Louis Pierre Gratiolet
Louis Pierre Gratiolet (; 6 July 1815 – 16 February 1865) was a French anatomist and zoologist who was a native of Sainte-Foy-la-Grande, Gironde. He succeeded Isidore Geoffroy Saint-Hilaire (1805-1861) as professor of zoology to the Faculty of Sciences at the University of Paris. Gratiolet is remembered for his work in neuroanatomy, physiognomy and physical anthropology. He did extensive research in the field of comparative anatomy, and performed important studies regarding the differences and similarities between human and various primate brains. He is also credited for introducing the demarcation of the brain's cortical surface into five lobes, (frontal lobe, temporal lobe, parietal lobe, occipital lobe and insular cortex). With Paul Broca (1824-1880) he performed correlative studies of aphasia and the frontal lobe. Gratiolet was a vocal critic of Broca regarding the latter's belief that a larger brain equated to higher intelligence. Associated eponym * Gratiolet's radi ...

Aphasia
Aphasia is an inability to comprehend or formulate language because of damage to specific brain regions. The major causes are stroke and head trauma; prevalence is hard to determine but aphasia due to stroke is estimated to be 0.1–0.4% in the Global North. Aphasia can also be the result of brain tumors, brain infections, or neurodegenerative diseases (such as dementias). To be diagnosed with aphasia, a person's speech or language must be significantly impaired in one (or more) of the four aspects of communication following acquired brain injury. Alternatively, in the case of progressive aphasia, it must have significantly declined over a short period of time. The four aspects of communication are auditory comprehension, verbal expression, reading and writing, and functional communication. The difficulties of people with aphasia can range from occasional trouble finding words, to losing the ability to speak, read, or write; intelligence, however, is unaffected. Expressive lan ...

19th-century French Writers
The 19th (nineteenth) century began on 1 January 1801 ( MDCCCI), and ended on 31 December 1900 ( MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanding beyond its British homeland for the first time during this century, particularly remaking the economies and societies of the Low Countries, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost all of Africa under colonial rule. It was also marked by the collapse of the la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

People From Gironde
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

French Wikipedia
The French Wikipedia (french: Wikipédia en français) is the French-language edition of Wikipedia, the free online encyclopedia. This edition was started on 23 March 2001, two months after the official creation of Wikipedia. It has articles as of , making it the -largest Wikipedia overall, after the English-, Cebuano-, Swedish- and German-language editions, the largest Wikipedia edition in a Romance language. It has the third-most edits, and ranks 6th in terms of depth among Wikipedias. It was also the third edition, after the English Wikipedia and German Wikipedia, to exceed 1 million articles: this occurred on 23 September 2010.

Hippopotamus
The hippopotamus ( ; : hippopotamuses or hippopotami; ''Hippopotamus amphibius''), also called the hippo, common hippopotamus, or river hippopotamus, is a large semiaquatic mammal native to sub-Saharan Africa. It is one of only two extant species in the family Hippopotamidae, the other being the pygmy hippopotamus (''Choeropsis liberiensis'' or ''Hexaprotodon liberiensis''). Its name comes from the ancient Greek for "river horse" (). Aside from elephants and rhinos, the hippopotamus is the largest land mammal. It is also the largest extant land artiodactyl. Despite their physical resemblance to pigs and other terrestrial even-toed ungulates, the closest living relatives of the hippopotamids are cetaceans (whales, dolphins, porpoises, etc.), from which they diverged about 55 million years ago. Hippos are recognisable for their barrel-shaped torsos, wide-opening mouths with large canine tusks, nearly hairless bodies, pillar-like legs, and large size: adults average ...

François Leuret
François Leuret (29 December 1797 – 5 January 1851) was a French anatomist and psychiatrist who was a native of Nancy. He studied medicine under Jean-Étienne Dominique Esquirol (1772–1840), and was later chief physician at the Bicêtre in Paris. Two of his better known students were Paul Broca (1824–1880) and Louis Pierre Gratiolet (1815–1865). Leuret was also chief-editor of ''Annales d’hygiène publique et de médecine légale'', an influential journal of hygiene and forensic medicine. Leuret is remembered for his work in comparative anatomy of the brain with Louis Gratiolet. The two men did extensive topographic mapping of the folds and fissures of the cerebral cortex. Leuret coined the name "fissure of Rolando" after Italian anatomist Luigi Rolando (1773–1831) for what is now known as the central sulcus of the brain. Leuret was an important figure in the early days of French psychiatry. He stressed the importance of using a rational and humane approach in t ...

Visual Cortex
The visual cortex of the brain is the area of the cerebral cortex that processes visual information. It is located in the occipital lobe. Sensory input originating from the eyes travels through the lateral geniculate nucleus in the thalamus and then reaches the visual cortex. The area of the visual cortex that receives the sensory input from the lateral geniculate nucleus is the primary visual cortex, also known as visual area 1 ( V1), Brodmann area 17, or the striate cortex. The extrastriate areas consist of visual areas 2, 3, 4, and 5 (also known as V2, V3, V4, and V5, or Brodmann area 18 and all Brodmann area 19). Both hemispheres of the brain include a visual cortex; the visual cortex in the left hemisphere receives signals from the right visual field, and the visual cortex in the right hemisphere receives signals from the left visual field. Introduction The primary visual cortex (V1) is located in and around the calcarine fissure in the occipital lobe. Each hemisphere's V1 ...
