The speech center of our brain is located in the left hemisphere, specifically the Broca's
The current study was planned to explore the outcomes of script training in a patient with Broca's
aphasia through quantitative approach using a single-subject-multiple-baseline research design across behaviours.
Traditionally, it has been accepted that speech production is controlled by the so-called Broca's
area corresponding to Brodmann's area (BA) 44 (pars opercularis of the left inferior frontal gyrus) (e.g., Goldstein, 1948; Damasio & Geschwind, 1984; Head, 1926; Hecaen, 1972; Luria, 1947/1970).
TEHRAN (FNA)- The brain's speech area, named after 19th century French physician Pierre Paul Broca, shuts down when we talk out loud, according to a new study that challenges the long-held assumption that 'Broca's
area' governs all aspects of speech production.
All participants had a clinical profile of Broca's
aphasia (nonfluent speech, relatively preserved comprehension, and impaired repetition).
In the years immediately following his death, a power struggle ensued between prominent factions of the organization, most notably Broca's
protege and presumed successor Paul Topinard and Firmin's eventual sponsor Mortillet.
The dyslexics showed less coordination between the 13 brain regions that process basic phonemes and a region of the brain called Broca's
area, which is involved in higher-level language processing.
Focusing on Paul Broca's
role, and discussing his views as a member of the French Senate, his personal life, and other interests that led him to the exploration of what became known as Broca's
area, he also describes the historical context of Descartes, reason, and the scientific method; the context of the Enlightenment; the roles of Bouillaud, Aubertin, and others; the contribution of phrenology to the understanding of localization of functions of the brain; the cases of Leborgne and Lelong; and Broca's
contributions to cancer, handedness, anthropology, genetics, cranial anthropometry, trepanation, and other subjects.
evaluated 65 aphasia patients during the acute stage and reported a mean age of 55.1 for Broca's
aphasia, 65.5 for Wernicke's aphasia, and 64.6 for global aphasia (14).
Over the last several decades, a large part of aphasia research has focussed on persons with Broca's
aphasia and agrammatism, although these people are relatively rare in the clinical setting, comprising perhaps 1-2% of the aphasic clients seen.
His research led to historical explanations and scientific research, especially Broca's
discovery that the brain is divided into two halves and joined by a web of connections that cause the left brain to control the right side of the body and vice-versa.
