . In different parts of medieval Europe, the term advocate developed different meanings, and other terms were also sometimes used to represent similar offices. For example, Anglo-Norman comital functions for larger districts were executed by vicomtes in Normandy, and sheriffs in England. In contrast, the or advocate as an offic ...

Neuroanatomy
Neuroanatomy is the study of the structure and organization of the nervous system. In contrast to animals with radial symmetry, whose nervous system consists of a distributed network of cells, animals with bilateral symmetry have segregated, defined nervous systems. Their neuroanatomy is therefore better understood. In vertebrates, the nervous system is segregated into the internal structure of the brain and spinal cord (together called the central nervous system, or CNS) and the series of nerves that connect the CNS to the rest of the body (known as the peripheral nervous system, or PNS). Breaking down and identifying specific parts of the nervous system has been crucial for figuring out how it operates. For example, much of what neuroscientists have learned comes from observing how damage or "lesions" to specific brain areas affects behavior or other neural functions. For information about the composition of non-human animal nervous systems, see nervous system. For information a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vladimir Lenin
Vladimir Ilyich Ulyanov ( 187021 January 1924), better known as Vladimir Lenin, was a Russian revolutionary, politician and political theorist. He was the first head of government of Soviet Russia from 1917 until Death and state funeral of Vladimir Lenin, his death in 1924, and of the Soviet Union from 1922 until his death. As the founder and leader of the Bolsheviks, Lenin led the October Revolution which established the world's first socialist state. His government won the Russian Civil War and created a one-party state under the Communist Party of the Soviet Union, Communist Party. Ideologically a Marxist, his developments to the ideology are called Leninism. Born into a middle-class family in Simbirsk in the Russian Empire, Lenin embraced revolutionary socialist politics after Aleksandr Ulyanov, his brother was executed in 1887 for plotting to assassinate Alexander III of Russia, the tsar. He was expelled from Kazan Imperial University for participating in student prote ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kaiser Wilhelm Society
The Kaiser Wilhelm Society for the Advancement of Science () was a German scientific institution established in the German Empire in 1911. Its functions were taken over by the Max Planck Society. The Kaiser Wilhelm Society was an umbrella organisation for many institutes, testing stations, and research units created under its authority. History Constitution The Kaiser Wilhelm Gesellschaft (KWG) was founded in 1911 as a research institution outside the university system in order to advance the interests of German state and capital through the development of scientific knowledge relevant to industrial and military application. The inaugural meeting was held on 11 January 1911. The constituent institutes were established in succession and placed under the guidance of prominent directors, whose ranks included the physicists and chemists Walther Bothe, Peter Debye, Albert Einstein, Fritz Haber and Otto Hahn; a board of trustees also provided guidance.

Adolf Hitler
Adolf Hitler (20 April 1889 – 30 April 1945) was an Austrian-born German politician who was the dictator of Nazi Germany from 1933 until Death of Adolf Hitler, his suicide in 1945. Adolf Hitler's rise to power, He rose to power as the leader of the Nazi Party, becoming Chancellor of Germany#Nazi Germany (1933–1945), the chancellor in 1933 and then taking the title of in 1934. His invasion of Poland on 1 September 1939 marked the start of the Second World War. He was closely involved in military operations throughout the war and was central to the perpetration of the Holocaust: the genocide of Holocaust victims, about six million Jews and millions of other victims. Hitler was born in Braunau am Inn in Austria-Hungary and moved to German Empire, Germany in 1913. He was decorated during his service in the German Army in the First World War, receiving the Iron Cross. In 1919 he joined the German Workers' Party (DAP), the precursor of the Nazi Party, and in 1921 was app ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Politburo
A politburo () or political bureau is the highest organ of the central committee in communist parties. The term is also sometimes used to refer to similar organs in socialist and Islamist parties, such as the UK Labour Party's NEC or the Political Bureau of Hamas. Politburos are part of the governing structure in most former and existing states. Names The term ''politburo'' in English comes from the Russian ''politbyuro'' (), itself an abbreviation of ''politicheskoye byuro'' ( 'political bureau'). The Spanish term ''Politburó'' is directly loaned from Russian, as is the German ''Politbüro''. Chinese uses a calque (), from which the Vietnamese ( ), and Korean ( ''Jeongchiguk'') terms derive. History The first politburo was created in Russia by the Bolshevik Party in 1917 during the Russian Revolution that occurred during that year. The first Politburo had seven members: Vladimir Lenin, Grigory Zinoviev, Lev Kamenev, Leon Trotsky, Joseph Stalin, Grigori Sokol ...

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. Cytoarchitectonics is one of the ways to parse the brain, by obtaining sections of the brain using a microtome and staining them with chemical agents which reveal where different neurons are located. The study of the parcellation of ''nerve fibers'' (primarily axons) into layers forms the subject of myeloarchitectonics (from Greek μυελός 'marrow' and ἀρχιτεκτονική 'architecture'), an approach complementary to cytoarchitectonics. History of the cerebral cytoarchitecture Defining cerebral cytoarchitecture began with the advent of histology—the science of slicing and staining brain slices for examination. It is credited to the Viennese psychiatrist Theodor Meynert (1833–1892), who in 1867 noticed regional variations in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Morphometrics
Morphometrics (from Greek μορΦή ''morphe'', "shape, form", and -μετρία ''metria'', "measurement") or morphometry refers to the quantitative analysis of ''form'', a concept that encompasses size and shape. Morphometric analyses are commonly performed on organisms, and are useful in analyzing their fossil record, the impact of mutations on shape, developmental changes in form, covariances between ecological factors and shape, as well for estimating quantitative-genetic parameters of shape. Morphometrics can be used to quantify a trait of evolutionary significance, and by detecting changes in the shape, deduce something of their ontogeny, function or evolutionary relationships. A major objective of morphometrics is to statistically test hypotheses about the factors that affect shape. "Morphometrics", in the broader sense, is also used to precisely locate certain areas of organs such as the brain, and in describing the shapes of other things. Forms Three general appro ...

Grey Matter
Grey matter, or gray matter in American English, is a major component of the central nervous system, consisting of neuronal cell bodies, neuropil ( dendrites and unmyelinated axons), glial cells ( astrocytes and oligodendrocytes), synapses, and capillaries. Grey matter is distinguished from white matter in that it contains numerous cell bodies and relatively few myelinated axons, while white matter contains relatively few cell bodies and is composed chiefly of long-range myelinated axons. The colour difference arises mainly from the whiteness of myelin. In living tissue, grey matter actually has a very light grey colour with yellowish or pinkish hues, which come from capillary blood vessels and neuronal cell bodies. Structure Grey matter refers to unmyelinated neurons and other cells of the central nervous system. It is present in the brain, brainstem and cerebellum, and present throughout the spinal cord. Grey matter is distributed at the surface of the cerebral hemisp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wilder Penfield
Wilder Graves Penfield (January 26, 1891April 5, 1976) was an American-Canadian neurosurgeon. He expanded brain surgery's methods and techniques, including mapping the functions of various regions of the brain such as the cortical homunculus. His scientific contributions on neural stimulation expand across a variety of topics including hallucinations, illusions, dissociation and ''déjà vu''. Penfield devoted much of his thinking to mental processes, including contemplation of whether there was any scientific basis for the existence of the human soul. Life and career Early life and education Born in Spokane, Washington, on January 26, 1891, Penfield spent most of his early life in Hudson, Wisconsin. He studied at Princeton University, where he was a member of Cap and Gown Club and played on the football team. After graduation in 1913, he was hired briefly as the team coach. In 1915 he obtained a Rhodes Scholarship to Merton College, Oxford, where he studied neuropatho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pyramidal Cell
Pyramidal cells, or pyramidal neurons, are a type of multipolar neuron found in areas of the brain including the cerebral cortex, the hippocampus, and the amygdala. Pyramidal cells are the primary excitation units of the mammalian prefrontal cortex and the corticospinal tract. One of the main structural features of the pyramidal neuron is the conic shaped soma, or cell body, after which the neuron is named. Other key structural features of the pyramidal cell are a single axon, a large apical dendrite, multiple basal dendrites, and the presence of dendritic spines. Pyramidal neurons are also one of two cell types where the characteristic sign, Negri bodies, are found in post-mortem rabies infection. Pyramidal neurons were first discovered and studied by Santiago Ramón y Cajal. Since then, studies on pyramidal neurons have focused on topics ranging from neuroplasticity to cognition. Structure One of the main structural features of the pyramidal neuron is the conic sha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
