  Paul Pierre Broca - Wikipedia, the free encyclopedia
Broca soon became a professor of surgical pathology at the University of Paris and a noted medical researcher in many areas.
Broca is most famous for his discovery of the speech center of the brain (now known as the Broca's area, the third circumvolution of the frontal lobe).
Broca was also a pioneer in the study of physical anthropology.

 Aphasiology - Wikipedia, the free encyclopedia
Broca's aphasia, first described by the French neurologist Paul Broca in the nineteenth century, the speech of its suffers have a considerable vocabulary but is lacking even basic grammar.
The view of Broca's aphasia as an expressive disorder is supported by its frequent co-occurrence with facial motor difficulties, and its anatomical localization.
These studies demonstrate that the grammatical functions of Broca's area and the semantic functions of Wernicke's area are indeed deep, abstract properties of the language system independent of its modality of expression.

 PAUL BROCA - LoveToKnow Article on PAUL BROCA
It was in 1861 that he announced his discovery of the seat of articulate speech in the left side of the frontal region of the brain, since known as the convolution of Broca.
In his last years Broca turned from his labors in the region of craniology to the exclusive study of the brain, in which his greatest triumphs were achieved (see APHASIA).
He was decorated with the Legion of Honor in 1868, and was honorary fellow of the leading anatomical, biological and anthropological societies of the world.

 PIERRE PAUL BROCA AND THE SEAT OF THE FACULTY OF ARTICULATE LANGUAGE - Mind, Brain and Adaptation in the Nineteenth ...
Broca's localization of a centre for 'the faculty of articulate language' was the first localization of a function in the hemisphere which met with general acceptance from orthodox scientists.
It might be argued that Broca was the first to confirm this localization and to clarify it with clear-cut pathological evidence, but the fact is that the quality of the evidence of his original case was very dubious indeed.
Broca presented a second case of the same year,[5] from which he concluded that 'the aphemia was the result of a profound, but accurately circumscribed lesion of the posterior third of the second and third frontal convolutions'.[6] In this case the aphasia was not complicated by other symptoms, and the lesion was strictly limited.

Broca is also remembered for his contributions to anthropology, which include valuable studies of human skulls and the founding of the Societe dAnthropologie.
Broca's concepts on speech localization were initially based on the study of a single patient, Monsieur Leborgne, who was affected by epilepsy and who had lost the ability to speak.
Broca called this speech disturbance "aphemie," which was renamed by Armand Trousseau as "aphasia." Broca also described another form of speech disturbance, which he called "verbal amnesia," characterized by a loss of memory for spoken and written words.

Finally, a Broca region in the “strict sense” was distinguished from a region in a “broader sense” (Hervé, 1888; Riegele, 1931; Strasburger, 1938).
The concept of Broca’s region was introduced after Pierre Paul Broca had published two papers claiming the existence of a centre for articulated speech on the basis of an anatomo-clinical observation (1861a, b).
Broca’s publication was not the first that suggested a language centre in the left frontal lobe, and he was not the first to hypothesize left hemispheric dominance.

 Luigi Pirandello + Pierre Paul Broca
Broca's chief contribution to brain anatomy, based on observations of patients with brain damage who were unable to talk, was the discovery of the location in the brain of the speech center, which has become known as Broca's area.*
There was much church and state resistance to his founding of a Society for the study of the human species, and the Prefect of Police promised that Broca would be held responsible for anything said in meetings that may be "against society, religion, or the government." A police spy was assigned to monitor the proceedings.
Broca has been described as a Christian, but he must have practiced it lightly, because he founded a society for free-thinkers in 1848.

 Broca's aphasia
In 1865, Paul Broca described patients of his who were characterized by the sudden lack of the ability to speak, and a right hemiparesis.
Following the patients' death and post mortum examination, Broca demonstrated the region was in the left posterior frontal lobe, around the area of the operculum.
Broca's discovery spawned the notion that the brain was laterilized and compartmentalized.

This deep fold was described by Paul Broca as the pli de passage fronto-pariétal moyen, and the precentral bank of the pli de passage represents the anatomical substratum of hand motor function.
Broca's observations on aphasia popularized the notion that specific cortical functions can be localized on the surface of the brain.[25] This idea gave a new importance to the surface convolutions, and Broca was one of the early scientists to make meaningful and careful descriptions of cortical anatomy.

 Historical Background   (Site not responding. Last check: 2007-09-18)
Surgeon and physical anthropologist Paul Broca was the first to deduce that the left hemisphere is responsible for language functioning based on post-mortem study of nonfluent aphasic patients that had been in his care during their lives.
The region of interest is now known as Broca’s area; it is not responsible for all speech disorders, only those that are motoric and articulatory [10].
In 1985, Geshwind proposed a model of processing in the brain that interpreted aphasic disorders in terms of neural disconnection of cortical centers, the key components of which were Broca’s and Wernicke’s Areas and the connection between them, which he thought to receive input from a number of other structures [10].

, the name given by Paul Broca to a type of mankind supposed to be represented by remains found by Lartet, Christy and others, in France in the Cromagnon cave at Les Eyzies, Tayac district, Dordogne.
At the foot of a steep rock near the village this small cave, nearly filled with debris, was found by workmen in 1868.
The skulls presented such special characteristics that Broca took them as types of a race, Palaeolithic man is exclusively long-headed, and the dolichocephalic appearance of the crania (they had a mean cephalic index of 73.34) supported the view that the find at Les Eyzies was palaeoiithic.
