Related to Broca's: Broca's aphasia, Wernicke's


a type of speech disorder consisting of a defect or loss of the power of expression by speech, writing, or signs, or of comprehension of spoken or written language, due to disease or injury of the brain centers, such as after stroke syndrome on the left side.
Patient Care. Aphasia is a complex phenomenon manifested in numerous ways. The recovery period is often very long, even months or years. Because communication is such a vital part of everyday living, loss of the ability to communicate with words, whether in speaking or writing, can profoundly affect the personality and behavior of a patient. Although aphasic persons usually require extensive treatment by specially trained speech patholigists or therapists, all persons concerned with the care of the patient should practice techniques that will help minimize frustration and improve communication with such patients.
amnestic aphasia anomic aphasia.
anomic aphasia inability to name objects, qualities, or conditions. Called also amnestic or nominal aphasia.
ataxic aphasia expressive aphasia.
auditory aphasia loss of ability to comprehend spoken language. Called also word deafness.
Broca's aphasia motor aphasia.
conduction aphasia aphasia due to a lesion of the pathway between the sensory and motor speech centers.
expressive aphasia motor aphasia.
fluent aphasia that in which speech is well articulated (usually 200 or more words per minute) and grammatically correct but is lacking in content and meaning.
global aphasia total aphasia involving all the functions that go to make up speech and communication.
jargon aphasia that with utterance of meaningless phrases, either neologisms or incoherently arranged known words.
mixed aphasia combined expressive and receptive aphasia.
motor aphasia aphasia in which there is impairment of the ability to speak and write, owing to a lesion in the insula and surrounding operculum including Broca's motor speech area. The patient understands written and spoken words but has difficulty uttering the words. See also receptive aphasia. Called also logaphasia and Broca's, expressive, or nonfluent aphasia.
nominal aphasia anomic aphasia.
nonfluent aphasia motor aphasia.
receptive aphasia inability to understand written, spoken, or tactile speech symbols, due to disease of the auditory and visual word centers, as in word blindness. See also motor aphasia. Called also logamnesia and sensory or Wernicke's aphasia.
sensory aphasia receptive aphasia.
visual aphasia alexia.
Wernicke's aphasia receptive aphasia.

mo·tor a·pha·si·a

a type of aphasia in which there is a deficit in speech production or language output, often accompanied by a deficit in communicating by writing, signs, or other manifestation. The patient is aware of the impairment.

expressive aphasia

Broca’s aphasia

Loss of language ability due to damage in Broca's area (Brodmann area 44 and 45), characterised by telegraphic speech in which the meaning is usually clear but the grammatical connecting words are missing, with retained comprehension.

Stroke, usually due to thromboembolism; less commonly due to brain tumours, cerebral haemorrhage, extradural haematoma.

ex·pres·sive a·pha·si·a

(eks-pres'iv ă-fā'zē-ă)
A type of aphasia in which the greatest deficit is in speech production or language output; usually accompanied by a deficit in communicating by writing, signs, or other means. The patient is aware of this impairment. The lesion typically includes the posterior frontal lobe.
Synonym(s): Broca aphasia (2) , motor aphasia, nonfluent aphasia.

Neuroimaging studies have demonstrated that brain areas activated during speaking are notoriously larger than the classical Broca's area (Ardila, Bernal, & Rosselli, 2016d; Gernsbacher & Kaschak, 2003; Pickering & Garrod, 2013).
Broca's area has since ranked among the brain's most closely examined language regions in cognitive psychology.
Although Firmin's entry into the Societe occurred more than a decade later, it seems clear that Broca's recent death had unsettled the balance of power and re-agitated old disputes.
When speaking of nonfluent and fluent aphasia, most researchers still mean Broca's and Wernicke's aphasia.
When Leborgne died shortly thereafter of a gangrenous infection, Broca's autopsy revealed a lesion in a part of the brain he referred to as the circonvolution du language, now known as Broca's area.
MR results showed that Broca's area is apparently normal in autistic boys who have normal language capabilities.
The objective of this work, performed in postmortem human brains, is to determine the weight and cortical surface percentage of compensation and asymmetry of three brain regions of the frontal lobe: 1) Broca's area; 2) the anterior portion of the inferior frontal gyrus, 3) the inferior frontal gyrus as a whole.
Broca's area has long been associated with speech functions, but it is the first time specific parts have been identified.
To determine if Broca's area plays a critical role in human imitation, we conducted a repetitive transcranial magnetic stimulation (rTMS) study, transiently disrupting cortical activity in three sites: the left inferior frontal gyrus (Broca's area), right inferior frontal gyrus, and an occipital control condition.
Broca's remarkable career would revolve around 2 lasting interests--medicine and anthropology.
The brain pathway for normal reading has also been identified (from visual area to angular gyrus to Wernicke's area to Broca's area), as have the sequences involved in memory storage.
