Expressive aphasia (also known as Broca's aphasia) is a type of aphasia characterized by partial loss of the ability to produce language (spoken, manual, [1] or written), although comprehension generally remains intact. [2] A person with expressive aphasia will exhibit effortful speech.
Expressive aphasia (non-fluent Broca's aphasia): this is generally considered the second main categorization of aphasia, where individuals have great difficulty forming complete sentences with generally only basic content words (leaving out words like "is" and "the"). Unlike Wernicke's aphasia, which causes patients to speak fluently, but ...
Wernicke's area (/ ˈ v ɛər n ɪ k ə /; German: [ˈvɛɐ̯nɪkə]), also called Wernicke's speech area, is one of the two parts of the cerebral cortex that are linked to speech, the other being Broca's area. It is involved in the comprehension of written and spoken language, in contrast to Broca's area, which is primarily involved in the ...
Aphasia. This is a disorder that impacts the way a person comprehends, speaks, and writes language. Aphasia usually is a result of traumatic head injury or stroke, but can have other causes such as tumors or progressive diseases. [18] There are several types of aphasia, with the two most popular being Broca’s Aphasia and Wernicke’s Aphasia.
For example, case studies have been performed with German speakers, which demonstrated that 30.8% of paraphasias occurred at the beginning of the word in patients with Wernicke's aphasia and 22.6% for patients with Broca's aphasia. In English speakers this tendency to create errors at the beginning of the word remained. [10]
The discovery of what is now known as Broca's area was followed years later by Carl Wernicke's famous work, 'The Symptom-Complex of Aphasia: A Psychological Study on an Anatomical Basis' in 1874. This paper is regarded as one of the most influential works in the history of the field of aphasiology.
Damage to Broca's area is commonly associated with telegraphic speech made up of content vocabulary. For example, a person with Broca's aphasia may say something like, "Drive, store. Mom." meaning to say, "My mom drove me to the store today." Therefore, the content of the information is correct, but the grammar and fluidity of the sentence is ...
The angular gyrus is represented in orange, the supramarginal gyrus is represented in yellow, Broca's area in blue, Wernicke's area in green, and the primary auditory cortex in pink. In neuroscience and psychology , the term language center refers collectively to the areas of the brain which serve a particular function for speech processing and ...
