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.
Wernicke's aphasia was named after German physician Carl Wernicke, who is credited with discovering the area of the brain responsible for language comprehension (Wernicke's area) and discovery of the condition which results from a lesion to this brain area (Wernicke's aphasia). [6] Although Wernicke's area (left posterior superior temporal ...
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.
Broca's and Wernicke's areas. Wernicke's area was named for German doctor Carl Wernicke, who discovered it in 1874 in the course of his research into aphasias (loss of ability to speak). This area of the brain is involved in language comprehension. [7] Therefore, Wernicke's area is for understanding oral language. [8]
He hypothesized that aphasia is the outcome of partial damage to the left auditory word center, whereas auditory agnosia is the result of complete damage to the same area. Bastian localized the auditory word center to the posterior MTG (middle temporal gyrus). Other opponents to the Wernicke-Lichtheim model were Sigmund Freud and Carl Freund.
Carl Wernicke discovered the sensory center of speech. Wernicke figured out that Broca's area was not the only center of speech, it was also able to distinguish motor aphasia from sensory aphasia. [77] He also pointed to the possibility of conduction aphasia since he came to understand the arrangement of the brain's extrinsic and intrinsic ...
Studies have suggested that conduction aphasia is a result of damage specifically to the left superior temporal gyrus and/or the left supramarginal gyrus. [5] The classical explanation for conduction aphasia is a disconnection between the brain areas responsible for speech comprehension (Wernicke's area) and that of speech production (Broca's ...
Paragrammatism is the confused or incomplete use of grammatical structures, found in certain forms of speech disturbance. [1] Paragrammatism is the inability to form grammatically correct sentences. It is characteristic of fluent aphasia, most commonly receptive aphasia.
