Some people may use the right hemisphere for language, and isolated damage of Wernicke's area cortex (sparing white matter and other areas) may not cause severe receptive aphasia. [5] [23] Even when patients with Wernicke's area lesions have comprehension deficits, these are usually not restricted to language processing alone.
There are obvious patterns for utilizing and processing language. In sign language, Broca’s area is activated while processing sign language employs Wernicke’s area similar to that of spoken language. [205] There have been other hypotheses about the lateralization of the two hemispheres.
We know this in part from what is lost when a stroke affects a particular part of the brain. Left hemisphere damage has many effects on language production and perception. Damage or lesions to the right hemisphere can result in a lack of emotional prosody [20] or intonation when speaking. [21]
(There is a wide distribution of Talairach coordinates [39] reported in the functional imaging literature that are referred to as part of Broca's area.) The processing of a passive voice sentence, for example, may require working memory to assist in the temporary retention of information while other relevant parts of the sentence are being ...
The angular gyrus is important in processing concrete and abstract concepts. It also has a role in verbal working memory during retrieval of verbal information and in visual memory when turning written language into spoken language. [9] The left AG is activated in semantic processing that requires concept retrieval and conceptual integration.
The temporal lobe is located beneath the lateral fissure on both cerebral hemispheres of the mammalian brain. [3] The temporal lobe is involved in processing sensory input into derived meanings for the appropriate retention of visual memory, language comprehension, and emotion association. [4]: 21 Temporal refers to the head's temples.
The earliest warning signs of Alzheimer's disease include memory loss that impacts your daily functioning, vision and language issues, social withdrawal, and more.
The angular gyrus is the part of the brain associated with complex language functions (i.e. reading, writing and interpretation of what is written). Lesion to this part of the brain shows symptoms of the Gerstmann syndrome : effects include finger agnosia, alexia (inability to read), acalculia (inability to use arithmetic operations), agraphia ...
