Broca's aphasia is a speech and language syndrome caused by brain injury that is characterized by an impaired ability to speak fluently but with relatively intact language comprehension. The area was called broca's area, and the deficit in language production broca's aphasia wernicke's area is located in the parietal and temporal lobe and it is the sensory area wernicke's area helps in understanding written and spoken language. Wernicke's aphasia happens because the posterior portion of the left side of the brain has been damaged this area of the brain is responsible for reading, thinking of what to write, and understanding information. The broca area is connected to the wernicke area, by the arcuate fasciculus (nerve fibres) the condition of broca's area heavily affects speech and language comprehension in the human brain damage to the area (or frontal lobe) can cause broca aphasia (speech disorder.

For instance, wernicke's area is associated with language comprehension, whereas a separate area, broca's area, is associated with speech and language expression introduction to the nervous system, part 2: the autonomic nervous system and the central nervous system. Broca's area was named after paul broca, a french doctor of the nineteenth century carl wernicke was a german physician he gave his name to wernicke's area and lived until the start of the twentieth century. Broca's area or the broca area / b r oʊ ˈ k ɑː / or / ˈ b r oʊ k ə / is a region in the frontal lobe of the dominant hemisphere, usually the left, of the hominid brain with functions linked to speech production.

Wernicke's area has been interpreted as a more ancient structure than broca's area (aboitiz and garcía 1997), in part, because area tpt appears in some prosimians (preuss and goldman-rakic 1991. Marie suggested that aphasia required damage to wernicke's area and that broca's aphasia was a combination of aphasia, caused by damage to wernicke's area, and anarthria, a motor speech problem caused by damage to what he referred to as the lenticular zone, a collection of subcortical structures such as the putamen and pallidum. Wernicke's aphasia: persons diagnosed with wernicke's aphasia are unaware that the words they are producing are incorrect and nonsensical he or she may have severe comprehension difficulties and be unable to grasp the meaning of spoken words, yet may be able to produce fluent and connected speech. Wernicke's area (/ ˈ v ɛər n ɨ k ə / or / ˈ v ɛər n ɨ k i / template:ipa-de) is one of the two parts of the cerebral cortex linked, since the late nineteenth century, to speech (the other is broca's area) it is involved in the understanding of written and spoken language. The wernicke area is critical for speech production although the end product of speech production is a series of muscle movements, the brain mechanisms involved in speech production should not be seen as limited to motor commands that move muscles.

Areas of the brain affected by broca's and wernicke's aphasia what types of aphasia are there there are two broad categories of aphasia: fluent and nonfluent, and there are several types within these groups. The wernicke's area is located on the temporal lobe on the left side of the brain and is responsible for the comprehension of speech (broca's area is related to the production of speech) language development or usage can be seriously impaired by damage to this area of the brain.

The broca's area and wernicke's area, that contain motor neurons, are the language processing units of the brain that help in understanding language as well as allow us to communicate properly these are the language centers of the brain, and their proper functioning is very important to comprehend and speak any language.

Aphasia often arises as a result of damage to broca's area or wernicke's area aphasia is a language disorder that results from damage to portions of the brain that are responsible for language for most people, these are parts of the left side (hemisphere) of the brain. Wernicke's area is an important part of the brain that is involved with helping us to understand spoken language this lesson will cover where wernicke's area is located in the brain, how it works. Broca's aphasia (expressive) when a stroke injures the frontal regions of the left hemisphere, different kinds of language problems can occur this part of the brain is important for putting words together to form complete sentences.

Differences between broca's and wernicke's aphasia human beings occasionally suffer bad damage to particular parts of their brains unfortunately, these injuries may lead to major failure of speech production, understanding language and comprehension which most of the patients suffer it permanently. The region broca had discovered would first be known as broca's convolution, then broca's centre, and then---by the early 1900s---broca's area in addition to becoming recognized as an important part of the brain for language production, broca's area would be a critical piece of evidence in the debate over localization of function. This book discusses theories that link functions to specific anatomical brain regions the best known of these are the broca and wernicke regions, and these have become synonyms for the location of productive and receptive language functions respectively.
